Microscopic organisms can affect the functioning of ecosystems as much as larger species. Researchers studied marine benthic diatoms, which are algae that grow on shallow sea bottoms. The study showed that the diversity of diatoms sets the lower boundary for ecosystem productivity. Communities with, for example, both small and large species, both low- and high-growing species, and both attached and free-moving species were the most productive.

According to research results published in the scientific journal Ecology, diverse diatom communities enhance the productivity of marine coastal zones.
