20
Q

21
Q

Define nitrogen fixation

A

Taking nitrogen from the atmosphere and turning it into ammonia

22
Q

Define nitrification

A

Transformation of ammonia to nitrate

23
Q

Define Denitrification

A

Nitrate reduction from atmosphere

24
Q

Define Trophic level

A

Animals that share same function in food chain

25
Q

What is a food chain?

A

Shows the flow of energy between animals and plants

26
Q

What is a food web?

A

Shows who eats what

27
Q

Why does only 10% of the energy make it to the next trophic level?

A

The other 90% is used when it dies and gives off heat and waste.

28
Q

What is each part of the water cycle?

A

Precipitation, runoff, evaporation/transpiration, condensation then back to precipitation

29
Q

What is each part of the carbon cycle?

A

Producers and consumers produce CO2 through cellular respiration, then when they die they become decomposers which become fossil fuels which then produce CO2

30
Q

Why is nitrogen needed by living things?

A

Nitrogen is a part of amino acids and amino acids make protein which provides structure and enzymes so without nitrogen we wouldn’t have any of those things.
