Detailed Solution
Download Solution PDFThe correct answer is 10%.Key Points
- The term "trophic level transfer efficiency" is the average amount of organic matter that is transferred from one trophic level to the next.
- This value is usually around 10%, meaning that only 10% of the organic matter from one level is transferred to the next level.
- Because energy is lost as metabolic heat when animals from one trophic level are consumed by species from the next, energy declines as it goes up the trophic levels.
Additional Information
- The food chain is a straight line made up of creatures in which energy and nutrients are passed from one to the next.
- When one creature eats another, this happens.
- The decomposer organism comes at the end of the chain, having started with the producer organism.
