The top predators are the carnivores at the top of the food chain sequence. The term food chain refers to the sequence of events in an ecosystem, where one organism eats another and then is eaten by another organism. The first trophic level includes all green plants (primary producers), plant eaters or herbivores (primary consumers), carnivores or secondary consumers (third trophic level), and other carnivores or tertiary consumers (fourth trophic level), and so on. The second diagram shows several predators that eat the same prey.

The amount of living matter at each trophic level at any given time is known as standing crop or standing biomass and the position of organisms in a food chain sequence is referred to as trophic level. The first diagram shows one predator that eats many types of prey plus a few plants. So, in a word, an ecosystem has no waste.Īs a result, in an ecosystem, there is a definite sequence of producers and consumers, and their interactions, as well as population size, are described as trophic structure.
A food chain usually begins with a plant (which gets its energy from sunlight and nutrients from the soil). All living and dead species are potential nourishment for other organisms. A scavenger is an animal that eats dead animals. The other converts the sun’s light energy into chemical energy. See more ideas about harley bikes, custom street bikes, motorcycle harley.
