compare the effects of increasing both genetic diversity and species richness on an ecosystem.

a. both an increased genetic diversity and increased species richness are good for the ecosystem because they provide variety within a species and an abundance of species.

b. neither increasing genetic diversity nor increased species richness are good for the ecosystem because they provide variety within the species and an abundance of species.

c. an increase in genetic diversity is not good for the ecosystem because it provides variety within a species. increased species richness is good for the ecosystem because there is an abundance of species.

d. an increase in genetic diversity is good for the ecosystem because it provides variety within a species. increased species richness is not good for the ecosystem because there is an abundance of species.

Answer is Option A: Both an increased genetic diversity and increased species richness are good for the ecosystem because they provide variety within a species and an abundance of species.

Explanation:

Species richness refers to the number of species in a particular area. Several factors affect Species richness like geological, biological and environmental factors.  

Genetic diversity is important because it maintains the health of a population. There are greater number of alleles included in that species and they have fight against diseases, pests etc. They would be able to adapt better to the environmental changes. Thus, it boosts productivity of an ecosystem. The variety of species would play an important role in the ecosystem.

Both genetic diversity and species richness are related to each other and both are important.

answer; the negotiator was not in full control of his or her actions and hence should not be held responsible;

answer; the smaller of the two reciprocal products of translocated chromosomes is lost; after several cell divisions, only the larger of the two translocated chromosomes remains,its reciprocal is lost;
