Best answer: Which term is more accurate representation of the relationship between organisms in an ecosystem food chain or food web?


What is the term for all the food chain relationships in an ecosystem?

There are a great many feeding relationships in any ecosystem, but energy always flows from primary producers to various consumers. These feeding relationships are represented by food chains and food webs. … The network of feeding interactions is called a food web.

Which is a more accurate representation of the feeding relationships in an ecosystem?

Pyramids of energy are the most accurate representation of feeding relationships in a community, providing information about the amount of energy flowing through each trophic level over a set period of time.

What is the relationship between organisms in a food chain to their environment?

Feeding relationships show what organisms eat or are eaten by others and through this the levels of organisation in an ecosystem. These can be shown in food chains , which add together to make food webs for a habitat .

Which is more accurate food chain or food web?

A food chain is a single series of organisms in which each plant or animal depends on the organism above or below it. … For that reason, the term food web is more accurate than is food chain.

What is the relationship between food chain and food web?

A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels.

What is the most accurate display of feeding relationships?

Why is a food web a more accurate representation of the feeding relationships in an ecosystem than a food chain? A food web shows many different kinds of species and their individual webs, while a food chain shows only the chain of one dominant carnivore.

Which is the most accurate portrayal of what organisms eat in an ecosystem?

Food chains are linear aspects of food webs that describe the succession of organisms consuming one another at defined trophic levels. Food webs are a more accurate representation of the structure and dynamics of an ecosystem.

Which diagram is more accurate at representing the flow of energy in an ecosystem?

A pyramid of biomass is a more accurate representation of the flow of energy through a food chain than a pyramid of numbers, but seasonal variations in the rate of turnover of the organisms at a particular level may result in higher or lower values for the amount of biomass sampled at a particular time than the average …

What shows the relationship between all organisms in an ecosystem?

Food chains and food webs are diagrams that represent the feeding relationships from producers to consumers to decomposers. They show who eats whom. In this way, they model how energy and matter move through ecosystems. A food chain represents a single pathway through which energy and matter flow through an ecosystem.

Why are pyramids of organism numbers not an accurate representation of ecological feeding relationships?

A pyramid of numbers does not always have a regular pyramid shape because it does not take into account the biomass of the organisms. … For any food chain, producers store the most energy and the energy stored decreases at each level, giving a regular pyramid of energy.

What is the graphical representation of feeding relationship?

Ecological pyramid is a graphical representation in the form of a pyramid showing the feeding relationship of groups of organisms. It is often represented in a way that the producers are at the bottom level and then proceeds through the various trophic levels in which the highest is on top.
