How does deforestation affect the oxygen cycle ? A. It reduces the amount of oxygen produced . B. It increases the amount of photosynthesis . It destroys the aquifers that store oxygen . D. It increase the amount of oxygen produced .

A. It reduces the amount of oxygen produced

Explanation:

Deforestation reduces the amount of oxygen present in air and thereby, disturbs the oxygen cycle by reducing the oxygen content in its reservoir (the air). Explanation. Deforestation cuts down large number of trees. Less number of plants add lesser oxygen to the air and hence, the oxygen content of the air is reduced.

A.

Explanation: When someone cuts down a tree, you make see smoke. That's the chemical smoke filled with tons of harmful chemicals like acid, carbon dioxide, harmful oxygen, etc. That's why acid rain sometimes form where deforestation occurs.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
