Read the following passage
Human body is made up of five important components, of which water is the main component. Food as well as potable water is essential for every human being. The food is obtained from plants through agriculture, Pesticides are being used extensively for a high yield in the fields. These pesticides are absorbed by the plants from the soil along with water and minerals and from the water bodies these pesticides are taken up by the aquatic animals and plants. As these chemicals are not biodegradable, they get accumulated progressively at each trophic level. The maximum concentration of these chemicals gets accumulated in our bodies and greatly affects the health of our mind and body.
The maximum concentration of pesticides are found in

Options

A. Man
B. Plants
C. Deer
D. Tiger

Explanation

**Step-by-Step Text Solution:**

1. **Understanding the Passage**: The passage discusses the composition of the human body, emphasizing that water is the main component. It also highlights the importance of food and potable water for human health.

2. **Role of Pesticides**: It mentions that pesticides are used in agriculture to increase crop yield. These pesticides are absorbed by plants from the soil and water, and they can also enter aquatic ecosystems.

3. **Bioaccumulation and Biomagnification**: The passage explains that pesticides are not biodegradable, meaning they do not break down in the environment. As a result, they accumulate in organisms at each trophic level, leading to higher concentrations in organisms higher up the food chain.

4. **Trophic Levels**: The concept of trophic levels is introduced. Humans are at the highest trophic level in the ecosystem, meaning they are at the top of the food chain and consume both plants and animals.

5. **Maximum Concentration in Humans**: Since humans are at the highest trophic level, they accumulate the maximum concentration of pesticides in their bodies, which can adversely affect their health.

6. **Conclusion**: The passage concludes that the maximum concentration of pesticides is found in humans, due to their position at the top of the food chain.

**Final Answer**: The maximum concentration of pesticides is found in humans, as they are at the highest trophic level in the ecosystem.
