Question

which of the following best describes genetic diversity? a. the variety of ecosystems within a region b. the overall number of organisms in an ecosystem c. the variety of different species within a particular area d. the variety of genes within a population of a species which of the following is a consequence of habitat destruction? a. enhanced ecosystem services b. increased species diversity c. loss of biodiversity d. improved ecological resilience what role does biodiversity play in maintaining ecosystem stability? a. it reduces the number of species in an ecosystem b. it promotes uniformity among species c. it eliminates competition among species d. it enhances the ability of ecosystems to withstand changes

Explanation:

1. Genetic diversity refers to the variety of genes within a population of a species. It's not about ecosystems, total organism numbers, or species - variety in an area.
2. Habitat destruction leads to the loss of biodiversity as it removes the living spaces of many species, disrupting ecosystems.
3. Biodiversity enhances the ability of ecosystems to withstand changes. More species mean more functional redundancy and a greater chance of ecosystem stability.

Answer:

1. d. The variety of genes within a population of a species
2. c. Loss of biodiversity
3. d. It enhances the ability of ecosystems to withstand changes
