In the galapagos islands, marine iguanas swim in salt water and vent excess salt from their nostrils. iguanas who are more efficient at venting the salt also have more offspring. what is the term that describes this effect, when organisms with an advantage are more likely to successfully have offspring? a. differential reproduction b. heritability c. variation d. overproduction

The correct answer would be A. Differential reproduction.

Differential reproduction refers to the different rate of reproduction of organisms according to their ability to adapt to the environment.

According to this phenomenon, the organisms which are better adapted to the environment tend to reproduce more as compared to the organisms which are less adaptive.

Similarly, the organisms which are efficient at venting the salt reproduce more efficiently.
