Primary producers make up the first trophic level. The rest of the trophic levels are made up of consumers, also known as heterotrophs; heterotrophs cannot produce their own food, so they must consume other organisms to acquire nutrition. The first trophic level contains the greatest number of organisms and is comprised mainly of plants. The organisms in this layer are called primary producers.Hence the correct answer is (D).
