The red squirrel is a species of tree squirrel that can be found in parts of Europe and Asia. In an experiment, a researcher introduced small populations of red squirrels to two different ecosystems at the same time. The graph below shows the red squirrel population in both ecosystems over three years. Which explanation(s) could account for the different carrying capacities of the two ecosystems?

answer; i believe the correct answer is (a)0

your spelling is a little off : ]

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.
