Question

Which of the following BEST describes the levels of biodiversity?

Group of answer choices

a. Habitat loss only affects community and ecosystem diversity

b. Populations can have lots of genetic diversity, or be totally fixed at specific loci.

c. Exploitation and reduction in population size make populations less susceptible to genetic drift

d. Nutrient-poor communities have high diversity

Answer 1

Answer: a. Habit loss only affects community and ecosystem diversity.

Explanation:

There are three different levels of biodiversity - Genetic, Species, and Ecosystem diversity. Genetic diversity exhibit different genes among the different population or in different genes located in the idividual. Species diversity represents all the differences between the population of species or within a population of species. Ecosystem diversity represents all the different biological communities, habitats, and ecological processes. It also represents variations within individual ecosystems.  

Habitat loss is one of the threats of biodiversity loss. Artificial human activities and population growth is a major factor or force as a result loss of population, species, and ecosystem occur.
