Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow.

Here, vultures gobble up the bodies of cows that have been left lying around.
A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms.
Fungi are important decomposers, especially in forests.
Finally, the hyena has special acids in its stomach.
Fish called remoras attach themselves to other sea creatures, such as sharks. Also on the list of decomposers are flies, mites, spiders, slugs, and snails, to name a few.
Sarah Appleton, National Geographic Society In fact, more than 40 percent of plastic is used only once before it is thrown away, where it lingers in the environment for a long, long time.
A producer would be organisms that photosynthesize and a consumer is predator.
Humus is dark, organic material that forms in soil when plant and animal matter decays.
Spiders, worms, and other Sharks patrol the ocean looking for dead fish to feed on. Help your class explore food chains and webs with these resources.Plastic is ubiquitous in our everyday lives. A vulture might feed on a dead zebra. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.While decomposers break down dead, organic materials, detritivores—like millipedes, earthworms, and termites—eat dead organisms and wastes.When you have an empty bottle, do you recycle it so the plastic or glass can be used again?
Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers are organisms that can make their own food. When plants drop leaves, twigs, and other material to the ground, it piles up.A photo of a dead ant killed by a parasitic fungus. From this position, they eat up what the shark leaves.Flies, slugs, beetles, ants, and worms are very important decomposers.
The dead bodies of plants and animals are a rich source of organic matter that provides nutrition for many insects called saprophages (from the Greek words "sapros" meaning rotten and "phagein" the verb to eat or devour.Insects adapted to this lifestyle are an essential part of the biosphere because they help recycle dead organic matter. © 1996 - 2020 National Geographic Society.

Decomposer Definition. They're regarded as the foundation of almost all ecosystems. The ants are decomposers because they eat old food scraps so they can decompose. Clint Parks
Decomposers are those who eat dead materials and turn them to organic matter.
Some leave droppings that provide food for other decomposers.The American burying beetle buries dead animals and then eats them. Gina Borgia, National Geographic Society
They will eat the rest of the dead body!After the larger scavengers finish, smaller creatures take over. (singular: bacterium) single-celled organisms found in every ecosystem on Earth.plants' green pigment that is essential to photosynthesis.organism on the food chain that depends on autotrophs (producers) or other consumers for food, nutrition, and energy.community and interactions of living and nonliving things in an area. A male and female bury a dead animal, such as a mouse. The Rights Holder for media is the person or group credited.
and its Licensors In fact, more than 40 percent of plastic is used only once before it is thrown away, where it lingers in the environment for a long, long time. Soil needs moisture, air, and nutrients to be healthy.
They must eat other organisms for their food.Fungi are tiny threadlike structures that look like spaghetti. Other decomposers are big enough to see without a microscope. A food chain outlines who eats whom.
