Nitrate reduction from atmosphere

Question 24

Define Trophic level

Answer 24

Animals that share same function in food chain

Question 25

What is a food chain?

Answer 25

Shows the flow of energy between animals and plants

Question 26

What is a food web?

Answer 26

Shows who eats what

Question 27

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

Answer 27

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

Question 28

What is each part of the water cycle?

Answer 28

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

Question 29

What is each part of the carbon cycle?

Answer 29

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

Question 30

Why is nitrogen needed by living things?

Answer 30

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.
