If a group of species lived together in a small area, the carrying capacity of that area would probably collapse quickly? ? k selected or r selected

The answer is K-selected.

The population size of K-selected species is fairly constant in time, unlike the population size of r-selected species. r-selected species are usually bellow carrying capacity and the population size is density independent. On the contrary, K-selected species are usually near or at carrying capacity and the population size is density dependent.

Holozoic nutrition refers to the regular animal nutrition mode whereas saprophytic nutrition refers to the nutrition mode of fungi and bacteria.
