Adaptations

Desert plants have structures that help them to collect and store water. These structures are helpful in...

• Tropical climates

• Windy climates

• Wet climates

• Dry climates

Different plants have different leaves. The leaves that a plant has are adapted to its environment.Why do evergreen plants have needles rather than leaves?

• The needles allow the plant to float on water.

• The needles are covered in wax to prevent freezing.

• The needles are designed to catch significant amounts of water.

• The needles are covered in wax to help the plant survive hot summers.

The koala is an animal native to Australia. Despite the popular name, koala bear, they aren't bears, but marsupials like kangaroos, that keep their newborns in a stomach pouch.

They have developed very differently than other marsupials, in part because they spend most of their lives in the eucalyptus trees that serve as their main source of food.

What adaptation helps them lead this tree bound life?

• The use of pouches to hold koala newborns.

• Grey fur that keeps them hidden from predators.

• Hands, feet, and claws that are perfect for gripping branches.

• Distinct calls they use to communicate potential danger to one another.

Otters have webbed feet that help them swim, and nostrils and ears that close when they dive underwater. These suggest that the otter is most suited for which environment?

• river habitat

• forest habitat

• desert habitat

• arctic habitat

What adaptation helps protect a cactus against herbivores?

• spines

• deep roots

• waxy stems

• succulent leaves

A beetle population has some brown and some yellow beetles. A new predator comes to the environment and begins eating the yellow beetles because they can be seen more easily. Then, because the yellow beetles don't live as long, their color is not inherited and fewer yellow beetles hatch. Over time there the yellow beetles are reproduced less and less.

What is this an example of?

• adaptations

• mutations

• natural selection

Why might some plants have thorns?

• to stay safe from animals that want to eat the plant
• to attract insects that spread pollen to other plants
• to take in nutrients from the air
• to provide shade for the plant
