What is an EcoColumn?

Back

An EcoColumn is a self-sustaining ecosystem model that demonstrates the interactions between aquatic and terrestrial environments, often used for educational purposes.

Front

What role do nitrifying bacteria play in an EcoColumn?

Back

Nitrifying bacteria convert ammonia, produced from fish waste, into nitrites and then into nitrates, which are less harmful to fish.

Front

What is the process of decomposition in an EcoColumn?

Back

Decomposition involves the breakdown of organic matter, such as dead fish and plants, which releases nutrients back into the ecosystem.

Front

How does the presence of dead fish affect plant growth in an EcoColumn?

Back

Dead fish provide nutrients that can enhance plant growth when buried in the terrestrial chamber.

Front

What is the significance of pH levels in an EcoColumn?

Back

pH levels affect the health of aquatic life; certain pH levels are necessary for fish survival and plant growth.

Front

What happens to dissolved oxygen levels in an EcoColumn over time?

Back

Dissolved oxygen levels can fluctuate due to factors like plant photosynthesis and fish respiration.

Front

What is the impact of healthy aquatic plants on pH levels?

Back

Healthy aquatic plants can help stabilize pH levels by absorbing carbon dioxide during photosynthesis.

Front

What is ammonia, and why is it harmful to fish?

Back

Ammonia is a toxic byproduct of fish waste; high levels can lead to fish stress and death.

Front

What are nitrates, and how do they benefit plants?

Back

Nitrates are a form of nitrogen that plants can absorb and use for growth, making them essential for healthy plant development.

Front

What is cellular respiration, and how does it affect pH in an EcoColumn?

Back

Cellular respiration by fish produces carbon dioxide, which can lower pH levels in the aquatic chamber.
