Algae and microinvertebrates are a vital component of freshwater and marine food webs. Algae are small plant-like organisms that produce oxygen and sugars at the base of the food web. Microinvertebrates are small animals that consume algae. The algae and microinvertebrates found in the water column are called “phytoplankton” and “zooplankton,” respectively. Algae that grow attached to submerged structures such as rocks, docks, sediments or aquatic plants, are called “periphyton.”
