<u>Answer:- </u> Decomposition
<u>Explanation:- </u>
Decomposition is a natural process that occurs in the environment to break down organic substances into simpler substances.
- All the living organisms that die, are decomposed and their bodies are broken down into simpler substances such that the nutrients are released into the soil.
- The plants are then able to absorb these nutrients from the soil and thus, the nutrient cycling goes on as the organisms feeds on it.
- Not only the dead animals but also the fallen leaves and other parts of the plant gets decomposed as they die.

The correct answer is filtration.
The small molecules can cross in and out of the capillaries through facilitated or simple diffusion. However, the majority of the flow of capillary and tissue fluid takes place through the process of filtration and reabsorption. Filtration refers to the movement of the fluid out of the capillaries and is mediated by the capillary hydrostatic pressure.
It seems to have choices. The exposure mutagens may lead to the mutation. When the mutation add up to a certain amount and can lead to cancer. So exposure mutagens will increase the cancer risk.
