Four major components of biodiversity are:
1. Genetic diversity - refers to the genetic variation that occurs among members of the same species.
2. Species diversity - (taxonomic diversity) refers to the variety of species or other taxonomic groups in an ecosystem
3. Ecosystem diversity - refers to the variety of biological communities found on earth. With ecosystem diversity, its two levels are generally considered, which are communities and ecosystems.
4. Functional diversity - refers to the variety of biological processes, function or characteristics of a particular ecosystem.
Net primary productivity (NPP) can be defined as the amount of energy made available by plants to animals, only at the herbivore leve. The NPP of an ecosystem depends on different factors such as the levels of heat, moisture, nutrients available, competition..If the NPP is low (little available food) than animals sparse (have to move to find it).
Answer:
B) Different food production practices use resources like WATER and chemicals like pesticides which negatively impact the environment.
Explanation:
Animals and plants are meant to be eaten so even if humans eat them, as long as we don't overhunt, they will always reproduce. Chemicals are unnatural/man made sources, so the environment doesn't know how to restore itself
