A student observing birds in a park records some ways that birds interact with living and nonliving parts of their environment. All the following  observations are was that a bird interacts with nonliving parts of its environment except______

• reacting to morning sunlight by singing
• drinking and taking a bath in a puddle of water
• responding to cold temperatures by fluffing its feathers
• feeding insects to its chicks

What would most likely happen to the carbon dioxide–oxygen cycle if Earth’s large forests were all cut down?

•  There would be more carbon dioxide in the atmosphere because fewer plants would be using it to produce their own food.
• The remaining plants would stop producing carbon dioxide, and animals would use less oxygen.
• The remaining plants would produce more oxygen, and animals would produce less carbon dioxide.
• There would be more oxygen in the atmosphere because fewer plants would be using it to produce their own food.

• By competing with other animals for food
• By moving slower than most other animals
• By causing other animals to reproduce more
• By eating foods that no other animals eat

Prairie dogs eat plants and dig underground tunnels. Prairie dog tunnels help breakup hard prairie soils, and the animals’ waste adds nutrients to the soil. In the past,large groups of prairie dogs lived in many parts of the U.S. Great Plains, but people have destroyed most of these colonies.  Which of these will most likely happen when prairie dogs are removed from an area?

• The population of predators that eat prairie dogs will decrease.
• The population of plants that prairie dogs eat will decrease.
• The nutrients in the soil will increase.
• The number of underground tunnels will increase.
