What special adaptation does a skunk have to protect itself from predators in the forest?

Striped skunk

Plants cannot move from place to place when the conditions in their environment change.

Instead, plants can make changes to the way they grow by turning and bending in response to a stimulus.

This is known as .

  • AThick fur helps the arctic fox survive the cold.
  • BThe arctic fox uses camouflage to survive the cold.
  • CThe arctic fox hibernates in the winter to survive the cold.


There are many dangerous predators in the Amazon rain forest. The skin of the poison dart frog is toxic (poisonous) when eaten.

How else has this frog adapted to survive predators?

The poison dart frog-72 ppi
  • AIts brightly colored skin warns animals away.
  • BIts feet are not webbed, making it a poor swimmer.

  • BHeat
  • CLight


Plants and animals can adapt their structure or behavior to help them survive. The Venus flytrap has adapted to survive in soil that does not provide enough nutrients.

It can trap insects by closing its leaves around them. This helps the plant get the nutrients it needs. Which type of adaptation is this?

Venus flytrap structural
  • ABehavioral
  • BStructural


Plants and animals make adaptations to survive in forest environments. Tropical rain forests receive lots of rain, which can be harmful to some plants.

Banana leaf - 72 ppi

This leaf of the banana plant has lots of grooves. How does this prevent the leaves from getting too much water?

  • AThe grooves help the leaf fall off the plant when it rains.
  • BThe grooves allow the rain drops to drain away easily.
  • CThe grooves allow the leaf to absorb lots of rain.


Fill in the blank: The cattail plant has adapted to the wetland environment by growing a very long .

Cattails - 72 ppi
  • Aroot
  • Bflower
  • Cstem


Why do plants need to adapt to their environment?

Wilted pot plant-72 ppi
  • ATo make sure that animals have enough food to eat
  • BTo get the light and water they need to survive
  • CSo bees can pollinate their flowers
