A forest ecosystem is a community of living organisms, including trees, plants, animals, and microorganisms, interacting with their physical environment. These ecosystems are characterized by a dense canopy of trees that provide habitat and food for various species. Forests play a crucial role in maintaining biodiversity and regulating the climate by absorbing carbon dioxide. In a forest ecosystem, different layers exist, such as the canopy, understory, and forest floor. Each layer supports unique life forms, from birds and insects in the canopy to fungi and decomposers on the forest floor. Healthy forest ecosystems are vital for clean air, water, and soil, benefiting both wildlife and humans.
