Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.
Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.
Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

In an experiment that compares a combination mental-physical practice condition to an all-mental practice condition, an all-physical practice condition, and a no practice condition, the typical results show that participants in the combination mental-physical practice condition would learn the skill
a. as well as or better than those in the all-physical practice condition.
b. about as well as those in the all-mental practice condition.
c. about as well as those in the no practice condition.
d. The results would depend on the combination of the amount of mental and physical practice.
The combination mental-physical practice condition is effective to learn the skill as well as or better than those in the all-physical practice condition. Mental-physical practice enhances both cognitive and physical skills.
Mental practice, also known as mental/skill rehearsal, refers to the cognitive (i.e., thinking) rehearsal of a given skill prior to its execution.
It has been shown that mental practice can be effective for enhancing the performance of both cognitive and physical skills.
The mental-physical practice has been shown to be helpful to enhance self-motivation, confidence, and reduce feelings of anxiety.
Mental practices always must be employed to supplement physical practices instead of replacing such physical exercises.
