Which of the following is a major reason why organisms do not spread everywhere?

Organisms have limited resources.
Organisms have limited mobility.
Organisms have limited reproductive capacity.
Each species and each individual organism of a species has a particular range of tolerance to variations in chemical and physical factors in its environment. (correct)

What is the difference between ecological niche and habitat?

Ecological niche refers to the resources available in a particular environment, while habitat refers to the interactions between different species.
Ecological niche refers to the physical location where a species lives, while habitat refers to the role and position of a species in its environment.
Ecological niche refers to the interactions between different species, while habitat refers to the resources available in a particular environment.
Ecological niche refers to the role and position of a species in its environment, while habitat refers to the physical location where a species lives. (correct)

How can species be classified based on their niches?

Species can be classified based on their niches as herbivores or carnivores.
