1 Ecosystems TAKS ACADEMY

2 1.How might the interactions of organisms in a specific habitat be helped or harmed as a result of changes in the ecosystem over time? 2.How might the biodiversity of the populations in a habitat affect organism interactions? 3.What is a microhabitat? 4.What is a biome and what abiotic factors characterize each biome? 5.How might biodiversity within and between trophic levels in a habitat affect sustainability of an ecosystem?


4 One individual by itself!
Organism One individual by itself! PERIOD NOTHING ELSE


6 Group of the SAME organisms living in the SAME place
POPULATION Group of the SAME organisms living in the SAME place


8 Group of DIFFERENT organisms living in the SAME place.
COMMUNITY Group of DIFFERENT organisms living in the SAME place.


10 ECOSYSTEM Living (biotic) and nonliving (abiotic) organisms interacting and living in the same place

11 What type of Ecosystem

12 WATER ECOSYSTEM FRESHWATER- The living organisms and nonliving materials of an inland aquatic environment OCEAN- The living and nonliving materials that cover most of the Earth’s surface with salt water

13 Water Cycle Used in all Ecosystems
The earth has a limited amount of water.  That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle". This cycle is made up of a few main parts: evaporation (and transpiration) condensation precipitation collection

14 Water Cycle

15 It can be more complex too… But the idea is simple…WATER GETS REUSED OVER and OVER!

16 LAND ECOSYSTEM DEFINITION-Also called biomes, these regions of land make up the Earth's surface. All of the Earth's surface, with the exception of the ice in Antarctica and Greenland, fits into a biome.

17 BIOME? WHAT IS A BIOME? An ecosystem that has similar climates, geography, plants, animals, and soil

18 Types of BIOMES

19 Tundra The tundra is the world's coldest and driest biome!
Not a lot of organisms or biodiversity Not a lot of plants! Short season of growth and reproduction Energy and nutrients in the form of dead organic material

20 Tundra Organisms Herbivorous mammals: lemmings, caribou, arctic hares and squirrels Carnivorous mammals: arctic foxes, wolves, and polar bears

21 Tundra Organisms Vegetation: lichens, mosses, and dwarfed shrubs
Migratory birds: ravens, snow buntings, falcons, loons, ravens, sandpipers, terns, snow birds Vegetation: lichens, mosses, and dwarfed shrubs

22 Tundra’s have LIVING and NONLIVING parts…
LIVING – Also know as BIOTIC Biotic Factors – Polar Bears, Wolves, Small shrubs, ravens, other birds, bacteria NONLIVING – Also known as ABIOTIC Abiotic Factors- Sunlight, temperature, snow (precipitation), wind, atmospheric gases.

23 Taiga The taiga is located near the top of the world, just below the tundra The winters in the taiga are very cold with only snowfall. The summers are warm, rainy, and humid. A lot of coniferous trees grow in the taiga.

24 CHAPARRAL The chaparral biome is found in a little bit of most of the continents - the west coast of the United States, the west coast of South America, the Cape Town area of South Africa, the western tip of Australia and the coastal areas of the Mediterranean. Lay of the land: The chaparral biome has many different types of terrain. Some examples are flat plains, rocky hills and mountain slopes. Chaparral is characterized as being very hot and dry. As for the temperature, the winter is very mild

25 Animals & Plants~ Chaparral
the plants and animals are adapted to these conditions. Most of the plants have small, hard leaves which hold moisture. Some of these plants are poison oak, scrub oak, Yucca Wiple and other shrubs, trees and cacti. The animals are all mainly grassland and desert types adapted to hot, dry weather. A few examples: coyotes, jack rabbits, mule deer, alligator lizards, horned toads, praying mantis, honey bee and ladybugs.

26 Prairie/Grasslands Areas that grass that get hot in the summer and cold in the winter Prairies are located in the inside of North America (Illinois) windy environment with few trees or shrubs moderate precipitation- about like we get

27 Organisms that live in Prairies and Grasslands
Vegetation – Grass! And a few trees, and shrubs.

28 Organisms that live in Prairies and Grasslands
Predators/ prey -gazelles, zebras, lions, wolves, prairie dogs, jack rabbits, deer, mice, foxes, skunks, badgers, blackbirds, quails, sparrows, hawks, owls, snakes, grasshoppers, and spiders.

