The water would freeze across the surface of the lake, blocking the dissolving of oxygen and nutrients. <span>Water is actually less dense when frozen, which is why ice cubes and ice bergs all float. This is also why you can ice skate on a lake if the ice gets thick enough on the surface. Many organisms that live in freezing lakes have special adaptations which help them survive.</span>
The correct answer to this question is a: metamorphosis. Many
insects take on multiple forms through different parts of their lifecycle. For
example, many lepidopteran species (i.e., butterflies) include a caterpillar
juvenile stage. To reach the adult stage, the juvenile stage has to go through
metamorphosis, where its adult form is strikingly different from its juvenile
form.
