D: The cell is the basic unit of structure and organization in organisms. Explanation: cause I got the question right.

This is known as a trophic cascade. The results of these trophic cascades can lead to an ecosystem being completely transformed. The impacts trickle down through each level, upsetting the ecological balance by altering numbers of different animal species, until the effects are finally felt by the vegetation.
It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.

Hope this helped :)
Have a great day
The statement 'fish are able to swim faster in a group to avoid being caught by the predator' BEST describes the most likely reason that swimming in a group can help fish avoid a larger predator.
<h3>What is an adaptation?</h3>
An adaptation is an evolutionary strategy to increase the chances of surviving and reproducing in a given environment.
In this case, swimming in a group can minimize friction in the aquatic environment and thus swim faster.
Evolutionary strategies and adaptations may also be individual, but they always have the same objective.
