The video discusses the concept of acidification, focusing on pH levels and their environmental impact. It highlights the challenges of conducting large-scale experiments, particularly in mesocosm settings, where plants absorb CO2 during the day. The discussion includes the need for massive CO3 additions to simulate real-world conditions.

What is a common misunderstanding about acidification?

• It involves high pH levels.

• It is unrelated to pH levels.

• It only affects animals.

• It is beneficial for all plants.

What is a mesocosm used for in experiments?

• To simulate small-scale environments.

• To replicate large-scale natural systems.

• To measure pH levels directly.

• To grow plants in isolation.

Why is it challenging to conduct large-scale acidification experiments?

• They are not affected by environmental factors.

• They need massive amounts of materials.

• They are identical to small-scale experiments.

• They require minimal resources.

How do plants in mesocosms behave during the day?

• They require less CO3.

• They remain inactive.

• They absorb CO2.

• They release CO2.

What is added to mesocosms to maintain balance?

• Minimal amounts of CO3.

• Large amounts of CO3.

• Minimal amounts of CO2.

• Large amounts of CO2.
