Decomposer Decomposers eat all of the dead stuff in the environment and recycle the nutrients back into the ground. Primary producers are green plants, for the most part, those that take energy from the sun and convert it into forms of stored energy through the process of photosynthesis. The prairie dogs are eaten by coyotes, which are the secondary consumers. https://www.exploringnature.org/db/view/American-Prairie-Food-Web A decrease in primary consumers would lead to a decrease in secondary consumers that rely on the primary consumers and food, and a decrease in secondary consumers would lead to a decrease in tertiary consumers that rely on the secondary consumers as food. Next are the secondary consumers, which eat primary consumers. Unlike producers, consumers cannot make their own energy and must obtain it by consuming producers, and they are called heterotrophs. © 2020 Science Trends LLC. A.

Tertiary consumers are those that eat either primary consumers or secondary consumers (some of them may even eat primary producers as well, like the omnivorous brown bear which eats plant material in addition to meat). If the top predators move to a different ecosystem, the majority of the primary consumers and all of the secondary consumers would have access to increase their populations rapidly. The Scavengers – the coyotes and insects. Biotic factors- autotrophs, heterotrophs, producers, primary and secondary consumers, and the tertiary consumers Abiotic factors- climate, parental material and soil, topography, and natural disturbances Density-dependent factors- overcrowding of cyotes Density-independent factors- natural disasters like prairie fires and human interactions These are black-tailed prairie dog which are now an endangered species.
