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. Forests can be classified into different types, such as tropical rainforests, temperate forests, and boreal forests, each with unique characteristics and species. They also provide essential resources like timber, medicine, and recreational opportunities, making them vital for both ecological health and human well-being.
