Hydrothermal vent mussels and shrimps Most animals rely upon biomass and bioenergy produced by plants and phytoplanktons (collectively identified as producers) by means of photosynthesis. Herbivores, as primary people, consume the plant product on to digest and take in the nutrients, while carnivores together with other animals on larger trophic levels indirectly get the nutrients by eating the herbivores or other animals which have eaten the herbivores.
