Marine Food Web: How Phytoplankton Support Ocean Life Through Photosynthesis #213622 (License: Personal Use)

Sunlight fuels photosynthesis in marine phytoplankton, the base of the oceanic food web; these microscopic organisms are consumed by zooplankton, which in turn support larger predators like whales and fish. Arrows indicate energy flow and oxygen release, highlighting the critical role of plankton in global carbon cycling and atmospheric oxygen production.

Used in educational science pages, ecology blogs, or environmental curriculum materials to explain primary productivity and trophic dynamics in marine ecosystems; matches user intent to understand ocean food chains or climate-related biological processes.
