Transcript text: Which of the following is part of an organism's niche?
A. Food source
B. Equilibrium
C. Interspecific competition
D. Genes
Solution
The answer is A: Food source.
Explanation for each option:
A. Food source - Correct. An organism's niche includes its role in the ecosystem, which encompasses its food source, habitat, and interactions with other organisms.
B. Equilibrium - Incorrect. Equilibrium refers to a state of balance within an ecosystem, not a specific aspect of an organism's niche.
C. Interspecific competition - Incorrect. While interspecific competition (competition between different species) can influence an organism's niche, it is not a direct part of the niche itself.
D. Genes - Incorrect. Genes are part of an organism's genetic makeup, not its ecological niche.
Summary:
An organism's niche includes its food source, habitat, and interactions within the ecosystem. Therefore, the correct answer is A: Food source.
