Carbon Capture: Phytoplankton

The video discusses the crucial role of phytoplankton in the carbon cycle, highlighting their ability to absorb carbon dioxide and release oxygen. It addresses the challenges posed by pollution and global warming, which reduce phytoplankton populations. The video explores methods to boost phytoplankton growth, such as using urea, but warns of potential ecological disruptions. It concludes by emphasizing the complexity of managing nature and the long-term implications of human intervention.

What role do phytoplankton play in the carbon cycle?

• They release carbon dioxide and absorb oxygen.

• They absorb carbon dioxide and release oxygen.

• They absorb oxygen and release carbon dioxide.

• They do not participate in the carbon cycle.

What is one of the main challenges phytoplankton face due to climate change?

• Increased predator populations.

• Warming of ocean surface waters.

• Decreased sunlight reaching the ocean surface.

• Increased salinity in the ocean.

How can phytoplankton growth be artificially stimulated?

• By increasing the ocean's temperature.

• By reducing the amount of sunlight.

• By adding salt to the ocean.

• By releasing a nitrogen-rich compound called urea.

What is a potential downside of excessive phytoplankton growth?

• Decreased levels of dissolved oxygen in the water.

• Increased biodiversity in marine ecosystems.

• Increased levels of dissolved oxygen in the water.

• Decreased water temperature.

What does the need to manage phytoplankton growth illustrate about combating climate change?

• It is complex and requires ongoing management.

• It is unnecessary as nature will restore itself.

• It is simple and requires minimal intervention.

• It can be achieved by reducing human activity.
