First trophic level: It comprises producers which can prepare their own food … WebThe trophic level of an organism is the level it holds in a food pyramid. The sun is the source of all the energy in food chains. Green plants, usually the first level of any food chain, absorb energy from sunlight to make their food by photosynthesis. Green plants (autotrophs) are therefore known as ‘Producers’ in a food chain.

WebTrophic level is defined as the position of an organism in the food chain and ranges from a value of 1 for primary producers to 5 for marine mammals and humans. The method to determine the trophic level of a consumer is to add one level to the mean trophic level of its prey. The equation corresponding to a species trophic level calculation is WebThe next highest trophic level contains 190J.
