Explanation:

• Question 7: Hazardous waste is defined by its properties such as being harmful, toxic, flammable, reactive, or corrosive, not by color, weight, or smell.
• Question 8: Abiotic factors are non - living components of an ecosystem. Sunlight is non - living, while deer (animal), bacteria (microorganism), and trees (plant) are biotic (living) factors.
