Scenario People Utilize Plants to Meet Many Everyday Needs, Including Food

Multiple Choice

Scenario
People utilize plants to meet many everyday needs, including food, fiber, and building materials. However, not many of the over 300,000 known species of plants are used by people. One species with a lot of future promise is the jatropha tree. This species is native to Central America and is now found throughout the tropics. Many people believe the jatropha could help alleviate poverty in many areas of the world, as the seeds produce an oil that can be used for cooking, lighting, or generating electricity. This oil can also be mixed with diesel fuel or petrol to produce a biofuel. Mature trees produce between 5 and 15 kg of seeds per year and can live more than 30 years.
-What is a possible disadvantage of using jatropha seeds to produce oil?

A) Seeds from the jatropha tree would become infected with fungus from Central American rainforests.
B) Production of jatropha trees will increase parasitic relationships with native plants.
C) Biofuel produced from the jatrohpa tree oil will become contaminated with fungal spores.
D) Growing jatropha trees to produce oil may lower food production if a lot of land is needed for food production.
