microherbivore

A microherbivore is an animal that feeds primarily on microscopic plant matter. This category includes a wide range of organisms, from single-celled protozoa to small invertebrates. Their diet typically consists of algae, bacteria, and other microscopic plant life found in aquatic environments or on moist surfaces.

Microherbivores play a crucial role in many ecosystems. By consuming large quantities of microscopic producers, they help regulate the population sizes of these organisms and prevent overgrowth. This grazing activity also contributes to nutrient cycling within the ecosystem, as waste products are released and nutrients become available for other organisms. Many microherbivores are themselves a food source for larger animals, forming an important link in the food chain.

Examples of microherbivores include certain species of zooplankton, such as rotifers and some copepods, which graze on phytoplankton. In freshwater and marine environments, microscopic snails and some larval stages of larger invertebrates also fit this description. On land, certain small invertebrates living in soil or on plant surfaces may also be considered microherbivores if their diet is predominantly microscopic. Their small size and specialized diet allow them to occupy ecological niches that are inaccessible to larger herbivores.
