Why are there always more members on the lower trophic levels than the higher trophic levels? The members of the lower trophic levels are always small in size so there can be more of them.
The members of the lower trophic levels pass on all of their energy to the next trophic level.
As energy moves from one trophic level to the next, less and less energy is available for the next level limiting the number on the next level.
As energy moves from one trophic level to the next, more and more energy is available for the next level limiting the number on the next level.

This is so important ugh its 25 points

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.

Error analysis: what might be the reason that some of your percentages didn't exactly match your predicted results? gametes aren't responsible for inheritance. mice don't have large litters, so the sample size was not large enough. the wrong type of mice were used.
