Question

Fertilizers used on farms near the coast can be carried to the ocean when runoff occurs during rain showers. These fertilizers can decrease the populations of fish and shellfish. Which other populations most likely decrease as a result?

Answer 1

Answer:

Option 3

Explanation:

Options for the question

1. Organisms that eat algae
2. Organisms that live on farms
3. Organisms that eat fish and shellfish
4. All of these

Solution

The water of pool becomes oxygen deficient due to over growth of water plants in lieu to flow of fertilizers from farm land into it.

This will adversely affect the organism depending for oxygen in pool water. Thus, the population of fish and shellfish reduces. Now the population of organism that depends for food on fish and shellfish will also reduce. Hence , option 3 is correct
