Food Chain

• A food chain is the sequence of events in an ecosystem in which one live organism consumes another, and that organism is then consumed by another larger organism.
• A food chain is formed by the transfer of nutrients and energy from one creature to another at different trophic levels.
• The food chain also illustrates how living species feed or interact with one another.
• Trophic level refers to the successive phases of a food chain, beginning with producers at the bottom and progressing through primary, secondary, and tertiary consumers.
• A trophic level is any level in a food chain.

Food Web:

• A food web is made up of several interrelated food chains. A food web is comparable to a food chain, however the food web is significantly larger.
• Occasionally, a single organism is consumed by a large number of predators, or it consumes a number of other organisms.
• As a result, multiple trophic levels become intertwined. The food chain fails to accurately depict the flow of energy.
• However, because it depicts the interactions of various creatures, the food web is capable of displaying the accurate representation of energy flow.
