Final answer:
Some biofuels, like corn for ethanol, flourish more than others due to factors such as crop availability and suitability, competition with food production, and land/resource requirements.
Step-by-step explanation:
The flourishing of some biofuels, such as corn for ethanol, can be attributed to a few key factors.
1. Availability and suitability of crops: Some biofuels, such as corn and sugar cane, have high sugar content and can be easily fermented to produce bioethanol.
2. Competition with food production: Corn and sugar cane are crops that can be grown specifically for biofuel production without impacting food supplies. However, other biofuel crops may compete with food production, limiting their growth.
3. Land and resource requirements: Certain biofuel crops, like corn and soybeans, have well-established growing and harvesting methods. On the other hand, cellulosic conversion from plant waste remains undemonstrated on a larger scale.
