Efficient Food Production: Farming and Fishing Techniques

What is one method to increase the efficiency of energy transfer in food chains?

• Increasing animal movement

• Keeping animals in cooler environments

• Limiting animal movement

• Feeding animals less

What is a potential downside of battery farming?

• Increased animal movement

• Higher energy loss

• Rapid spread of diseases

• Decreased meat production

Why is sustainable fishing important?

• To increase fish population

• To prevent the extinction of fish species

• To reduce the size of fish caught

• To increase the number of fish caught

How does increasing mesh size in fishing nets contribute to sustainability?

• It reduces the number of fish caught

• It increases the catch of young fish

• It allows small fish to escape and grow

• It catches more fish

What is a benefit of fish farming?

• It reduces the need for high protein diets

• It protects wild fish stocks

• It increases the size of fish caught

• It decreases fish growth rates

Why might shorter food chains be more efficient?

• They involve more energy transfer steps

• They increase the need for animal feed

• They reduce the amount of biomass lost

• They require more land

What is a reason for using land to graze animals instead of growing crops?

• Crops can be grown everywhere

• Some lands are unsuitable for crops

• Grazing animals require less space

• Crops provide more protein than meat
