Unit 7B Science Review

Which of the following is the MOST LIKELY effect of cutting down trees in a forest habitat?

• Animals that cannot find what they need will move to a new location.

• All of the animals will begin to live in burrows underneath the ground.

• Many animals will learn to fly to reach higher branches.

• All of the animals in the forest will die in a short period of time.

Many animals have adaptations that help them survive the colder winter temperatures of Georgia. Would it be better it turtles migrated or hibernated? Explain your thinking.

• hibernate, so they do not have to travel far

• hibernate, so they can get the rest they need

• migrate, so they can still eat and survive outside

• migrate, to they can move to new places

A farmer bought some land that was full of deer. He fenced in the land and brought in some cattle. What might happen to the deer in the habitat?

• The number of deer will increase because food is plentiful.

• Nothing because the deer will share the grass with the cattle and live in the fenced area.

• The deer will migrate to another place because they don't like cattle.

• The deer will starve or move because there is not enough grass for both the cattle and the deer.

A student went down to the Atlantic Ocean coast and collected seaweed from the ocean water to put in her freshwater pond in the Piedmont region. The seaweed did not survive in the new pond.

What is the BEST explanation for why the seaweed did not survive in the new pond?

• The seaweed needs sandy soil at the bottom of the ocean.

• The seaweed didn't get enough sun.

• The seaweed can only survive in salt water.

• The seaweed needs a hot climate.

The leaves on the trees in the Blue Ridge Mountains often change color and fall before the leaves on the trees in other regions of Georgia. Why does this MOST LIKELY happen?

• The leaves in the mountains are more likely to freeze earlier.

• There are less animals to eat the leaves than in other regions.

• The trees in the mountains are not as strong as those in other regions.

• All of the trees in the other regions do not have leaves because they are evergreens.

Lily plants grow best in the shade of large trees. What change could have a harmful effect on the lily plant?

• The trees grew more leaves.

• The clouds blocked the sun for a few days.

• The trees were all cut down.

• There was more rainfall.

Crabs have special adaptations and features that help them survive best in the ocean habitat. Which of the following will happen to the crab if it were placed in a mountain habitat?

• The crab would survive because they do not have specific needs in order to survive.

• The crab would not survive because they live in and around saltwater and cannot live without the food they need.

• The crab would not survive because they need humidity and warm temperatures to survive.

• The crab would survive because there is water in the mountain region.

A pitcher plant lives in very wet and muddy areas, needs a warm moist climate, and needs lots of insects in all of the seasons.

If a class planted a pitcher plant in their garden in the Piedmont region in August and it began to die in October, which of the following is the BEST explanation for this?

• The pitcher plant did not get enough sunlight in the Piedmont.

• The climate in the Piedmont was not dry and cold enough.

• The pitcher plant was too hot in the Piedmont.

• The climate in the Piedmont was not wet and warm enough.
