d. the zebras are different sizes, indicating that multiple species of zebras are present.

Explanation:

1. Analyze option A: A water - hole is a non - living part of the ecosystem and is important as it provides water for various living organisms. It affects the distribution and behavior of animals in the area.
2. Analyze option B: A population consists of individuals of the same species. Springbok, zebras, and giraffes are different species, so they do not make up a single population.

4. Analyze option D: Zebras are a single species, and size variation within them is due to natural variation within the species, not different species.

Answer:

A. The water hole is an important nonliving part of the ecosystem.
