Every food web has consumers—animals that gain their energy by eating plants or various other animals.
You are watching: What happens when primary and secondary consumers die
Grasshopper eating Leaf
Grasshoppers are primary consumers due to the fact that they eat plants, which space producers. Producers are the basic of the pyramid, the very first trophic level.

On a sawgrass prairie in the Florida Everglades, an alligator (Alligator mississippiensis) lazes top top the bank of a slow-moving water channel. A great egret (Ardea alba) stalks fish in the shallows. A grasshopper (Brachystola magna) chews on one aster leaf. A raccoon (Procyon lotor) digs in the dirt for freshwater mussels. These animals are quite different from one another and also live in different ways, but they have something in common: In this ecosystem, they room all consumers.Within every ecosystem, organisms communicate to move energy roughly in predictable ways. These interactions deserve to be stood for by what scientists contact a trophic pyramid. Primary producers—plants, algae, and also bacteria—make up the basic of the pyramid, the very first trophic level. With a process called photosynthesis, producers catch energy indigenous the sun and use it to create simple organic molecules, which they usage for food.Consumers constitute the upper trophic levels. Unequal producers, lock cannot do their own food. To obtain energy, they eat plants or various other animals, while part eat both.Scientists distinguish in between several type of consumers. Primary consumers make up the 2nd trophic level. Lock are additionally called herbivores. Lock eat primary producers—plants or algae—and nothing else. Because that example, a grasshopper living in the Everglades is a main consumer. Part other instances of primary consumers are white-tailed deer that forage top top prairie grasses, and also zooplankton that eat microscopic algae in the water.Next are the secondary consumers, which eat major consumers. Secondary consumers are mostly carnivores, from the Latin words an interpretation “meat eater.” In the Everglades, egrets and alligators space carnivores. Lock eat only other animals. Most carnivores, referred to as predators, hunt and also kill various other animals, yet not all carnivores space predators. Some, well-known as scavengers, feeding on animals that are already dead.Some consumers feed ~ above live pets but carry out not death them. Because that example, small arachnids referred to as ticks attach themselves to various other animals and feed on your blood, but ticks are not thought about predators. They room instead referred to as parasites.Some an additional consumers eat both plants and also animals. They are dubbed omnivores, native the Latin words that typical “eats everything.” A raccoon is an example of one omnivore; it eats plant issue such together berries and also acorns, however it additionally catches crayfish, frogs, fish, and also other little animals.Ecosystems can likewise have tertiary consumers, carnivores the eat various other carnivores. A outright eagle is an instance of a tertiary customer you could see near the coastal mangrove archipelago of the Everglades. That is diet consists of predatory fish the eat algae-eating fish, and snakes that feed top top grass-eating wetland rabbits. That is considered a “top predator” since no other pets native come the ecosystem hunt or eat it. Once a peak predator dies, the is spend by scavengers or decomposers.In addition to consumers and also the producer that support them, ecosystems have decomposers. This organisms gain their nourishment from dead essential material, such as decaying plant pipeline or dead fish the sink come the bottom the a pond.
