The relationship between heterotrophs and autotrophs breaks down into a sequence of energy and consumption. There are many types of heterotrophs, but in a common system, plants create carbon matter and energy from the resources around them. Herbivores then eat these plants, extracting energy from ...
In graziing food chains, green plants (producers) constitute the first trophic level. In detritus food chain, decomposers or detritivores constitute the first trophic level. They feed on detritus (dead decaying organic matter).
Ecosystem biota — the living organisms that contribute to the system along with abiotic elements such as minerals and sunlight — are often categorized based on their method of obtaining energy. One scheme calls photosynthetic organisms such as green plants "producers." The animals that directly eat...
Usually, a typical ecosystem contains producers, primary consumers (herbivores), secondary and tertiary consumers (mostly omnivores and carnivores), scavengers, and decomposers. Ecosystem is formed if these components, which encompass the energy cycling, are present in a particular place. Organisms will ...
