Elephants, who are important grazers, are instrumental in transforming woodlands into grasslands. This has a tremendous impact on other species that depend on the grass for their survival. The significance of the elephant in this example is B. keystone species.
Answer:
The stored energy in the wood is chemical energy, meaning that it can be released by a chemical reaction (burning). It's closely related to those fossil fuel energies, because the chemical energy was formed by photosynthesis, using energy from sunlight as the input.
Explanation:
1. These four factors can effect ways evolution occur:
<span>1.) Mutation
2.) selection
3.) Gene Flow
4.) Genetic Drift
2. </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.
Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.
In population genetics, gene flow is the transfer of alleles or genes from one population to another.
<span>Genetic drift is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>
