Because they play important roles in the environment, take the food chain for example. animals continuously convert energy all the way up until a human eats. also, decomposers are important too because the return nutrients to the ground, like mushroom, fungi, and bacteria
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.
It is a fact that nuclear energy is converted into thermal energy in the core of a nuclear reactor. This is because it is part of a power plant fission act, where nuclear energy heats up water in a nearby vicinity.
