Question

what are three water conservation practices? using water-retaining crops using permeable paving for rainwater harvesting alternating water sources for crop watering using drought-resistant crops implementing efficient irrigation systems

Explanation:

To identify three water conservation practices, we analyze each option:

• "Using drought - resistant crops": These crops need less water, reducing overall water use for agriculture.
• "Implementing efficient irrigation systems": Systems like drip irrigation deliver water more precisely, minimizing waste.
• "Using permeable paving for rainwater harvesting": Permeable paving allows rainwater to seep into the ground, which can be collected and reused, increasing water availability.

Other options: "Using water - retaining crops" is less common as a primary conservation practice, and "Alternating water sources for crop watering" doesn't directly conserve water but rather manages sources.

Answer:

1. Using drought - resistant crops
2. Implementing efficient irrigation systems
3. Using permeable paving for rainwater harvesting
