Consider the following statements with respect to the 'Niche':

1. The ecological niche describes how an organism responds to the distribution of resources and competitors and it in turn alters those same factors.

2. Niche construction is the process in which an organism can only alter its own environment.

3. It is disadvantageous for species because it reduces the amount of competition for resources that species will encounter.

Which among the above given statements are incorrect?

1 and 3 only

All of the above

Niche construction is the process in which an organism alters its own (or other species') environment.
For example, through a process of modification, earthworms chemically alter the soil in which they live.
The ecological niche describes how an organism or population responds to the distribution of resources and competitors (for example, by growing when resources are abundant, and when predators, parasites and pathogens are scarce) and how it in turn alters those same factors.
It is advantageous for a species to occupy a unique niche in an ecosystem because it reduces the amount of competition for resources that species will encounter.
