Question

in this section, you learned that all body matter is eventually replaced. how does this influence your understanding of how your own body is involved in biogeochemical cycles? name two human actions needed to slow climate change. describe some ways that climate change might influence the water cycle. plants need nitrogen to produce proteins and other important chemicals. describe how nitrogen in the atmosphere makes its way into plants. how is the nitrogen in dead organisms released back into the soil?

Explanation:

1. Our body matter replacement shows we are part of biogeochemical cycles. We take in and release elements like carbon, nitrogen etc. as our matter is replaced.
2. Two actions to slow climate - change: reduce fossil - fuel consumption (less CO2 emission) and plant more trees (absorb CO2).
3. Climate change can increase evaporation rates, change precipitation patterns and lead to more extreme weather events affecting the water cycle.
4. Nitrogen in the atmosphere is fixed by nitrogen - fixing bacteria into ammonia or other nitrogen - containing compounds. Plants can then take up these compounds through their roots.
5. Decomposers break down dead organisms. During decomposition, they release nitrogen - containing compounds back into the soil in the form of ammonium ions which can be further converted and taken up by plants.

Answer:

1. Our body's matter replacement indicates our active role in biogeochemical cycles.
2. Reducing fossil - fuel consumption, Planting more trees.
3. Increased evaporation, altered precipitation patterns, more extreme weather events.
4. Nitrogen - fixing bacteria fix atmospheric nitrogen into compounds plants can take up.
5. Decomposers break down dead organisms and release nitrogen into the soil.
