The correct answer is - a. biological action.

Explanation:

Biological action depends on microbes such as bacteria, nematodes, or other small organisms to treat and break down organic or biodegradable pollutants or wastes through the water process.

Water bodies have various types of pollutants including biologically degradable garbage, wastes, and partially digested foods. In some of the lakes and ponds pathogenic organisms, heavy metals, and toxins also found that are treated by these microbes.

the calvin cycle has three stages. in stage 1, the enzyme rubisco incorporates carbon dioxide into an organic molecule. in stage 2, the organic molecule is reduced. in stage 3, rubp, the molecule that starts the cycle, is regenerated so that the cycle can continue
