Algae are producers. This means they produce their own energy, usually through photosynthesis. Like most producers, algae turn sunlight, carbon dioxide and water into glucose for energy.
Green plants and algae occupy the producer level because they can use the energy of the sun, plus carbon dioxide and water, to produce glucose and oxygen. The next trophic level is primary consumer or herbivore. These are organisms that gain food energy by eating the producers. An example is a caterpillar consuming leaves or a rabbit feeding on crops. The next trophic level is the secondary consumer.
