Question

Scientists use different types of models to analyze the structure of ecosystems. Which characteristic is seen in a biomass pyramid, but not in a numbers pyramid?a) the total number of trophic levels in an ecosystemb) living matter found at each trophic level in an ecosystemc) energy available at each trophic level in an ecosystemd) organisms found at each trophic level in an ecosystem

Answer 1

Answer:

b) living matter found at each trophic level in an ecosystem

Explanation:

A biomass is the overall mass that comprise of living and precedently-living individual organism in a trophic level; ecosystems possess a distinctive level of biomass at every trophic level.

A numbers pyramid gives a graphical structure that gives the amount of organisms at every trophic stage. It is an upward pyramid such that in an ecosystem, the producers total population is of the highest number when compared to other trophic levels.

The correct answer among the options is "living matter found at each trophic level in an ecosystem".

The living matter located at each and every stage of the trophic level in an ecosystem is observed in a biomass pyramid and not in the numbers pyramid.

A biomass pyramid also indicates the measure of organic matter found in a living organism.
