Marine - Chap 9 and 10 Review

Front

What are the essential conditions for algae-rich areas?

Back

Algae-rich areas need sunlight (shallow water), upwelling, and nutrients, as well as colder water which holds more nutrients.

Front

Why is it important for algae to float?

Back

Algae need to float because that's where the sunlight is, which is essential for photosynthesis.

Front

What role do phytoplankton play in fisheries?

Back

Phytoplankton are crucial to fisheries because fish need plankton for food.

Front

Which of the following is NOT a type of algae?

Back

Sharks are not a type of algae; the types of algae include brown algae (phaeophyta), green algae (chlorophyta), and red algae (rhodophyta).

Front

Why is upwelling significant for algae growth?

Back

Upwelling is important for algae growth because it brings nutrient-rich water to the surface where there is sunlight.

Front

Define phytoplankton.

Back

Phytoplankton are microscopic plants that live in aquatic environments and are a primary source of food for many marine organisms.

Front

What is the process of photosynthesis in algae?

Back

Photosynthesis in algae is the process by which they convert sunlight, carbon dioxide, and water into glucose and oxygen.

Front

Explain the term 'upwelling'.

Back

Upwelling is the process where deep, nutrient-rich water rises to the surface, supporting marine life and algae growth.

Front

What are the main types of algae?

Back

The main types of algae include brown algae (phaeophyta), green algae (chlorophyta), and red algae (rhodophyta).

Front

How does sunlight affect algae growth?

Back

Sunlight is crucial for algae growth as it is necessary for photosynthesis, allowing algae to produce energy.
