Organisms compete for which types of resources?

• A. Biotic and Abiotic factors such as food, mates, light, water, soil, temperatures, etc.
• B. Only biotic factors.
• C. Only abiotic factors.
• D. Mates and food only.

Answer: (A)

Competition happens when organisms try to use the same limited resources needed for survival, growth, and reproduction. Those resources can be biotic (coming from living things) or abiotic (nonliving parts of the environment). Biotic resources include things like food and mates, while abiotic resources include light, water, soil nutrients, and temperature. Since competition can involve both types, the best answer includes both biotic and abiotic resources. The other options miss part of the picture by restricting resources to living factors, nonliving factors, or just a couple of examples like mates and food.
