Is substance X a potential carcinogen for human cells? After generating their energy from the sun, plants pass the energy on to the primary consumers. . The four levels in this food chain are primary consumers, secondary consumers, tertiary consumers, and finally decomposers or phytoremediators. All other organisms rely on the producers' ability to photosynthesize. Plants and animals interact in feeding . Craven, JFC; (1999) Redskins in Epping Forest: John Hargrave, the Kibbo Kift . . Photosynthetic plants are the only producers that can produce food by using water and minerals from the soil, carbon dioxide from the air, and energy from sunlight in the presence of chlorophyll and other photosynthetic pigments in the photosynthetic regions such as leaves and young green tender stems. Photosynthesis allows plants to create the essential sugars and nutrients for survival. Algae, Barnacles, and Sponges. They are mostly evergreen trees with shallow roots. Instead, they rely on sources of organic carbon like plants and animal matter.
