Foraminifera are primarily heterotrophic organisms, meaning they obtain their nutrients by consuming organic matter and other microorganisms. However, some foraminifera have symbiotic relationships with photosynthetic algae, allowing them to derive some energy from photosynthesis. These symbiotic foraminifera can be found in well-lit, shallow marine environments where sunlight penetrates. Overall, while not strictly autotrophic, certain foraminifera can harness autotrophic processes through their symbiotic partners.
