Explanation:

1. For the first question: Coal, oil, natural gas, methane, and uranium ore are non-renewable or have high environmental impacts. Sunlight and wind are renewable energy sources with minimal environmental harm.
2. For the second question: Bioaccumulation in fish often happens when toxic pesticides enter the food chain. Reducing pesticide use directly cuts this toxic input.
3. For the third question: Crop rotation is a conservation practice that maintains soil nutrient diversity and health, while herbicides, excess fertilizer, and pesticides are harmful to the environment or not conservation-focused.

Answer:

1. B. sunlight and wind
2. A. reduce pesticide use
3. D. Farmers use consistent crop rotation techniques to make sure soil contains a variety of nutrients.
