There may be additional carnivorous consumers here which would be called tertiary and quaternary. They take in energy from the sun and make their own food, and are called autotrophs. can be added together to make a food web. For example cats, dogs and lions. At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food. called a primary consumer. A trophic level refers to a level or a position in a food chain, a food web, or an ecological pyramid. All other food chains in an ecosystem can be added together to make a food web. Feed on dead and decaying organisms, and on the undigested parts of plant and animal matter in faeces. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The width of each bar represents the units of energy available within each trophic level; the height is always the same. They are either secondary or tertiary consumers. Examples include green plants. The organisms that make up the base level of the pyramid vary from community to community.In terrestrial communities, multicellular plants generally form the base of the pyramid, whereas in freshwater lakes a combination of multicellular plants and single-celled algae constitute the first trophic level. All organisms at the first trophic level ______. These organisms are known as autotrophs.
