Moving through trophic levels a. energy decreases b. entropy increases c. biomass decreases d. all of the above

The correct answer is A) Energy decreases.

Trophic level is a hierarchical level within an ecosystem that comprises of organisms having same functions within a food chain and have same nutritional relationships with respect to the source of energy.

For instance, producers form the first trophic level and all producers synthesize their food through photosynthesis.

As per the 10% law of energy transfer, transfer of energy from one trophic level to the next ( like from producers to primary consumers) is 10% and the rest 90% of the energy is utilized in various metabolic processes and released as heat in the atmosphere.

Thus, energy decreases as we move through different trophic levels.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

cell division is not regulated in tumor cells.
