Understanding Zooplankton
Zooplankton are tiny organisms that drift in water bodies. They play a crucial role in aquatic ecosystems.
What Is Zooplankton?
Zooplankton includes microscopic animals like copepods, rotifers, and krill. These creatures vary in size from less than 1 millimeter to several centimeters. Zooplankton are heterotrophic, meaning they rely on consuming phytoplankton, bacteria, and detritus for energy. Their diverse species contribute to the food web by serving as food for larger aquatic creatures, including fish and whales.
Importance of Zooplankton in Aquatic Ecosystems
Zooplankton hold significant importance in maintaining balanced aquatic ecosystems.
- Nutrient Cycling: Zooplankton help recycle nutrients, supporting the growth of phytoplankton. This contributes to the overall health of aquatic systems.
