The distribution of species in British woodland is affected by a number of biotic and abiotic factors. Herbivores eat plant material and carnivores eat herbivores, gaining some energy from the foods they consume. Only a fraction of the energy consumed at a lower level is carried to the next level. At the top of the food chain, predators prey on herbivores or other predators. (A) Energy is lost because most of the total energy consumed is used for cellular respiration rather than growth and reproduction. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries.

What other name could you give to a primary consumer? Herbivores nourish plants that take energy from the sun. Nu Primary producer of an ecosystem is . Primary consumers are usually herbivores that feed on autotrophic plants, which produce their own food through photosynthesis. Foxes, wolves, lions, and sharks are types of carnivores. What is the likely cause of this in freshwater ecosystems? Dugong is the other species of manatee. For example, cows and goats have incredibly complex digestive systems. One prominent consumer, for instance, is a grasshopper that resides in the Everglades. d. The least amount of energy is available at the top of a food chain. Producers are those who prepare their own food, so all green plants who prepare heir own food are considered as Producers. You can find dugong in our neighbor country which is Australia. Primary producers are the foundation of an ecosystem. (C) ones that use nitrogen-containing compounds as an electron acceptor. Consumers in a forest ecosystem are also called heterotrophs because they cannot produce their own "food" as producers do. 1. . 4.
