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.

Answer Northern Alaska
7. Where in the United States would you find tundra? Answer Northern Alaska
17
Answer Grassland with scattered wooded areas.
9. What type of biome is found over most of Texas? Answer Grassland with scattered wooded areas.
18
The abiotic factors (climate) determine what types of biotic factors will survive in that biome.
***How do the abiotic factors affect the biotic factors that live in each biome?

BIOMES OF NORTH AMERICA
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 lichen 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.
22
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 .
24
Trees are primarily coniferous (evergreen) with pine needles that stay on the trees year round.
25
Moose, wolves, elk, and porcupines live in a coniferous forest (taiga).
26
Deciduous Forest 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
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.
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 world’s 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.
33
Grassland 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
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.
36
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. DESERT
37
Deserts have very little plant life because the soils are poor
Deserts have very little plant life because the soils are poor. Plants include short grasses, sagebrush, creosote bushes, and cacti.
38
Jackrabbits, reptiles, birds, kangaroo rats and coyotes live in the North American desert.
