What cell shape might increase the surface area and decrease the volume?

Convoluted surface

Explanation:

When a cell has a convoluted surface such as it has flagella, cilia and other locomotion organs as part of its essential body structure then such cells have a high ratio of surface area to volume .

In such  conditions the surface area increases but the volume decreases . However there certain losses due to high surface area such as loss of water and dissolved nutrients

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
