Question

what is an effect of growing crops with increased seed production?
reduced need for water
increased fertiliser and water use
lower input of fossil fuels

Explanation:

To determine the effect of growing crops with increased seed production, we analyze each option:

• "Reduced need for water": Crops, even with increased seed production, generally still need water for growth; increased seed production doesn't inherently reduce water needs.
• "Increased fertiliser and water use": To support higher seed production, crops often require more resources like fertilizers (to boost growth/yield) and water (for photosynthesis, nutrient uptake, etc.). This is a common outcome as higher productivity demands more inputs.
• "Lower input of fossil fuels": Increased seed production doesn't directly lead to less fossil fuel use. In fact, more intensive farming (for higher production) might use more machinery (running on fossil fuels) or processes that rely on fossil - fuel - derived inputs.

Answer:

B. Increased fertiliser and water use
