A niche refers to the role and position a species has in its environment, which can include various aspects of its lifestyle. From the options provided, the following apply to the concept of a niche:
- It is where the organism lives.
- It is the food an organism eats.
- It is how the organism lives.
The other options do not accurately describe what a niche is. Specifically, "It is the primary and secondary consumer" is incorrect because a niche encompasses broader ecological roles, not just trophic levels, and "It is the number of organisms within the ecosystem" refers to population size, not niche.
