The solar radiation from the Sun provides the input of energy which is used by primary producers, also known as autotrophs. window.addEventListener('test', hike, aid); The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other. These feeding levels are called trophic levels. Scenario 1: Reintroduction of experimental populations of wolves.
