Final answer:
Every animal requires a proper arrangement of essential items for survival, and these constitute its habitat, which is the specific natural environment including both biotic and abiotic factors to which the animal is adapted.
Step-by-step explanation:
To survive, every animal needs a proper arrangement of food, water, cover, and space. These items make up the animal's habitat.
A habitat is the natural environment in which a species lives and to which it is adapted. This includes both biotic (living) and abiotic (non-living) factors. An ecosystem is a broader concept that includes all these factors plus the interactions between them. The term ecological niche refers to the role a species plays within its ecosystem, encompassing its behaviors, interactions with other species, and its place in the flow of energy and nutrients. A niche is distinct in that two different species cannot occupy the exact same niche within the same ecosystem for long, due to competitive exclusion. Every species is adapted to its specific niche, which determines its dietary behaviors and how it meets its nutritional requirements within its habitat.
