24. A wolf is a KEYSTONE species. Explain how the wolf indirectly affects the population numbers of plants.

Wolves have both direct and indirect effects on their ecosystem; their prey is harmed, their prey is significantly impacted by the species of plants and animals below them, and so on down the chain. This top-down impact cascade occurs alongside bottom-up effects, all within the same ecosystem.

Option A

Explanation:

The heterozygous allele can be defined as the condition in which the organism has two different alleles of the gene.

It is represented as Rr, means a capital letter and a small letter. This hows that the organism has one dominant gene and one recessive gene in it.

This dominant and recessive condition decides the genotype and phenotype of organism.
