Represents the transfer of energy through a series of organisms in a community. This energy flow from one trophic level to the other is known as.. A) energy pyramid B) The Tropics C) food web D) food chain

I believe the answer is A) energy pyramid

Explanation:

It's talking about trophic levels, as opposed to individual organisms.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
