Suppose a friend says that we don't need to worry about the rising temperatures associated with global climate change. Her claim is that increased temperatures will make planktonic algae grow faster and that carbon dioxide (CO₂) will be removed from the atmosphere faster. According to her, this carbon will be buried at the bottom of the ocean in calcium carbonate shells. As a result, the amount of carbon dioxide in the atmosphere will decrease and global warming will decline. A) Primary producers usually grow faster when CO₂ concentration increases, but to date they have not grown fast enough to make CO₂ levels drop. B) Primary producers usually grow slower when CO₂ concentration increases, so to date they can't make CO₂ levels drop. C) Primary producers grow fast enough to make CO₂ levels drop even today. D) Primary producers don't remove CO₂ from the atmosphere.

Sea levels are rising due to climate change while increasing numbers of people are moving into coastal areas. to accommodate more people, there has been increased construction of beachfront resorts and condominiums. how is this impacting sea turtle numbers and biodiversity and why? a. the increased human population in coastal areas has meant that more food is available to the turtles (e.g., dropped food, waste from restaurants), which has led to an increase in the numbers and diversity of sea turtles. b. there has been very little change in the numbers and biodiversity of sea turtles because the planet is so vast that they can simply relocate to less crowded beaches. c. this has resulted in a decrease in numbers and diversity of sea turtles because it is restricting available nesting sites, and hence reproduction. d. this has resulted in an increase in numbers and diversity of sea turtles because people are around to protect them from natural predators.
