Sunlight Zone Flashcard

Front

What is the sunlight zone?

Back

The sunlight zone, also known as the euphotic zone, is the upper layer of the ocean where sunlight penetrates, allowing photosynthesis to occur. It typically extends to about 200 meters deep.

Front

How does pollution affect the sunlight zone?

Back

Pollution can block sunlight from reaching the surface of the water, which can disrupt the photosynthesis process and harm marine life.

Front

What is the primary source of energy in the sunlight zone?

Back

The primary source of energy in the sunlight zone is the Sun's light and heat.

Front

What is phytoplankton?

Back

Phytoplankton are microscopic plants that live in the sunlight zone and are the primary producers of food for many marine animals.

Front

What role do secondary consumers play in the sunlight zone?

Back

Secondary consumers, such as tuna, are organisms that eat primary consumers (like zooplankton) and help maintain the balance of the marine food web.

Front

What is a primary producer?

Back

Primary producers are organisms that produce their own food through photosynthesis, such as phytoplankton and seaweed.

Front

What is the significance of the abundance of sunlight in the sunlight zone?

Back

The abundance of sunlight in the sunlight zone supports photosynthesis, which is essential for the growth of primary producers and the overall health of marine ecosystems.

Front

What are the main types of organisms found in the sunlight zone?

Back

The sunlight zone is home to a variety of organisms, including phytoplankton, zooplankton, fish, and marine mammals.

Front

What is the relationship between phytoplankton and marine food webs?

Back

Phytoplankton serve as the base of the marine food web, providing energy and nutrients for primary consumers and higher trophic levels.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, defined by how an organism obtains its energy, such as producers, primary consumers, and secondary consumers.
