When does expiremental growth of a population stop?

The exponential growth of a population stops when some aspect of its environment causes it to no longer be sustainable.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
