1 Objective: Students will describe biotic and abiotic parts of an ecosystem in which organisms interact; and compare these interactions terrestrial ecosystems

2 P TEMPERATURE A biome is a large region with certain climate and specific types of plants and animals adapted to live there. Earth has many different biomes and each has a number of different ecosystems.

3 Each ecosystem provides the living and nonliving things that allow certain plants and animals to survive.

4 The living things or biotic factors include plants, animals and microorganisms.

5 The nonliving or abiotic factors include water, temperature, air and soil.

19 BIOMES OF NORTH AMERICA Use the information from the resources provided to complete the data table on the back of your handout. Use the information from the resources provided to complete the data table on the back of your handout.

20 Tundra The North American tundra is found through out much of Alaska. Tundra is classified as being very cold with little rainfall.

21 Tundra Tundra soil has permafrost---the soil layer below the surface is always frozen. Because of this, only mosses, lichens, and shallow- rooted grasses and shrubs can grow in the surface soil above the permafrost. lichen

22 Caribou, polar bears, ground squirrels, and arctic fox are a few of the animals that live on a tundra. Caribou, polar bears, ground squirrels, and arctic fox are a few of the animals that live on a tundra.

23 Coniferous Forest (Taiga) Located in northern United State and mountainous regions, this biome is generally cold, and receives a lot of rain and snow. Soils thaw in the summer months and allow for tree growth. Located in northern United State and mountainous regions, this biome is generally cold, and receives a lot of rain and snow.

24 Trees are primarily coniferous (evergreen) with pine needles that stay on the trees year round. Trees are primarily coniferous (evergreen) with pine needles that stay on the trees year round.

26 Deciduous Forest These forests are found through out eastern United States and even into parts of Texas. These forests are found through out eastern United States and even into parts of Texas.

27 These forests are warm in the summer and cold in winter. They receive average amounts of rainfall that helps support plant growth. These forests are warm in the summer and cold in winter. They receive average amounts of rainfall that helps support plant growth.

28 Temperate forests have rich soils that support the growth of many species of grasses, shrubs and trees ---many of them deciduous. A deciduous tree has leaves that change color and fall off before winter.

29 Animals such as black bears, raccoons, squirrels, owls, woodpeckers and insects live in deciduous forests. Animals such as black bears, raccoons, squirrels, owls, woodpeckers and insects live in deciduous forests.

30 Rain Forest Located in Hawaii, the North American rainforest is known for its consistently high temperatures and a lot of rain. These conditions allow thick, tall forests to grow, along with the worlds greatest diversity of plants and animals.

31 Many plants, such as orchids, grow on tree trunks in tropical rainforests. Soils are generally poor and shallow as the rains wash the nutrients away.

32 Hundreds of species of birds, bats, insects, reptiles, amphibians and mammals, such as monkeys, find food and shelter here. Hundreds of species of birds, bats, insects, reptiles, amphibians and mammals, such as monkeys, find food and shelter here.

33 Grassland Grassland Located throughout the central part of the United States, the grassland biome is fairly dry. Located throughout the central part of the United States, the grassland biome is fairly dry.

34 The soils are fertile and that supports grasses and flowering plants. Grazing animals, fires, and droughts keep many trees from growing on this biome.

35 Bison, antelope, prairie dogs, and rabbits live in grasslands, where the soil is rich, summers are hot and winters are cold. Bison, antelope, prairie dogs, and rabbits live in grasslands, where the soil is rich, summers are hot and winters are cold.

36 DESERT DESERT Located in Southwestern United States, this biome has areas with high temperatures and very little rainfall and can therefore be classified as hot and dry.

37 Deserts have very little plant life because the soils are poor. Plants include short grasses, sagebrush, creosote bushes, and cacti. Deserts have very little plant life because the soils are poor. Plants include short grasses, sagebrush, creosote bushes, and cacti.
