What is the definition of a producer in an ecosystem?

Back

A producer, or autotroph, is an organism that can make its own food using sunlight or chemical energy, forming the base of the food chain.

Front

What is chemosynthesis?

Back

Chemosynthesis is a process by which certain bacteria near hydrothermal vents produce sugar by using chemical energy from the vent, rather than sunlight.

Front

What occurs during upwelling in ocean waters?

Back

Upwelling is the process where cold, nutrient-rich water rises to the surface, bringing nutrients that support marine life.

Front

How does upwelling affect ocean temperature?

Back

Upwelling causes the temperature of water in the area to decrease as cold water rises to the surface.

Front

What is the role of nutrients in ocean ecosystems?

Back

Nutrients are essential for the growth of phytoplankton, which are the primary producers in ocean ecosystems.

Front

How do energy and nutrients flow through ecosystems?

Back

Energy flows in one direction (from producers to consumers) while nutrients recycle within the ecosystem.

Front

What is the significance of phytoplankton in the ocean?

Back

Phytoplankton are microscopic plants that perform photosynthesis, producing oxygen and serving as the base of the marine food web.

Front

What is the difference between a consumer and a producer?

Back

Consumers are organisms that cannot produce their own food and rely on consuming other organisms, while producers create their own food.

Front

What are hydrothermal vents?

Back

Hydrothermal vents are openings in the ocean floor that release heated water and minerals, supporting unique ecosystems.

Front

What is the impact of ocean currents on marine life?

Back

Ocean currents help distribute nutrients and regulate temperatures, influencing the distribution and migration of marine species.
