What Is a Pond Ecosystem?

The abiotic components are formed by the mixtures of organic and inorganic materials. Basic abiotic components are water, oxygen, calcium, carbon dioxide, salts and nitrogen. Many organisms get their nourishment from the abiotic components.

Biotic components of a pond ecosystem include producers, consumers and decomposers. The producers consist of macrophytes and phytoplanktons. The consumers are heterotrophs, meaning they depend on other organisms for their nutrients. Most decomposers are saprophytes, but some are parasites.
