1 Ecosystems and Biomes Ecology The study of living things and their environment

2 Ecosystems and Biomes Graphic Organizer Water Living space Autotrophs Heterotrophs Food & water need made by eaten by to provide Food Living Things Homeostasis Shelter

3 Ecosystems and Biomes Some of the things that Living things need are 1)Biotic: Living/once living (Food) 2)Abiotc: Nonliving (water)

4 Ecosystems and Biomes Levels of Organization of Living Things

5 Ecosystems and Biomes Levels of Organization The smallest level of organization is a single organism, which belongs to a population that includes other members of its species. Living Things and the Environment

6 Ecosystems and Biomes Levels of Organization The population belongs to a community of different species. Living Things and the Environment

7 Ecosystems and Biomes Levels of Organization The community and abiotic factors together form an ecosystem. Living Things and the Environment

8 Ecosystems and Biomes Earth’s Major Cycles That effect living things

9 Ecosystems and Biomes The Water Cycle - Cycles of Matter The processes of evaporation, condensation, and precipitation make up the water cycle.

10 Ecosystems and Biomes The Carbon and Oxygen Cycles In ecosystems, the processes by which carbon and oxygen are recycled are linked. Producers, consumers, and decomposers play roles in recycling carbon and oxygen. - Cycles of Matter

11 Ecosystems and Biomes The Nitrogen Cycle - Cycles of Matter In the nitrogen cycle, nitrogen moves from the air to the soil, into living things, and back into the air.

12 Ecosystems and Biomes Food Chains, Webs, and Energy Pyramids

13 Ecosystems and Biomes Food Chains and Food Webs The movement of energy though an ecosystem can be shown in diagrams called food chains and food webs. - Energy Flow in Ecosystems

14 Ecosystems and Biomes - Ocean Habitats Ocean Food Web This ocean food web includes typical organisms found in the Arctic Ocean. The arrows indicate what each organism eats.

15 Ecosystems and Biomes Energy Flow in Ecosystems The amount of energy available decreases as you move up the pryamid

16 Ecosystems and Biomes Earth’s Biomes Land and Aquatic

17 Ecosystems and Biomes Rain Forest Biomes Temperate rain forests receive a great deal of rain and have moderate temperatures. - Biomes

18 Ecosystems and Biomes - Biomes Rain Forest Biomes Tropical rain forests are wet, warm biomes that contain an amazing variety of plants and other organisms.

19 Ecosystems and Biomes - Biomes Desert Biomes A desert is an area that receives less than 25 centimeters of rain per year.

20 Ecosystems and Biomes - Biomes Grassland Biomes A grassland is an area that is populated mostly by grasses and other nonwoody plants.

21 Ecosystems and Biomes Deciduous Forest Biomes Many of the trees in the deciduous forest are deciduous trees, which shed their leaves and grow new ones each year. A deciduous forest receives at least 50 centimeters of precipitation each year. Temperatures vary greatly through the year. - Biomes

22 Ecosystems and Biomes Boreal Forest (Tiaga) Biomes Most of the trees in the boreal forest are coniferous trees, trees that produce their seeds in cones and have leaves shaped like needles. Winters in the boreal forest are cold and very snowy, but summers are warm and rainy enough to melt all the snow. - Biomes

23 Ecosystems and Biomes - Biomes Tundra The tundra is an extremely cold and dry biome. Most of the soil in the tundra is permafrost, which is frozen all year.

24 Ecosystems and Biomes Character- istic Comparing and Contrasting As you read, compare and contrast the different biomes by completing a table like the one below. Warm all year - Biomes Tropical Rain Forest Tundra Temperate Rain Forest Desert Grassland Deciduous Forest Boreal Forest Tempera- ture Precipit- ation Typical organisms Cold all year Cool winters, warm in summer Usually hot with great daily extremes Temps vary throughout the year Warm in summer, cold in winter Warm to cool in summer, cold in winter Wet all yearDry all year Rather wet all year Dry all year Mostly dry with a wet season Moderate rainfall Abundant rain and snow OrangutanMosses Mule deer Gamble’s quail Grasses Red fox Lynx

25 Ecosystems and Biomes Marine Ecosystems The ocean is home to a number of different ecosystems. Factors such as water temperature and the amount of sunlight determine what types of organisms can live in each zone. - Aquatic Ecosystems

26 Ecosystems and Biomes Marine Ecosystems The ocean is home to a number of different ecosystems. Factors such as water temperature and the amount of sunlight determine what types of organisms can live in each zone. - Aquatic Ecosystems

27 Ecosystems and Biomes Rivers Headwaters Tributary Flood Plain Meander Mouth Ocean Delta

28 Ecosystems and Biomes How can an Ecosystem Change? Succession

29 Ecosystems and Biomes Primary succession is the series of changes that occur in an area where no soil or organisms exist. Changes in Communities Primary Succession

30 Ecosystems and Biomes Secondary Succession Secondary succession is the series of changes that occur in an area where the ecosystem has been disturbed, but where soil and organisms still exist. Changes in Communities

31 Ecosystems and Biomes Climate Change Human Impact on the environment

32 Ecosystems and Biomes What Is Pollution? Water pollution is the addition of any substance that has a negative effect on water or the living things that depend on the water. - Freshwater Pollution

33 Ecosystems and Biomes Water Pollution Wastes produced by households, agriculture, industry, mining, and other human activities can end up in water. Water Pollution and Solutions

34 Ecosystems and Biomes Effects of Pollutants A very small amount of a pesticide in water can build up to harmful levels in living things. - Freshwater Pollution

35 Ecosystems and Biomes Pollution Solutions People can prevent or clean up pollution in many ways. - Freshwater Pollution

36 Ecosystems and Biomes Global Climate Change The trapping of heat near Earth’s surface is called the greenhouse effect. Global Changes in the Atmosphere
