Organisms are those that are active during the day. Common examples include most species of butterfly and dragonfly

• Ectothermic

• Diurnal

• Endothermic

• Nocturnal

Eagles and other birds of prey have sharp, hooked beaks that are good for ripping and tearing into the flesh of their prey, while sparrows and other seed eating birds have short, pointed beaks for cracking open seeds. This is an example of

• Structural Adaptation

• Behavioral Adaptation

• Mimicry

• Camouflage

Training to hunt or find food, build a nest, finding shelter is an example of

• Structural Adaptation

• Behavioral Adaptation

• Mimicry

• Camouflage

Viceroy butterflies look so much like monarch butterflies, they avoid being eaten by birds is an example of

• Diurnal

• Camouflage

• Mimicry

• Nocturnal

Circadian rhythm deals with

• structural adaptations

• behavioral instincts

• eating schedules

• sleep cycles

Any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. Examples include the fishes, amphibians, reptiles, and invertebrates.

• Endotherm

• Ectotherm

Many animals snuggle up in caves, burrows (holes in the ground), or hollow tree trunks and sleep during the cold winter months when food is harder to find and cold weather makes it harder for their bodies to work. This is an example of

• structural adaptation

• migration

• hibernation

• homeostasis

The way animals maintain a stable internal balance in their body. It allows animals to function in the changing external conditions surrounding their body.

• Homeostasis

• Osmoregulation

• Adaptation

• Mimicry
