1. Tropical Rain Forest:
  2. Precipitation - 250cm/year Little temp. variation/abundant moisture Contains more species than other biomes.
  3. Savannahs- Precipitation 90-150cm/year Open, widely spaced trees, seasonal rainfall Parts of Africa, South America & Australia.
  4. Deserts- Precipitation 20cm/year Dry, sparce vegetation; scattered grasses Parts of Africa, Asia, Australia, North America.
  5. Temperate Grasslands- Precipitation: 10-60cm/year Rich soil; tall dense grasses Central North America; Central Asia.
  6. Deciduous Forests- 75-250cm/year Warm summers, cool winters Europe; NE United States;Eastern Canada.

1) The decomposer broke down the dead animal.

2) The consumer ate another animal.

3) The ecosystem had many living organisms such as plants, animals, and microbes.

4) The producer was able to produce its own food.

5) The grizzly bear was at the top of the food chain meaning it was an apex predator or decomposer.

6) The bug was no longer biotic because it got hit and killed by a bat.

7) There are not very many abiotic factors in a dark room.

8) Animals use adaptation to survive.

9) Biotic factors in a wetlands ecosystem are turtlehead flowers, water, trees, butterflires, competition, bacteria, carrying capacity, plaintain, ash, and the false foxglove.

10) Abiotic factors in a wetland ecosystem are sunlight, air, climate, soil, water, rocks, and temperature.

11) Grass - Grasshopper- Toad- Snake- Hawk- Bacteria of decay

12) It enters in the form of sunlight.

13) Energy transfers

14) The food chain would be destroyed and probably not existant anymore.

15) Wetlands have important filtering capabilities for intercepting surface- water runoff from higher dry land before the runoff reaches open water.

16) Wetlands act as natural sponges, soaking up the flood waters.

17) The ability of wetlands to control erosion is so valuable that some states are restoring wetlands in coastal areas to buffer the storm surges from hurricanes and tropical storms.

18) More than 1/3 of endangered animals live in the wetlands.

19) Natural products and recreation are popular in wetlands.
