Frogs have the trait of being the tetrapod.
Explanation:
when the female frogs lays her eggs directly in the water and fertilized eggs are hatched into aquatic tadpoles, on maturity they acquire legs and lungs. tadpoles have tails which is lost during the metamorphosis and the frogs also acquire the carnivorous tastes.
As evident that the male clasps the female from her back and releases the sperm through which the fertilized eggs are laid into water by the female frogs, mature frogs develops the trait of tetrapod. A Tetrapod animal is the one having four pods or four legs. A complete metamorphosis occurs in the life cycle of the frog.

Explanation:
Answer:
If an organism has a beneficial trait, they have a higher chance of survival, and if they can survive they can reproduce too.
Example: Speckled moths camouflage with the bark of trees and are not easily seen by predators. Black moths do not camouflage with the bark of trees and are easily seen by predators, therefore the black moths are eaten. Because the black moths have been eaten they cannot reproduce and pass on the trait for black wings to their offspring, but the speckled moths are able to reproduce because they survived and are able to pass on the speckled wing trait to their offspring.

Carrying Capacity. For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. Reproductive lag time may cause the population to overshoot the carrying capacity temporarily.
