EVERYDAY SCIENCE

Detailed explanation-1: -Producers (autotrophs) are typically plants or algae. Consumers (heterotrophs) are species that cannot manufacture their own food and need to consume other organisms. More items

Detailed explanation-2: -Secondary consumers, at trophic level three, are carnivores and omnivores, which obtain at least part of their nutrients from the tissue of herbivores. This includes animals and carnivorous plants that feed on herbivorous insects (insectivores).

Detailed explanation-3: -All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables.

Detailed explanation-4: -They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes. Fungi are important decomposers, especially in forests.

Detailed explanation-5: -Since so little energy is available for the next level of consumers, food chains generally consist of only a maximum of three or four steps. The loss of energy at each step is so great that very little usable energy remains after three or four trophic levels to be transferred or consumed.
