Large areas of land are being developed. in the process thousands of trees are being removed and bumes
how would this affect the cycle?

Removing trees  in large amount can cause climate change, extinction of species and hence the food cycle as well as the ecosystems

Explanation:

Deforestation is the major cause of climate change. The atmosphere gets filled with greenhouse gases which would lead to an increase in temperature. We need oxygen to live which is coming from the plants, removing would affect these cycles. several species of animals have been already extinct and continuation of this activity would end up the removal of many organisms from the food cycle and finally, we will be removed.

it's c. (to reduce the greenhouse effect/carbon gasses)

sorry, but you do not have posted the diagram.
