What would happen if rats was eliminated from the environment

Rats account for a decent amount of biomass globally.  They are intermediate predators, eating a lot but also being eaten.  If they went extinct, they would stop eating many insects and seeds / fruits -- the former would gain significantly in population, and the latter would lose some of their pollination.  Both factors would harm the viability of at least some species of plants, by adding to plant eaters (insects) and reducing plant reproduction.  Rats' predators would also suffer if they went extinct.  The primary predators are birds of prey, such as hawks and owls.  However, other animals such as skunks, foxes, weasels, coyotes, and even wolves eat rats.  For predators in marginal environments, the loss of such a food source could drive them out of a habitat area.

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
