1. In two to three paragraphs, name your ecosystem, tell where it is (including state and nearest town), state its limits, discuss why defining limits is important, and include any data you collected during your study of the physical limits of the ecosystem. Explain why this ecosystem is an open system. You may include a photograph or map of your ecosystem, but these are not mandatory. Be clear, thorough, and scientifically accurate.

what bodys are there orbiting?

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.
