Organisms aren't equally distributed throughout the biosphere because more life is found around other things that are living. For example, you'd find more bugs on a tree than in the sand. This is because in general, living things need other living things to survive. The bugs will eat the tree and things living on the tree.
In a homogeneous mixture particles are spread evenly.
no
Diffusion
This is a nonhomogeneous mixture.
Equilibrium
In a homogeneous mixture particles are spread evenly.
it protects us from solar radiation, which are charged particles/ waves that the sun fires out in all directions. If the ozone was spread evenly all over the planet it would only be a layer 2mm thick, but it is not evenly spread. One kilogram of CFC's destroys 70,000 kilograms of ozone.
When particles separate and spread evenly throughout a mixture, it is called diffusion.
