Decomposers break down dead plants and animals. They also break down the waste of other organisms. They are an important element in the food chain because they keep up a continuous flow of nutrients for the primary producers.
How is energy lost in a food chain?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. … A food chain can usually sustain no more than six energy transfers before all the energy is used up.
Are humans the ultimate predator?
Predators that exert a top-down control on organisms in their community are often considered keystone species. Humans are not considered apex predators because their diets are typically diverse, although human trophic levels increase with consumption of meat.
What is the first organism in a food chain?
Producers, also known as autotrophs, make their own food. They make up the first level of every food chain. Autotrophs are usually plants or one-celled organisms. Nearly all autotrophs use a process called photosynthesis to create “food” (a nutrient called glucose) from sunlight, carbon dioxide, and water.

What is food chain give two examples?
A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass.
