POSSIBLE P Why is an energy pyramid smaller at the top than at the base?
the animals at the top are not good at hunting so there are less of them
The amount of energy available to top predators is greater than the amount of energy available to produce
The energy available to top predators decreases as you move up the pyramid so it limits the size of the
predator population
O the mass of all the predators at the top is greater than all the plants at the bottom

explanation:

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.
