Aquaponics and Hydroponics Relearning Assessment

Front

What is aquaponics?

Back

Aquaponics is a method of farming that combines raising fish and growing plants together in a symbiotic environment.

Front

What is hydroponics?

Back

Hydroponics is a method of growing plants without soil, using nutrient-rich water instead.

Front

What is the role of a water pump in an active hydroponics system?

Back

The water pump circulates nutrient-rich water to the plants, ensuring they receive the necessary nutrients.

Front

What is the role of gravity in a passive hydroponics system?

Back

In a passive hydroponics system, gravity helps to move water from the reservoir to the plants without the need for a pump.

Front

What are the components of an aquaponics system?

Back

Key components include a fish tank, grow bed, water pump, and filtration system.

Front

What is the nitrogen cycle?

Back

The nitrogen cycle is a natural process that converts nitrogen in the environment into forms usable by living organisms, including ammonification, nitrification, and assimilation.

Front

What is ammonification?

Back

Ammonification is the process of converting organic nitrogen from dead plants and animals into ammonia.

Front

What is nitrification?

Back

Nitrification is the process of converting ammonia into nitrites and then into nitrates, which plants can absorb.

Front

What is assimilation in the nitrogen cycle?

Back

Assimilation is the process by which plants absorb nitrates from the soil and use them to create proteins.

Front

What is a grow bed in aquaponics?

Back

A grow bed is a container filled with a growing medium where plants are cultivated in an aquaponics system.
