What is camouflage?
An adaptation that helps an animal blend into its surroundings.
Why do animals need adaptations?
To help them survive in their environment.

What is the main purpose of camouflage?
To help an animal avoid being seen by predators or prey.
An animal has sharp claws and teeth. What are these adaptations likely useful for?

A rabbit lives in an area where hawks are common. Name one adaptation would help the rabbit survive.

What are the 3 parts that make up the nervous system?
Brain, spinal cord, and nerves
A duck has webbed feet. How do webbed feet help a duck survive?

True
Explain the difference between camouflage and simply hiding behind something.
Camouflage allows an animal to blend into its surroundings, making it difficult to see even when it is in plain sight.
Two animals live in the same cold environment. Animal A has thin fur while Animal B has thick fur and a layer of fat. Which animal is better adapted to the environment? Why?
Animal B because its thick fur and layer of fat help keep it warm in the cold environment.
An animal has very sensitive skin that allows it to detect vibrations or movement around its body. Which sense would this adaptation improve?
Touch
A desert animal is active mostly at night instead of during the hottest part of the day. How could this behavior help the animal survive?
It helps the animal avoid extreme heat and conserve (save) water/energy.
A rabbit has excellent hearing and powerful back legs. A fox enters its habitat. Explain how BOTH adaptations could help the rabbit survive.
Its hearing can help it detect the predator, and its powerful legs can help it escape.
Why do some predators need camouflage even though nothing is hunting them?
It helps them sneak up on prey.
Why might an animal that has excellent adaptations still struggle to survive if its habitat is destroyed?
Adaptations help animals survive in specific environments. If their habitat is destroyed, they may lose access to food, water, shelter, or a place to hide from predators. This makes survival more difficult.
