How do trees in agroforestry systems help reduce CO2 emissions from raising chickens?

• By increasing egg production

• By reducing the need for external feed

What is one of the benefits of agroforestry in terms of biodiversity?

• It reduces the number of insects

• It increases the variety of plant species

• It decreases the need for pesticides

• It boosts the population of beneficial insects

What is a challenge of implementing agroforestry systems in certain areas?

• High temperatures

• Excessive rainfall

• Unsuitable soil conditions

• Lack of sunlight

What is a potential benefit of agroforestry in the context of climate change?
