1. BIOMES

3. * A biome is an area that has the same climate (weather) and the same organisms that live there. * Biomes help scientists describe the world. * There are approximately ____ land biomes and ___ water biomes 72

4. Biome Characteristics  Composed of large regions.  Have specific climate with similar plants and animal adaptations. ***Species composition is not the same in different areas. (Example deserts of Africa and the deserts of the U.S.)

5. Weather is the day to day change in temperature and precipitation. Ex: Today it will be warm with a 20% chance of rain. Climate is the long-term pattern of weather conditions in a region. WEATHER VERSUS CLIMATE

6. Latitudes Define Some Biomes Latitude refers to the distance from the equator. The closer an area is to the equator, the more solar energy and rainfall it receives. For Example, Tundra is from arctic circle to 70° N.

13. Black-collared lizard snakes camel desert iguana roadrunner jackrabbit

14. Animal adaptations: -Get water from seeds/plant parts(fruit); insects -Large ears to release heat -Nocturnal-coming out at night to eat and hunt. -Burrow underground to live

17. Where is the tundra? Around the North Pole and near the Arctic Ocean Climate (weather) Very cold and dry Temperature: winters lows -34°C summer highs 3-12° C Only has 25 centimeters or less of rain every year What the land looks like Permafrost: the dirt that is always frozen (even in the spring and summer) Flat land with only a few small, thin trees

18. Plant Adaptations: Permafrost restricts root growth; short roots. Small sized plants Very short growing season. Plants are dark and hairy (absorb solar heat and trap heat) Some grow in clumps for warmth Dish-like flowers that rack the sun Animal Adaptations: Fur/heavy coats (insulated under fur) Heat-efficient body shape: short limbs, ears, tails Camouflage (winter color and summer color coat) Hibernation(state of deep dormancy where heartbeat and respiration slows down)

22. There are _____ kinds of grasslands.two Temperate grasslands: called prairies Tropical grasslands: called savannas Climate All grasslands get between 25 and 75 centimeters of rain every year. Coniferous forest

23. The largest grassland is in Africa. There are also grasslands in North America, South America, central Asia, and northern Australia.

24. Some are found in the United States Illinois is on the prairie as well as Kansas, etc. Land is usually flat Not a lot of trees The most important plant is __________. Grass Bluestem grass, Buffalo grass, Indian grass, Stinging nettle, Coneflowers,

25. Largest savannas are found in Africa There are only a few trees on the savanna Why don’t a lot of trees grow? Savanna does not get a lot of rain People set the grass on fire to stop trees from growing Animals eat the trees before they can start growing tall

26. Grass – elephant grass Can live without a lot of rain Acacia tree Baobab tree

27. Grassland Plant and Animal Adaptations Plants –Extensive root webs (so grazing animals don’t pull up the entire root, or damaged by fires) –Thin, needle-like shaped leaves that expose little of the plant to the sun (grass leaves are needle shape) Animals Predators need to be quick, powerful, smart, and sneaky to bring down fast and alert animals Hunt in groups Camouflage

30. Climate Cold and snowy What the land looks like In the winter: Ground is frozen In the spring: Taiga: swampy forest Snow melts and the ground becomes wet and swampy because the deeper ground is frozen

31. In Canada, Alaska, northern Asia, and northern Europe EuropeAsia Canada Alaska

32. Plant and Animal Adaptations: Plant adaptations narrow needle-like wax structures limits water loss chemical that repels animals who would eat the needles dark green color of the needles absorbs the sunlight conical shape of the evergreens allows the snow to slide off the branches rather than pile up They are always green so don't have to regrow Animal adaptations migrate to warmer climates once the cold weather begins Some animals hibernate Some have a layer of insulating feathers or fur Seasonal change in color of feathers or fur protects the animal from its predators

33. Conifer trees (have cones) Have needles covered with wax Wax protects the needles from freezing cone needles Kinds of conifer trees pine fir spruce

37. Deciduous forests are between northeastern United States and Canada. Some are in the eastern United States. Others grow in Europe and eastern Asia.

38. Climate Summers are warm Winters are cold Gets 75 centimeters of rain every year (that’s over 2 feet of rain!) What is special about deciduous trees? The leaves change colors and fall off the trees in autumn and grow new leaves in the spring The leaves on the ground make the dirt better and help plants grow.

39. Plant and Animal Adaptations Plants: –Deciduous Trees are notable for going through four seasons. Loose their leaves. –Trees go into a period of dormancy or sleep. –Thick bark to protect them from the cold weather. Animals: -Hibernation -Migration -Stockpiles of food (nuts, seeds) -Camouflaged to look like the ground

43. Climate Rains almost everyday 200 cm this is almost 10 feet of rain every year. Very hot all year long

44. The largest tropical rainforest is in South America. It is called the Amazon rain forest. They are also found in central Africa, Central America, Southeast Asia, Hawaii, and a small area of Australia.

