An ecosystem is the living organisms in a particular area, along with the non-living components of the environment.
Ecosystems can be found on a variety of scales, from a small-scale freshwater pond system to the global scale of the tropical rainforest biome.
Changes to ecosystems can lead to changes in the biotic components, which include bacteria, flora, and fauna.
Ecosystems are dependent on the abiotic components, which are the non-living elements of the environment, such as climate, temperature, water, and soil type.
The biotic components of an ecosystem, which include bacteria, flora, and fauna, have a complex relationship with the abiotic components, changing one will lead to a change in the other.
