Answer 28

WWwEVAPORATES

Question 29

Water from plants is released into clouds through what

Answer 29

TRASPIRATION

Question 30

In clouds water condenses into _________ rain falls back to earth

Answer 30

PERCIPITATION

Question 31

What cycle was that

Answer 31

WATER CYCLE

Question 32

What cycle is this, animals eat plants with nitrogen and N released into air when animals die an decay or release gases

Answer 32

NITROGEN

Question 33

From air _________ N returns to earth through lightning and rain

Answer 33

78%

Question 34

The role as species plays in a community

Answer 34

NICHE

Question 35

Carbon from burning _____________ is released into the air

Answer 35

FOSSIL FUELS

Question 36

Carbon taken into plants through ____________

Answer 36

PHOTOSYNTHESIS

Question 37

Explain why the boxes of an energy prymaid are larger at the bottom and smaller a the top. Give 2 examples that explain your answer.

Answer 37

BOXES OF AN ENERGY PYRAMID ARE LARGER AR THE BOTTOM BECAUSE PRODUCERS USE LESS ENERGY TO GET FOOD. Grass can make it;s own food. BOXES AR THE TOP ALL SMALLEST BECAUSE CARNIVORES USE LOT OF ENERGY TO GET FOOD. A WOLF MUST HUNT, CHASE, AND KILL IT'S FOOD.

Question 38

How does the CARBON CYCLE work?

Answer 38

Plants ---> decompose--->becoming fossil fuels---> burning fossils fuels---> air---> photosynthesis---> plants

Question 39

How does the NITROGEN CYCLE work?

Answer 39

plants---> eaten---> animals---> die&decpmoser/release gases---> air--->lightning&rain--->plants

Question 40

How does WATER CYCLE work?

Answer 40

plants---> transpoiration---> clouds---> condensation---> precipitation---> plants lakes--->evaporation--->clouds
