What is upwelling?

Back

Upwelling is the process where nutrient-rich water from the deep ocean rises to the surface, often supporting high levels of biological productivity.

Front

Why is upwelling important to algae growth?

Back

It brings nutrient-rich water to the surface where there is sunlight.

Front

What are phytoplankton?

Back

Phytoplankton are microscopic plants that live in the ocean and are a crucial part of the marine food web.

Back

Algae-rich areas need sunlight (shallow water), upwelling, and nutrients.

Front

Why is it important that algae can float?

Back

That's where the sunlight is.

Front

What role do nutrients play in marine ecosystems?

Back

Nutrients are essential for the growth of algae and phytoplankton, which form the base of the marine food web.

Front

How does sunlight affect algae growth?

Back

Sunlight is necessary for photosynthesis, which allows algae to produce energy and grow.
