Why might the relationship between Disturbance and Species Composition be MORE IMPORTANT than Species Richness to a Conservation Biologist?

Expert Solution

Species richness means the total number of species present in a community. Consider in a community 1 there are around 12 types of species present and in community 2 , 8 type of species are present. These species may belong to different trophic level or few of them to same trophic level . Also some of them share their niche.

Disturbance i.e, an event such as storm, fire, flood ,drought ,overgrazing or human activity that changes a community by removing organisms from it or altering resourc availability.

If there is no disturbance , there will be more competition among organism for common resources . This will result in competitive exclusion of the species.

For a conservationist species richness is not much important because if in a community species richness is more but less disturbance it will give rise to competition finally resulting in extinction of species.

But if in a community , species richness is less but disturbance is more than population of competing species will be checked regularly so less extinction

Given what we know about the relationship between genes, chromosomes, and DNA, why can more than one allele of a gene be present in an indívidual? Group of answer choices Because recessive alleles need to be in the presence of another recessive to show their phenotype This cannot happen; there can be many alleles for a gene, but most organisms will carry only one of them Most eukaryotic organisms have at least 2 sets of homologous chromosomes Due to blending...
