. The pyramid of mass demonstrates that ______

a) the same number of organisms is at the top as at the base of the pyramid
b) mass is gained as a food chain progresses
c) at each link in a food chain, mass is lost
d) the mass of the producers in a community equals the mass of the consumers
e) the total weight of the secondary consumers is more than the total weight of the producers

C

I agree.

thanks ms sue

You're welcome, Pam.

I agree. Eat plants.

To determine the correct answer, let's break down the options and explain how we can arrive at the answer.

a) The same number of organisms is at the top as at the base of the pyramid: This statement is not accurate. In a pyramid of mass, the number of organisms typically decreases as you move up the pyramid.

b) Mass is gained as a food chain progresses: This statement is also incorrect. In a pyramid of mass, as we move up the food chain, mass is usually lost in each successive trophic level.

c) At each link in a food chain, mass is lost: This statement is correct. In a food chain, energy is transferred from one trophic level to another. At each trophic level, some energy is used by the organisms for their own biological processes, resulting in a loss of mass as you move up the pyramid.

d) The mass of the producers in a community equals the mass of the consumers: This statement is not accurate. Producers (autotrophs) generally have a larger mass than the consumers (heterotrophs).

e) The total weight of the secondary consumers is more than the total weight of the producers: This statement is also incorrect. In a typical pyramid of mass, the total weight of the producers at the base is greater than the total weight of the consumers at the higher trophic levels.

Based on the explanations above, the correct answer is c) At each link in a food chain, mass is lost.
