Environmental Explorations

A scientist at a zoo was developing a forest environment to support a population of wolves. Which physical characteristics need to be in place to support the population of wolves?

• Cool temperatures and sandy beaches

• Grassy lands with no trees

• Moist air and many trees

• hot and dry temperatures with no rain

Which of the following is not a physical characteristic of the grasslands?

• Dry, hot and no rain

• Open fields and lots of grass

• Grazing animals; like cows and goats

• Sun and some rain

Which physical characteristic of the tundra would best support a population of polar bears?

• Icy soil and cold temperatures

• Rocky soil and no rainfall

• Tall trees and fresh water springs

• Flat, grassy fields

What would happen to this food chain if the grass was removed?

• If the grass was removed, there would be an increase in rabbits

• If the grass were removed, there would be a decrease in mice

• If the grass were removed, there would be an increase in foxes

• If the grass were removed, their would be a decrease in temperatue

Which of the following shows the flow of energy though a food chain?

• fish $\longrightarrow$  plant  $\longrightarrow$  shark

• shark  $\longrightarrow$  fish  $\longleftarrow$  plant

• plant  $\longrightarrow$  fish  $\longrightarrow$  shark

• shark  $\longrightarrow$  fish  $\longrightarrow$  plant

What would happen to the food chain if there were an increase in rats?

• The grass population would increase

• The snake population would increase

• The snake population would decrease

• The eagle population would decrease

What would happen to this food chain if the eagle could not find enough food to eat?

• The snakes would all die

• The snakes' population would increase

• The population of eagles would increase

• The population of rats would increase

How would a drought effect grassland organisms?

• All of the animals in the grasslands will die

• The population of plants would increase

• Some animals will move to a new location

• Some plants will move to a new location

What might cause a decrease in flowers in the grassland?

• Very rainy weather

• Very dry weather

• A decrease of rabbits

• An increase in bees

Why might an organism have long, strong legs

• To keep the organism cool

• The move and jump quickly

• To blend in to surroundings

• To be able to see pray
