Ecology is the study of how plants and animals relate to their biological and physical environments.
Ecology is typically studied on the ecosystem level. An ecosystem is a unit formed by the interactions of all the organisms within a community of plants and animals, and their relationship to the physical environment. An ecosystem might be a mountain meadow, a pine forest, or your garden. The biological environment consists of members of the same species, competitors, parasites, symbionts, predators, mutualists, and all other organisms within the ecosystem. The weeds compete for soil nutrients, water, and light.
