Questions: Which of the following is an example of a biotic potential factor? lack of sunlight adequate food supply poor pH levels too much rainfall

The answer is the second one: adequate food supply.

Explanation for each option:

1. Lack of sunlight: This is an abiotic factor. Sunlight is a non-living component of the environment that can affect living organisms, but it is not a factor of biotic potential.

2. Adequate food supply: This is a biotic potential factor. Biotic potential refers to the capacity of a population to increase under ideal environmental conditions, and an adequate food supply is a living resource that supports population growth.

3. Poor pH levels: This is an abiotic factor. pH levels are a chemical characteristic of the environment and are not related to the biotic potential of a population.

4. Too much rainfall: This is an abiotic factor. Rainfall is a non-living environmental factor that can influence living organisms but does not directly relate to biotic potential.

In summary, biotic potential factors are those that involve living resources or conditions that support the growth and reproduction of a population, such as an adequate food supply.
