Explanation:

Introduction:
In the given passage, a farmer is growing a crop regularly in his field using various methods such as chemical fertilizers, pesticides, organic manure, and bio-fertilizers. There is also a nearby factory emitting smoke as a byproduct, and a lake in the area. The question asks which organism in the food chain is likely to show the minimum amount of pesticide concentration after a considerable time.

Food Chain:
The food chain in the lake mentioned in the passage is as follows:
Aquatic plants → Small fish → Big fish → Birds

Pesticide Concentration in Organisms:
Pesticides are chemicals used to control pests and can have harmful effects on organisms if they accumulate in their bodies over time. The concentration of pesticides in organisms depends on various factors, including their position in the food chain and their ability to metabolize or eliminate the pesticides.

Explanation of Answer:
The aquatic plants in the food chain are likely to show the minimum amount of pesticide concentration after a considerable time.

Reasons:
1. Position in the Food Chain: Aquatic plants are at the base of the food chain. They obtain nutrients and energy from the water and sunlight through photosynthesis. Since they are not directly consuming other organisms, they are less likely to accumulate pesticides from the environment or through the food they consume.

2. Limited Ability to Accumulate Pesticides: Aquatic plants do not have a high ability to accumulate pesticides compared to animals. They do not have a complex metabolic system like animals, which can lead to the accumulation of pesticides in their bodies. Additionally, they do not have organs like liver or kidneys, which are involved in the detoxification and elimination of pesticides.

3. Rapid Growth and Replacement: Aquatic plants have a relatively fast growth rate and can replace their tissues quickly. This means that any pesticides that may be absorbed or accumulated in their tissues can be diluted or replaced more rapidly compared to organisms higher up in the food chain. This leads to a lower concentration of pesticides in their bodies over time.

4. Direct Exposure to Water: Aquatic plants are in direct contact with water, which can dilute and wash away any pesticides present in their tissues. They are constantly in contact with the water through which they obtain nutrients and eliminate waste, reducing the chances of pesticide accumulation.

Conclusion:
Based on the above reasons, it can be concluded that aquatic plants in the given food chain are likely to show the minimum amount of pesticide concentration in them after a considerable time.
