Explain why the ecosystem is a system. Use examples from the article to support your explanation.

An ecosystem is defined as a biological system which is composed of living organisms and a physical environment where they coexist and are related, it is a system since this is by definition a complex object in which its parts are related to at least one component In the case of ecosystems, each species can be related to others, such as their food, the place where their young grow, or the relationship with other species such as symbiosis.

Like all ecosystems, forests consist of many interacting parts. They include living organisms such as plants, animals, and fungi. Forests also include non-living components that these organisms depend on, such as the soil and climate. As stated in the article, one change, such as pollution, can cause a ripple effect through the ecosystem. Dying lichens are one of the earliest signs of pollution. In turn, the loss of the lichens can cause a decline in species that rely on the lichens for survival.
