Quick Answer: Which of the following is a more accurate representation of energy and nutritional relationships in an ecosystem?

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. … A trophic level is each step in a food chain or food web.

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

The Food Web shows more of the interactions between the organisms of the ecosystem and the trophic levels included from Producers to Primary/Secondary Consumers up through the Tertiary Consumers. While a food Chain is more of a linear representation of a specific line of interaction within the greater Food Web.

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 …

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.

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 a more detailed and accurate depiction of an ecosystem?

Why is a food web a more accurate depiction of nature than a food chain or pyramid? Explanation: It’s more realistic due to the fact you can add more organisms into the mix, and show how they interact with each other in an ecosystem.

Are food chains the most accurate model of an ecosystem?

Food webs are a more accurate representation of the structure and dynamics of an ecosystem. Food chains are easier to model and use for experimental studies. … The producers pass their energy to the various trophic levels of consumers.

Why are pyramids of organisms number not an accurate representation of ecological feeding relationships?

A pyramid of numbers shows the total number of individual organisms at each level in the food chain of an ecosystem. A pyramid of numbers does not always have a regular pyramid shape because it does not take into account the biomass of the organisms.
