Answer:
Option A, all of the genes found within the ecosystem
Explanation:
Genetic diversity is very essential to maintain the health of the population of any species. It includes all forms of alleles with in a specific species to ensure variability. Variability is essential to allow evolution of species through mating where species with more desirable genes mate to produce healthy offspring. Sub groups with in a species can also varying set of genes thereby making a gene pool.
Hence, option A is correct
Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.
Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.
