Phytoplankton and Their Impact on the Environment

What role do phytoplankton play in the environment?

• They are a primary source of food for land animals.

• They control the weather patterns.

• They help in controlling food, air, and climate.

• They are responsible for ocean tides.

How are plankton generally classified?

• By their size and color.

• By their ability to swim.

• By their habitat location.

• By their lifestyle and function.

What is the primary process carried out by phytoplankton?

• Respiration

• Photosynthesis

• Decomposition

• Fermentation

What is unique about coccolithophores among phytoplankton?

• They can survive in freshwater.

• They are the largest type of phytoplankton.

• They create calcium carbonate shells.

• They produce bioluminescence.

How do coccolithophores contribute to carbon export?

• By taking carbon to the ocean floor.

• By absorbing carbon dioxide from the air.

• By releasing carbon into the atmosphere.

• By converting carbon into methane.

What is Alexandrium known for?

• Being the largest phytoplankton.

• Producing a powerful toxin.

• Supporting coral reef growth.

• Creating oxygen for marine life.

What impact does Alexandrium have on shellfish?

• It changes their color.

• It poisons them with toxins.

• It makes them more nutritious.

• It enhances their growth.

What is the purpose of the PACE instrument?

• To track ocean currents.

• To measure ocean temperature.

• To detect and differentiate phytoplankton species.

• To study marine animal behavior.

How does PACE differentiate between phytoplankton species?

• By their size.

• By their speed.

• By their sound.

• By their optical patterns.

What is the significance of PACE's hyperspectral view?

• It allows for faster data processing.

• It enhances the color of ocean images.

• It provides high sensitivity to detect phytoplankton.

• It reduces the cost of ocean exploration.
