Answer:
1) Wax belong to lipids.
2) <u>Animals</u>: Water and cold isolation and protection from pathogenic microorganisms.
<u>Plants</u>: It controls evaporation and maintains hydration.
Explanation:
1) Wax belong to the biomolecules of lipids.
2) In animals, such as birds, the uropygial gland secrets sebum or wax, spreading it throughout the animal's feathers to prevent water from penetrating as it serves as an isolating compound for animals that live in cold areas. It also provides protection from bacteria and fungi. In coloquial terms, it would be like a water-proof coat that protects them from water and extreme climate.
In plants, the secretion of wax through the cuticle has been developed as an adaptation to control evaporation and maintain hydration.

Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground.
This indicator is an estimate of the amount of space on the earth that an individual uses in order to survive using existing technology. This space includes the biologically productive land and water area that produces the resources consumed by that individual such as food, water, energy, clothing, and building materials. It also includes the amount of land and water required to assimilate the wastes generated by that person. In other words, the ecological footprint measures a person's demand on the bio-capacity of the Earth.
