What does a biomass pyramid show at each trophic level?

Biomass is a measure- ment of the amount of living organisms in an area. The biomass pyramid shows the total dry mass of organisms found at each trophic level. A pyramid of numbers gives a count of the numbers of individual organ- isms at each trophic level in an ecosystem.

What does a number pyramid tell you about an ecosystem?

A pyramid of numbers shows the total number of individual organisms at each level in the food chain of an ecosystem. An inverted pyramid of numbers can be found in an ecosystem where the community contains a few producers with a very large biomass that support a larger number of smaller consumers.

What does pyramid of biomass represent?

A pyramid of biomass shows the total biomass of the organisms involved at each trophic level of an ecosystem. There can be lower amounts of biomass at the bottom of the pyramid if the rate of primary production per unit biomass is high.

What happens to biomass at each trophic level?

In fact, only about ten per cent of the biomass is transferred from each trophic level to the next. The remaining 90 per cent is used by the trophic level to complete life processes . Biomass can be lost between stages because not all of the matter eaten by an organism is digested.

What is a trophic position?

Trophic position, sometimes called trophic level, are terms that refer to the position an organism occupies in the food web. For instance, a primary producer (anything that can make its own food) like algae or plants, would be at the base or beginning of a food web, having a trophic position of 1.

What is trophic level give an example?

A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. Trophic levels three, four and five consist of carnivores and omnivores. Carnivores are animals that survive only by eating other animals, whereas omnivores eat animals and plant material.

Is the number of trophic levels limited?

The number of trophic levels in an ecological energy pyramid is most definitely limited. As one increases in trophic level, there is less and less energy available.
