Plant & Animal Adaptations

Some animals, such as lions, have pointed teeth, while other animals, such as cattle, have flat teeth. The difference in the shape of these animals' teeth is most closely related to---

• the type of organisms the animals consume

• the sounds the animals make

• the habitat the animals live in

• the type of predators the animals have

Newly hatched chicks of many types of birds, such as parrots, are covered in soft, fluffy down feathers. These feathers contain many small spaces where air gets trapped. In some animal species, such a Arctic foxes, the fur covering the animal's body consists of hollow strands of hair filled with air. The primary role of the air trapped in the down feathers and fur is most likely to--

• act as a cushion to prevent injuries from falls

• decrease the amount of energy needed for running or flying

• provide a layer of insulation to help control body temperature

• supply oxygen to be absorbed through the skin for transport to the lungs

A chameleon lies next to a large blue flower so predators can NOT find it. This is an example of

• camouflage

• mimicry

• migration

• instrinct
