What occurs naturally between organisms living in an environment with limited resources.

Not all of the individuals survive or reproduce.

Explanation:

With limited resources, there are scarce food, sexual couples or land available to settle. In consequence, this is explained by the theory of Natural Selection. This theory exposes that it is a phenomenon of evolution that is defined as the differential reproduction of the genotypes of a biological population.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
