1. The octopus in the video is able to change its shape, behaviour, size and colour. Explain why this is important for the survival of this species.

The most obvious reason such a soft-bodied animal would change color is to hide from predators and octopuses are very good at this. They can change not only their coloring, but also the texture of their skin to match rocks, corals and other items nearby.

answer: c.

explanation:

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
