Zooplankton: Tiny Aquatic Organisms That Sustain Ocean Food Webs #320242 (License: Personal Use)

This educational illustration depicts six representative zooplankton organisms-including a copepod, a cladoceran (like Daphnia), a rotifer, a protozoan, a larval crustacean, and a chaetognath-arranged in a circular composition. Each organism is rendered with anatomical detail to highlight key features like appendages, body segmentation, and feeding structures. The image serves as a visual aid for understanding microscopic marine and freshwater consumers that form the second trophic level in aquatic ecosystems.

Used in biology textbooks, marine science websites, environmental education modules, and museum exhibits to introduce learners to planktonic life. Matches user intent for academic study,科普 content, or curriculum development on aquatic ecology.
