On average sea turtles lay about 110 eggs in a clutch however only a fraction of the baby turtles make it to the ocean then an even smaller number have offspring of their own

TRue

Explanation:

The number of eggs per nest is called a clutch and it has been seen to vary among species. Turtles that live on water can lay more than one clutch in a nesting season. In most cases, the turtles do lay over 110 eggs per nest, two to eight nests a season.

When these eggs numbering over a hundred are laid, and only a small fraction of the offspring from those eggs make it to the ocean, with a few of these ending up with offspring of their own, then overpopulation has set in.  

The given statement is true.

Explanation:

As the sea turtles lay eggs on the seashore in the nests, the number of average eggs by a sea turtle are 110 eggs. However after the hatching, the sea turtle babies have to go the sea by themselves, during which most of them are killed, or eaten by different animals.

The very few who make it to the sea are than further reduced by the various marine attacking animals and thus the population is balanced.

most community's take hundreds of years to become stable

not only is it colder, it also becomes darker, less salty, and more dense.
