Producers are very important for an ecosystem as they trap the solar energy received from sun through the process of photosynthesis in order to produce food for consumers. This food when consumed by other organisms leads to flow of energy from one organism to other which lie at different trophic levels of a food chain.
Producers lie at the base of an energy pyramid and thus are the initiators of the food chains.
If there would have been no producers, there would have been no food cycle/chains and thus no flow of energy and and hence no stable ecosystem.
Being extremely important for the ecosystem , producers are living being such as trees, plants, algae etc. and thus they are the most important biotic factor in an ecosystem
Three scientists are credited with the development of cell theory. Matthias Schleiden observed that all plants were made of cells; Theodor Schwann observed that all animals were also made of cells; and Rudolf Virchow observed that cells only come from other cells.
Because of the pigments. Like chlorophyll pigment is always green. Specific colors of light and reflect other colors, depending on their chemical structure.
