Biocontrol, short for biological control, is a means to control pest populations (e.g., insects, plants) by intentionally introducing natural enemies of those pests. Biocontrol methods have benefits of typically being less expensive and less environmentally damaging than chemical pesticides. Which of the following should NOT be considered an example of biocontrol?
A) the spores of the Chinese caterpillar fungus that are sprayed on crop pests to parasitize and kill them
B) the application of herbicides that kill weeds harboring pest populations
C) the introduction of mites that prey upon citrus rust mites that infest and destroy citrus crops
D) the introduction of insect herbivores that eat weeds but do not feed on native plant species
17) Suppose that, while on a forest hike, you notice a blue fungus and a pink plant growing along the hiking trail. As you continue walking, you observe that if a blue fungus and a pink plant are growing side by side, they are both much larger than if the fungus and the plant are farther apart. What can you hypothesize about the relationship between the fungus and the plant?
A) The fungus and the plant have a symbiotic relationship that allows them to have more significant growth when they are near each other than when farther apart.
B) The fungus and the plant have a parasitic relationship that allows them to have more significant growth when they are near each other than when farther apart.
C) The roots of the plant are choking off nutrient flow to the fungal hyphae.
D) The plant is helping the fungus decompose leaf litter on the forest floor.
18) Corn smut is a fungus that grows in the ears of corn and changes corn kernels into black, powdery balls of fungus tissue. What would you hypothesize is the significance of the relationship between corn smut and corn?
A) Corn smut has a parasitic relationship with corn so that it can use the corn as a way to spread spores.
B) Corn smut has a symbiotic relationship with corn so that it can use the corn as a way to spread spores.
C) Corn smut helps to decompose corn more quickly and therefore replenishes nutrients in the soil at a faster rate.
D) Corn smut slows decomposition of corn and therefore reduces the rate at which nutrients are returned to the soil.
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. However, critics argue that planting the jatropha tree will take land needed for food production, which will in turn harm the poor
19) What would NOT be an advantage of using oil from jatropha seeds?
A) The oil is considered a renewable resource.
B) The oil can be used for generating electricity.
C) The oil can be used as a biofuel.
D) Growing jatropha tress to produce oil may lower food production.

20) Which of the following statements concerning the jatropha tree is TRUE?
A) Jatropha trees are found all over the world.
B) Everyone believes planting jatropha trees will be beneficial.
C) Humans use over half of the known species of plants for everyday uses.
D) Currently, the most valuable part of the jatropha tree is the seed.
