Describe a simple food chain and the trophic levels within it

Grass -> rabbit -> Fox -> Crow -> Bacteria + FungiGrass = producer - first trophic level, uses photosynthesis to convert carbon dioxide and water to glucose Rabbit = primary consumer - second tropic level, always a herbivore or omnivore they feed on the producerFox = Secondary consumer and also predator in this food chain - third trophic level, carnivore that feeds on the primary consumer which is also the prey in this food chainCrow = scavenger - fourth trophic level, feed on dead animals from previous trophic levels Bacteria and fungi = decomposers - fifth trophic level - feed on dead and decaying organisms from previous trophic levels
