match each type of ecological pyramid with its description.
pyramid of energy
pyramid of numbers
pyramid of biomass
shows the relative amount of living organic matter in each trophic level of a community
shows the relative amount of energy available at each trophic level of a community
shows the relative number of individual organisms found at each trophic level of a community
6 multiple choice 1 point
roughly how much of the energy available in one trophic level of an ecosystem is passed along to the next trophic level?
50%
90%
25%
10%

Explanation:

1. The pyramid of energy shows the relative amount of energy available at each trophic level of a community. The pyramid of numbers shows the relative number of individual organisms found at each trophic level of a community. The pyramid of biomass shows the relative amount of living organic matter in each trophic level of a community.
2. In an ecosystem, roughly 10% of the energy available in one trophic level is passed along to the next trophic level. This is known as the 10 - percent rule.

Answer:

1. pyramid of energy: shows the relative amount of energy available at each trophic level of a community

pyramid of numbers: shows the relative number of individual organisms found at each trophic level of a community
pyramid of biomass: shows the relative amount of living organic matter in each trophic level of a community
