CLEAN: Ocean acidification threatens marine life

The video discusses enclosing a large body of water with organisms and acidifying it based on future projections. It explores how ecosystems respond to these changes, focusing on the Arctic food system, where small organisms feed larger animals like whales and birds.

What is the primary goal of enclosing a large body of water with organisms?

• To increase the water temperature

• To observe the ecosystem's response to acidification

• To enhance the growth of phytoplankton

• To reduce the number of organisms

How will the acidification process be guided?

• By historical data

• By random selection

• By current weather conditions

• By future projections

What is the expected outcome of observing the ecosystem over 20, 40, and 60 years?

• To measure the increase in water temperature

• To find new species of fish

• To understand the long-term effects of acidification

• To determine the best fishing practices

What is the significance of key species in the Arctic food system?

• They are the largest animals in the ecosystem

• They feed on small particles and support larger animals

• They are the primary predators

• They are the only species affected by acidification

Which animals benefit from the key species in the Arctic food system?

• Whales, fish, and birds

• Reptiles and mammals

• Insects and amphibians

• Only fish
