construct a food Web using the following organisms :green plants, snake, owl, peacock, frog, rabbit, grasshopper
Answers
Answer:
All processes in this world, whether living or non-living, need energy. Living organisms are capable of producing energy or getting it through predation. They need this energy to maintain cells and tissues. It is also required for supporting voluntary and involuntary actions of the human body and other multiple processes within the body like reproduction, cell division, metabolism, digestion, circulation, excretion, and much more.
The ultimate source of energy on Earth is the Sun. No energy can be produced without the sun. All living beings, especially plants capture solar energy and utilise it for their food production. This process is called photosynthesis.
What is Food Web?
There are unique interactions and relationships which are involved in the transportation of energy. The energy, once produced and captured, is distributed throughout the various living organisms. This transfer of energy is termed as the food web.
What is the Food Chain?
A food chain is a network of links in a food web. Here, the producers are consumed by the predators-primary and secondary consumers and then the detritivores and finally by decomposers. When many such individual food chains occur in an ecosystem, it is known as Food Web.
A food chain shows a direct transfer of energy between organisms. As every organism can feed on multiple things, a food web is a much more realistic and simplified method of transferring energy in an ecosystem.
Both food chains and food webs are similar to each other, but they are not the same. We will explore the differences here.
A food chain presents a unique, connected path of energy flow in an ecosystem, whereas the food web explains how food chains overlap. Both food chains and food webs, shares three types of organisms in a food chain: producers, consumers and decomposers.

Producers
Organisms that can synthesize their own food and usually serve as the foundation for all food chains. For example – plants, algae and few species of bacteria. They prepare their own food by converting sunlight into chemical energy and this process is called photosynthesis. They use energy from the sunlight for converting carbon dioxide into simple glucose which is easily broken down to produce energy. This energy is then stored in the form of sugars for later use.
