An ecosystem, according to Smith (1970) is “a functional unit with recognizable boundaries and an internal homogeneity”.

How are matter and Energy conserved in an ecosystem?

In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled. Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, disruptive events.

Who are the producers and consumers of an ecosystem?

Producers include all autotrophs such as plants. They are called autotrophs as they can produce food through the process of photosynthesis. Consequently, all other organisms higher up on the food chain rely on producers for food. Consumers or heterotrophs are organisms that depend on other organisms for food.
