An ecosystem is a community of living organisms (plants, animals, and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system. Energy, soil, water, and nitrogen are other essential components of an ecosystem. The sun is generally the main energy resource that flows through an ecosystem. Climate, vegetation cover, types of organisms, location, and interaction between organisms and their environment are some of the factors used to classify a type of ecosystem. Unfortunately, ecosystems are always at risk of being destroyed by natural disasters like fires, floods, storms, and volcanic eruptions at any time.

Ecosystems can be categorized into three sizes: Micro the smallest kind can be as small as a puddle, messo the mid-sized kind can be the size of a forest or even a large lake, and biome is the largest ecosystem which can be the collection of many ecosystems like an entire rainforest or even the entirety of the planet Earth. Ecosystems boundaries are not categorized by a specific lines or barriers, but rather by geographical barriers like deserts, mountains, oceans, and rivers.
