Answer:
These organisms should be adapted to live in this enviroment, i.e., they need to have adaptations to breathe, to swim (fins), streamlined bodies to move through the water, to eat the food found in the region, etc. Moreover, in this environment, the diversity tends to be high because marine regions are often characterized by their richness.
Answer:
A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
