Test Review: Ecocolumns

Front

What is the relationship between water temperature and dissolved oxygen?

Back

Cold water holds more dissolved oxygen than warm water.

Front

What role does an aquatic plant play in the bottom chamber of an ecocolumn?

Back

Helps put oxygen in the water through photosynthesis, helps the nitrogen cycle from the bacteria colony that live on it, and feeds your fish.

Front

What does the bottom chamber of an ecocolumn represent in nature?

Back

Pond/Lake.

Front

What happens to sensitive organisms when dissolved oxygen (DO) levels drop below 4 mg/L?

Back

Sensitive organisms can become stressed.

Front

What is the role of detritivores in an ecosystem?

Back

They help add nutrients to the soil in their feces and aerate the soil.

Front

Define photosynthesis.

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the nitrogen cycle?

Back

The process through which nitrogen is converted between its various chemical forms, essential for plant growth.

Front

What is dissolved oxygen (DO)?

Back

The amount of oxygen that is present in water, crucial for aquatic life.

Front

Why is aeration important in soil?

Back

Aeration allows air to reach plant roots and helps with water drainage.

Front

What are detritivores?

Back

Organisms that feed on dead organic matter, helping to decompose it.
