Question 35

the amount of rainfall and the average yearly temperature determine what?

Answer 35

what type of terrestrial biome you're in (climographs)

Question 36

- extremely dry not always hot - very little vegetation - large areas of no life

Answer 36

desert

Question 37

- large communities covered in grasses and other similar plants - usually has dry seasons so that little tree life can be supported - humus

Answer 37

temperate grasslands

Question 38

dead, decaying, plant and animal matter which helps make up the underlying soil

Answer 38

humus

Question 39

- medium precipitation, noticeable seasons - trees everywhere and must lose their leaves annually - clay found under humus - we live in temperate forest

Answer 39

temperate forest

Question 40

- characterized by intense rainfall, many species from all kingdoms and warm climates - located near equator - different levels within the forests providing many different niches - little humus because dead organisms decompose quickly

Answer 40

tropical rain forests

Question 41

- cold little rainfall - permafrost - short season of growing plants is a strong limiting factor - few large animals - horrible dark winters - north canada
