Note: The food web is a network of food chains in an ecosystem where all organisms are interconnected to each other. … The flow of energy in a food web is always unidirectional. In a food web, the supplies of food never end. Therefore, it is more stable than the food chain.
How does food web provide stability to the ecosystem?
Food web increase the stability of an ecosystem because food web includes all interconnected food chains. … Also, food web results in the regular circulation of energy and cycling of nutrients in the ecosystem, that aids in its stability.
Why is it better to draw a food web rather than a food chain?
Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems. Energy transfer between trophic levels is inefficient—with a typical efficiency around 10%. This inefficiency limits the length of food chains.
Why is more complex food web considered more stable than a less complex one?
The more complex the community included in the model, the greater its stability in terms of both resistance to perturbation and rate of response to perturbation. This is a realistic way to model the natural world because organisms cannot avoid feedback to and from their material environment.
Why is food web important in an ecosystem?
Food webs are important tools in understanding that plants are the foundation of all ecosystems and food chains, sustaining life by providing nourishment and oxygen needed for survival and reproduction.
Why are complex ecosystems more stable?
The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases. … A food web depicts various ways in which organisms eat other organisms and obtain energy for their survival.
Are complex food webs more stable?
More complex food webs are actually less stable than shorter ones and are easiest to disrupt. Generalist species most easily invade simple food webs while specialists, capable of exploiting a restricted source of energy, are best able to invade a complex food web.
How does food web complexity affect the biodiversity of an ecosystem?
How Does Food Complexity Affect the Biodiversity of an Ecosystem? As food web complexity increases, there is less stability in the population of the different species, causing as a result, biodiversity fluctuations in a more rapid and frequent way.
