<span>The cells with the small size have the surface area and volume that are proportional to each other such that this aids with the efficiency of the cell's absorption of nutrients and defecation process of the wastes. Hence, the small dimensions of cells is more efficient than the large ones.</span>
Coevolution is the name given to a long term change that takes place in two species because of their close interactions with one another.
Coevolution occurs when the evolution of two or more species mutually depends on each other or influences each other due to their close ecological interactions. Coevolution can create interactions such as predators and prey, parasites and hosts, mutualism and competition.
An example of coevolution is mutualistic interaction between flowering plants and associated pollinators (such as insects) which have ecological interaction and mutually depend on one another. This species are believed to evolve together or probably came together after some time and are mutually adapted. Their interaction is as a result of coevolutionary process.
