Answer:
Active transport mechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP).
Explanation:
If a substance must move into the cell against its concentration gradient, that is, if the concentration of the substance inside the cell must be greater than its concentration in the extracellular fluid, the cell must use energy to move the substance. Some active transport mechanisms move small-molecular weight material, such as ions, through the membrane.
In addition to moving small ions and molecules through the membrane, cells also need to remove and take in larger molecules and particles.

Habitat
Explanation:
All organisms are in constant interaction with their environment. This includes both biotic, living things, or abiotic, non-living things, factors. Where this interaction takes place is what we call an ecosystem.
Within each ecosystem, e.g. aquatic or terrestrial, <u>a population, or group of species, lives in a specific physical environment known as a habitat</u>, where they occupy their own niches or roles/functions.
Here, several populations of different species can coexist, however, they have their own roles or, in other words, they have specific adaptations to this area. Habitats could range from oceans, lakes, and rivers to deserts, forests, and mountains.
Therefore, a <u>habitat</u> is a physical environment where a species lives and becomes adapted.
