Question

what should you add to your ecocolumn if you want to test the effects of nutrients on your ecocolumn? styrofoam carbon monoxide inorganic fertilizer oxygen

Explanation:

Step1: Analyze each option

• Styrofoam: It is a non - nutrient, non - biodegradable material. It has no role in providing nutrients and can be harmful to the ecosystem in an ecocolumn.
• Carbon monoxide: It is a toxic gas. It is not a nutrient and can cause harm to the organisms in the ecocolumn.
• Inorganic fertilizer: It contains essential nutrients like nitrogen, phosphorus, and potassium. Adding it can be used to test the effects of nutrients on the ecocolumn ecosystem (e.g., plant growth, microbial activity etc.).
• Oxygen: While oxygen is essential for respiration, it is not a nutrient in the sense of what is being tested here (nutrients for growth and development of organisms in terms of chemical compounds like N, P, K).

Answer:

C. inorganic fertilizer
