why is food web more realistic representation of nutritional patterns than a food chain?

Question

wat is the original source of engery for all organisms in a food pyramid? wat is herbivores? wat is biomass? wat is decomposer?

Answer 1

Food webs are more realistic because the web shows the many different feeding relationships while a food chain just shows one straight line possibility of what eats what. So while a food chain may show that clover was eaten by a rabbit which was eaten by a coyote, a food web would show us that the rabbit doesn't just eat clover (also grasses, corn, dandelions, ...) and rabbits aren't just eaten by coyotes (also dogs, bacteria, fleas, ...) and the clover is also eaten by mice, grasshoppers, deer, ...

Original source of energy is the sun.
Herbivores are organisms that only eat plant matter.
Biomass is the total amount of living matter in a trophic level in that ecosystem.
A decomposer is an organism that breaks down dead organic matter and absorbs the nutrients.

Answer 2

A foodstuff chain shows how each living ingredient gets its foodstuff. some animals consume plant life and a few animals consume different animals. as an occasion, an elementary foodstuff chain hyperlinks the timber & shrubs, the giraffes (that consume timber & shrubs), and the lions (that consume the giraffes). each link in this chain is foodstuff for the subsequent link. A foodstuff chain consistently starts with plant life and ends with an animal. In a foodstuff chain, potential is handed from one link to a diverse. while a herbivore eats, in basic terms a fragment of the potential (that it gets from the plant foodstuff) will become new physique mass; something of the potential is misplaced as waste or used up via the herbivore to accomplish its existence approaches (e.g., flow, digestion, reproduction). hence, while the herbivore is eaten via a carnivore, it passes in basic terms a small quantity of complete potential (that it has won) to the carnivore. Of the potential transferred from the herbivore to the carnivore, some potential would be "wasted" or "used up" via the carnivore. The carnivore then has to consume many herbivores to get sufficient potential to strengthen. foodstuff Webs coach how plant life and animals are interconnected via diverse paths. as an occasion, timber produce acorns which act as foodstuff for many mice and bugs. through fact there are various mice, the weasels and snakes have foodstuff. The bugs and the acorns additionally entice birds, skunks, and opossums. With the skunks, opossums, weasels and mice around, hawks, foxes, and owls can locate foodstuff. they're all related! hence, in an elementary rationalization. foodstuff Webs coach how plant life and animals are related in many the kind to help all of them proceed to exist. mutually as foodstuff Chains persist with in basic terms one process potential as animals locate foodstuff.

Answer 3

the food chain is usually oversimplified because most organisms have more than one food source

the food web shows more of the complexity of real world organisms