45. Plant and Animal Adaptations Plants –Thin smooth bark so vines have trouble growing on them –Vine like to reach sun from below -Buttress roots provide extra stability, roots are not deep

46. RAINFOREST ANIMAL ADAPTATIONS -Animals are very specialized and adapted for eating a specific plant or animal(different types of beaks etc. -Some are poisonous, and use bright colors to warn predators -Camouflage -Live in different levels of the rainforest

57. Alpine biomes by their nature do not fit into a simple climatic scheme. In general, as one ascends a mountain, temperature drops by about 10 degrees C for every 1000 meters in altitude gained. Rainfall also varies considerably; as the rising air cools it loses the ability to retain moisture and clouds form, with the result of increasing precipitation on the side of a mountain exposed to winds. On the other side, the descending air (already dried by its trip over the mountains) warms and removes moisture from the ground - this is one of the driving forces behind the deserts in the American Southwest.

58. World Distribution :

59. As one moves up a mountain, the first indication one has that you are entering an alpine area: Appearance of coniferous trees, able to shed snow easily, and retaining photosynthetic needles that are able to start photosynthesis quickly as soon as the temperature exceeds the freezing point, conifers such as firs and pines Further up the mountain a tree line occurs; above this point climactic conditions are too harsh for trees to grow, and a tundra-like plant community develops. Plants here include various wildflowers (below), mosses, succulents (adapted to the harsh dry conditions that often prevail), and other low-growing plants (below right). Lichens can also be important.

60. There are only about 200 species of Alpine plants. At high altitudes there is very little CO2, which plants need to carry on photosynthesis. most plants are small perennial groundcover plants which grow and reproduce slowly. They protect themselves from the cold and wind by hugging the ground. Most Alpine plants can grow in sandy and rocky soil. Plants have also adapted to the dry conditions of the Alpine biome. Plant books and catalogs warn you about over watering Alpine plants. Bristlecone pine Alpine Phacelia Polylepis Forest Bear Grass

61. Oxygen levels get thinner as you go up the mountain; animals have to adapt to this. Mountain goats, below, have a host of adaptations that allow them to live on the most precarious of cliffs. Chief among those adaptations are special pads on their hooves which are both cushioned (to absorb the shock of jumping from rock to rock) and slip resistant.

62. Alpine animals have to deal with two types There are only warm blooded animals in the Alpine biome, although there are insects. Alpine animals adapt to the cold by hibernating, migrating to lower, warmer areas, or insulating their bodies with layers of fat. Animals will also tend to have shorter legs, tails, and ears, in order to reduce heat loss. Alpine animals also have larger lungs, more blood cells and hemoglobin because of the increase of pressure and lack of oxygen at higher altitudes. Alpaca Mountain Goat ChinchillaAndean Condor

63. Alpine (Mountain) biomes are found in the mountain regions all around the world. They are usually at an altitude of about 10,000 feet or more. The Alpine biome lies just below the snow line of a mountain. As you go up a mountain, you will travel through many biomes. In the North American Rocky Mountains you begin in a desert biome. As you climb you go through a deciduous forest biome, grassland biome, steppe biome, and taiga biome before you reach the cold Tundra /Alpine biome.

64. * MarineMarine * FreshwaterFreshwater

65. The marine biome is the _________________ biome. ocean * covers about 70% of the Earth * has salt water Organisms that live in the ocean are adaptated to live in the salt water. * sunlight, water pressure, and water movement affect the organisms too - because of these things, the ocean is divided into different areas and different organisms live in each area The water that is very deep has cold temperatures, high pressures, and is very dark

66. Many of the plants live near the top of the water and they need the sunlight to help them grow and make food Seaweed and Kelp are examples of plant life **These ARE NOT plants although they may look like it

67. Plants Marine Animals Eelgrass Maerl Johnson’s Sea Grass Marsh Grass Sea Pickles Octopus Coral Sea anemone Dolphin Fish

68. Most marine organisms live near the top of the water or close to land **Many animals dig down into the sand or hang on to rocks, so they do not get lost in the sea Other larger animals live where the water is deep barracuda star fishclown fishcrab flashlight fish green sea turtlekiller whaleshrimp

70. ZONES The intertidal zone is where the ocean meets the land — sometimes submerged/other times exposed, (waves and tides come in and out). –the communities are constantly changing. Find algae and small animals, such as herbivorous snails, crabs, sea stars, and small fishes. –Neritic zone is the region of shallow water from low tide line to continental shelf The pelagic zone includes those waters further from the land, basically the open ocean. –Usually cold but has a constant mixing of warm and cold ocean currents. –Flora -surface seaweeds. –Fauna include many species of fish and some mammals, such as whales and dolphins. Many feed on the abundant plankton.

71. The benthic zone is the area below the pelagic zone, but does not include the very deepest parts of the ocean. – The bottom of the zone consists of sand, slit, and/or dead organisms. –Here temperature decreases as depth increases – Flora are represented primarily by seaweed – Fauna include all sorts of bacteria, fungi, sponges, sea anemones, worms, sea stars, and fishes. The deep ocean is the abyssal zone. –The water in this region is very cold (around 3° C), highly pressured, high in oxygen content, but low in nutritional content. –Fauna many species of invertebrates and fishes. –Due to hydrothermal vents along the ocean floors, chemosynthetic bacteria These bacteria are thus the start of the food web as they are eaten by invertebrates and fishes.
