The statement best compares the density among the three states of matter is '<span>Solids have the least density among the three, gases have the highest, and liquids are slightly less dense than gases but much denser than solids."</span>
The answer is Solids have the highest density among the three, gases have the lowest, and liquids are slightly less dense than solids but much denser than gases.
<u>Option-(A): </u>In an illustrated flowchart, the movement of carbon atoms through an aquatic food chain is indicated by arrows.
<u>Option-(C)-</u> An increase in the population of scavengers.
Explanation:
The ecological pyramid is comprised of different level of organisms as the energy flow occur through them in a more directed form inside the different spheres depending upon the medium for energy transmission across the given parameters or area. As, the arrow provides us with a more directed way for understanding the transmission of energy through different organisms and there respective levels inside the ecological pyramid.
While, the increase in the level of scavengers or the animals which consumes the left overs of other living beings is balanced with the addition of the secondary consumers to the aquatic ecosystem.As, it will provide equal chances and energy to the different beings inside the ecosystem.
