Question

Which of the following factors is least likely to affect the type of organism colonizing a pond?

Options

• Acidity of water

• Age of pond

• Amount of rainfall

• Amount of sunlight falling on the pond

Answer 1

Age of pond

Explanation:

This is because acidity, rainfall, and sunlight directly influence the pond’s chemical and physical environment, affecting the survival and diversity of organisms. Age mainly affects ecosystem maturity but has a less immediate impact on the type of organisms present than other factors. Therefore, the pond’s age is less important than water acidity, rainfall amount, or sunlight availability in determining species colonization.
