Why would a ecosystem that had a high species diversity be more productive and effective? A)

different species can complement each other in an ecosystem making it

more productive

B)

the higher the diversity, the higher the populations of all the

photosynthetic organisms

C)

animals do not need plant species so the plants are able to be more

productive without the animals interactions

D)

animals form the base of any food chain which allows many different

species of plants to survive and be more productive

the higher the diversity, the higher the populations of all the

photosynthetic organisms

Explanation:

Diversity in plant allows random mating also known as panmixia. It allows plant have equal chances of being mated too by any among them creating variations in the population. It leads to less fixed gene, reduce genetic drift leading to an increases population as some lethal gene may be lost due to recombination of gene among individual plant.

Where there is no diversity some gene becomes fixed leading to perpetuation of some traits that may be harmful in a population but diversity allows for the generation of new gene and allele frequency within a population.

answer: a. a gene that causes a specific trait.
