behavioral separation

Explanation:

The separation leading to the speciation of the two groups of killer whales would be considered a behavioral separation.

<em>Behavioral separation or isolation is a form of separation that occurs between two groups of individuals (that use to be of the same group) as a result of preference for a particular behavior or set of behaviors.</em>

The preference for the behavior eventually leads to the two groups becoming separate species, a form of speciation known as sympatric speciation.

netineya [11]

Answer:

Frogs and toads are carnivores, which means that they will eat meat. Small to medium sized frogs eat insects such as flies, mosquitoes, moths and dragonflies. Larger frogs will eat larger insects like grasshoppers and worms. Some large frogs will even eat small snakes, mice, baby turtles, and even other smaller frogs , which means that if one of the A ponds have fish , mosquito or any of the above then frogs are more likely to be found in that A pond ,

-  The majority of species are found in moist tropical climates. Frogs fall into one of three categories depending on the habitat they are typically found in: terrestrial, arboreal or aquatic. Many frog species live in temperate climates that have winters, and hibernation during the cold months is key to their survival., so if pond A is hot and has humid climate then frog is likely to be fond in B pond

frogs = These could tolerate water of pH 3.35
