Pls answer, will give 50 points.

Answer 1

An animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.

Different animals have different senses heightened, that lets them use different mechanisms to navigate. Some of the mechanism include remembering landmarks, solar navigation, star navigation, magnetoreception, olfaction, gravity receptors etc.

For example, a bird using landmark to navigate will find it hard to navigate in the same way again if the landmark has been changed. So it has to depend on other senses such as olfaction or magnetoreception to navigate.

Therefore, an animal might use more than one type of clue to find its way due to change in the way one mechanism used to work.
