Do Zooplankton Produce Oxygen?

Phytoplanktons are photosynthetic and thus are extremely important for oxygen release. Zooplanktons only take in oxygen and do not produce it. Phytoplanktons obtain their energy via photosynthesis by utilizing inorganic minerals. Zooplanktons obtain their energy by feeding on phytoplankton.

What does zooplankton produce?

Zooplankton and other small marine creatures eat phytoplankton and then become food for fish, crustaceans, and other larger species. Phytoplankton make their energy through photosynthesis, the process of using chlorophyll and sunlight to create energy.

Does zooplankton use oxygen?

Despite extraordinary hypoxia tolerance, many zooplankton live near their physiological limits and respond to slight (≤1%) changes in oxygen.
