Answer:
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.
Step-by-step 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.
