Explanation:
Answer:
Tortoises with better adaptations in shell shape and leg length were selected to exploit the food resources on each island and, thus, they were capable of having more offspring.
Explanation:
Natural selection can be defined as the process of differential survival and reproduction in a given environment due to differences in their phenotypic traits. Thus, these phenotypic traits are selected to be better adapted to their environment. As a consequence of natural selection, organisms evolve by changing their phenotype frequencies over many generations. In this case, phenotypic differences are expressed as variations in shell shape and leg length, which are adaptive traits that were selected on each island.
Answer:
When many different species live in an environment, the environment has high<em> biodiversity</em>. If the number of predators increase in an area, the immediate effect will be a<em> unstable ecosystem (</em><em>decrease in the population of prey</em>.)
Explanation:
In ecology, biodiversity can be described as the different plants and animals which live in a habitat. If a habitat has many kind of different species, then the habitat or ecosystem will have a wide biodiversity. The wider the biodiversity, the more stable an ecosystem will be.
If the number of predators will increase then the ecosystem will become unstable. There will be more competition for resources.