29 Thinking Time Name some BIOTIC factors in the Grasslands or Prairies??? Name some ABIOTIC factors in the Grasslands of Prairies???

30 SAVANNAH A savanna is a rolling grassland scattered with shrubs and isolated trees, which can be found between a tropical rainforest and desert biome. They are found in a wide band on either side of the equator on the edges of tropical rainforests.

31 Organisms of the Savannah

32 Rainforest wet climate- that’s why its called a RAINforest!
home to 2/3’s of all the living animal and plant species on the planet natural rainforest gives off and sucks in large amounts of carbon dioxide. One-fifth of the world's fresh water is in the Amazon Basin.

33 Rainforest part of the Carbon Cycle???
natural rainforest gives off and sucks in large amounts of carbon dioxide. It taken in because of all the plants…they take in carbon dioxide through photosynthesis.. It gives off from dead plants and animals, animal waste, and organisms breathing it into the atmosphere (cellular respiration)

34 Carbon Cycle

35 Still the carbon cycle…

36 Even more carbon cycle..

37 Guess the carbon cycle doesn’t always have to look the same way.

38 Just one more carbon cycle…

39 Rainforest Organisms – HUNDREDS OF MILLIONS!! Monkeys, Toucans, Butterflies, Vines, Beetles, so many more!! *Get a lot of medicines from plants in Rainforest!!! You should thank them!

40 Ecological Succession of Rainforest
Experts estimate that we are losing 137 plant, animal and insect species every single day due to rainforest deforestation. (Cutting down the trees) What else could happen??? Cutting down all those trees???? Sad Rainforest Happy Rainforest

41 Desert Receives very little rain, Deserts are usually very, very dry!
few organisms can exist, Not a lot of plants or animals Temperature is very hot in the day, cool at night.

42 Desert Organisms Few large mammals live in deserts because most are not able to store enough water and resist the heat. Animals include small nocturnal (active at night) carnivores, animals stay inactive and hidden during the hot day and come out to hunt at night. Roadrunners, lizards, insects, small snakes, addax, Gila monster, desert fox, cacti, saguaro, and many other plants and animals

43 Wetlands Wetlands are areas of standing water that have aquatic plants. Marshes, swamps, and bogs are all considered wetlands Wetlands are found anywhere shallow bodies of water are present. Wetlands have the highest species diversity of all ecosystems.

44 Wetland’s Organisms Many species of amphibians, reptiles, birds (such as ducks and waders), and furbearers can be found in the wetlands. Plant species include pond lilies, cattails, sedges, tamarack, and black spruce

45 Wetlands Name 3 ABIOTIC things in the wetlands 1. 2. 3.
Examples: sunlight, water, soil, temperature, ect… Name 3 BIOTIC things in the wetlands 1. 2. 3. Examples: Lilies, snakes, toads, trees, moss, bacteria, ect…


47 Wetlands Food web Name a consumer in the food web…
Name a producer in the food web… Name decomposer in the food web…

48 How is the Nitrogen Cycle part of the Wetlands?
All organisms are part of the nitrogen cycle…we eat stuff with nitrogen in it and we release it back in to atmosphere Producers must convert it …78% of the atmosphere is nitrogen but we cant use it that way… IS THE NITROGEN CYCLE PART OF EVERY BIOME?

49 Nitrogen Cycle

50 Nitrogen cycle again..

51 Starting to get the point? Its doesn’t all look the same…

52 Deciduous Forest Deciduous means "tending to fall off"
The deciduous forest has four distinct seasons, spring, summer, autumn, and winter. As the seasons change, so do the colors of the leaves of the deciduous trees. located primarily in the eastern half of the United States, and some other places.

53 Deciduous Forest Animals/ Birds: American Bald Eagle, American Black Bear, Coyote, Duckbill Platypus ,Eastern Chipmunk ,European Red Squirrel, White-tailed Deer Vegetation: American Beech ,Carpet Moss, Common Lime Guelder Rose, Lady Fern, Northern Arrow wood ,Milksap, Mushroom,White Oak
