Every organism has a unique ecosystem in which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter and a place to breed. All organisms need to adapt to their habitat to be able to survive. Animals and plants with adaptations that make them better suited for the environment will survive and reproduce better than those less suited for the environment.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

multiply it by 5 in order for you to understand i cant give an exact answer.

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.
