Some trees were cut down to create space for the road. The remaining woods line both sides of the highway. Which of the following will most likely happen to the ecosystem as people begin DRIVING on the highway?

• The highway will soon be overgrown by trees as new seedlings sprout in the road.

• New animal populations will move to the area increasing the ecosystem diversity.

• Animal populations will decrease in size because some individuals are struck by cars.

• Animals that live in trees will decrease because they will have to move to a different forest.

Human activities constantly affect the ecosystems that are in close proximity with human settlements. The graph shows the population of oak trees around the city of Greenville, South Carolina. If all other factors remain the same, what will most likely happen to the oak tree population over the next five years if the human population continues to grow?

• If all other factors remain the same, what will most likely happen to the oak tree population over the next five years if the human population continues to grow?

• The oak population will increase as people become more aware of environmental issues.

• The oak population will stay the same as people plant new trees to replace trees that are cut.

• The oak population will decrease as people build more homes.
