Sunlight Zone Flashcard

Front

What is the sunlight zone in the ocean?

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 a depth of about 200 meters.

Front

What is a primary producer in the sunlight zone?

Back

A primary producer is an organism that can produce its own food through photosynthesis. In the sunlight zone, phytoplankton are the primary producers.

Front

How does pollution affect the sunlight zone?

Back

Pollution can lead to harmful algal blooms, which deplete oxygen and harm marine life, reducing biodiversity in the sunlight zone.

Front

What role do phytoplankton play in the ocean ecosystem?

Back

Phytoplankton are crucial as they form the base of the marine food web, providing food for a variety of marine organisms.

Front

What is the average depth of the sunlight zone?

Back

The average depth of the sunlight zone is approximately 200 meters.

Front

Name one characteristic of the sunlight zone that supports marine life.

Back

The abundance of sunlight is a key characteristic that supports photosynthesis and the survival of marine life.

Front

What are the main threats to biodiversity in the sunlight zone?

Back

The main threats include pollution, overfishing, and habitat destruction.

Front

What is the significance of the sunlight zone for marine animals?

Back

The sunlight zone is significant as it provides a habitat rich in food sources and supports a diverse range of marine life.

Front

How does overfishing impact the sunlight zone?

Back

Overfishing can lead to the depletion of key species, disrupting the balance of the marine ecosystem and affecting biodiversity.

Front

What is the relationship between sunlight and photosynthesis in the ocean?

Back

Sunlight is essential for photosynthesis, allowing primary producers like phytoplankton to convert light energy into chemical energy, forming the basis of the ocean food web.
