What role does carbon dioxide play in cellular respiration and photosynthesis?

• It is a product of photosynthesis and a reactant in respiration.

• It is a reactant in photosynthesis and a product in respiration.

• It is not involved in either process.

• It is only involved in photosynthesis.

A forest ecosystem experiences significant deforestation. Predict how this will affect the biodiversity and carbon storage in the area, and explain your reasoning.

• Biodiversity and carbon storage will increase because more sunlight reaches the ground.

• Biodiversity and carbon storage will decrease due to loss of habitat and fewer trees to store carbon.

• Biodiversity will increase, but carbon storage will decrease.

• There will be no effect on biodiversity or carbon storage.

Given a scenario where a new predator is introduced into a food web, explain how this could cause a cascade effect throughout the ecosystem.

• The new predator will only affect its prey and not other species.

• The new predator could reduce prey populations, which may increase the abundance of the prey’s food and decrease populations of other predators, affecting the entire food web.

• The new predator will have no effect on the ecosystem.

• The new predator will increase the number of producers.

A population of deer in a forest exceeds the carrying capacity due to a lack of predators. What are two likely consequences for the deer and the forest ecosystem?

• Deer population will stabilize and forest health will improve.

• Deer population will decrease due to starvation, and the forest will experience overgrazing.

• Deer population will increase indefinitely, and the forest will remain unchanged.

• Deer will migrate and the forest will become more diverse.
