Why do the two animals have different adaptations?
Thorny devils and superb lyrebirds both have different adaptations to meet their different needs as they both live in different habitats. This means they require different nutrients, face different temperature ranges, have different predators etc. For example, water supply for thorny devils is limited so they need to adapt to accommodate for this in order for them to survive, whereas lyrebirds don’t have this problem living in a forest so they do not need adaptations that help them to acquire water.
Which organism (plants or animals) would have a greater tolerance range for temperature changes?
Plants would be expected to have a greater tolerance range for temperature changes. This is because they have chemical concentration changes that occur in them that allow them to accommodate for any changes in temperature, unlike animals. Plants are able to close their open when temperatures get warm which allows the water to be evaporated, therefore decreasing the plants internal temperature. They are also able to wilt their leaves so that they are vertical, decreasing the surface area of the plant that is exposed to the sun. When temperatures are cold, many plants also drop their leaves to reduce water loss and reduce the risk of transpiration. Different plants have other responses to temperature changes to help them survive, but animals can usually only adapt to changes through their behaviours such as hibernating or huddling together.
