Question

What are food chains and food webs? Why are smaller food chains better? What is \[10\% \] flow?

Answer 1

Hint: Ecosystems are the structural and functional units of ecology in which living species interact with one another and with their surroundings. An ecosystem, in other terms, is a series of interactions between species and their surroundings.
Functions:
It's also in charge of nutrition cycling between biotic and abiotic components.
It helps to keep the ecosystem's various trophic levels in check.
Minerals are cycled through the biosphere.

Complete answer:
Part A:
Food chain- A food chain is the sequence of events in an ecosystem in which one living organism eats another organism, which is then eaten by a larger organism. A food chain is the movement of nutrients and energy from one creature to another at different trophic levels.
The feeding pattern or relationship between living species is also explained by the food chain. In a food chain, the trophic level refers to the order in which producers, primary, secondary, and tertiary consumers appear, with producers at the bottom and primary, secondary, and tertiary consumers at the top. The lowest trophic level in a food chain is the trophic level.
Food web- A food web is made up of several interrelated food chains. A food web is similar to a food chain, with the exception that a food web is much larger. A single organism is occasionally consumed by a large number of predators, or it consumes multiple other organisms. As a result, multiple trophic levels become intertwined. Because it depicts the interconnections between different organisms, the food web is able to provide the accurate representation of energy flow.
Part B:
Smaller food chains are better because the energy loss at each trophic level is so great that after three or four trophic levels, there is very little usable energy remaining to support the next trophic level. As a result, the reduced size provides additional stability.
Part C:
According to the \[10\% \] rule, only roughly ten percent of the transferred organic food energy is retained as meat during the transition from one trophic level to the next higher level. The rest is lost during transfer, broken down during respiration, or lost through incomplete digestion at a higher trophic level.

Note:

The flow of energy is depicted as a linear stream.	A plethora of networks depicting energy flow.
An organism with a higher trophic level feeds on a lower trophic level creature.	A higher trophic level organism has more access to lower trophic level organisms.
It has little effect on organisms' adaptation or competitiveness.	It has a role in increasing an organism's adaptability and competitiveness.
