A fungus was infecting a farmer's crops, killing many of the plants. The farmer decided to use a chemical to kill the fungus. However, he discovered that in another country, farmers control this fungus by releasing insects to kill it. In that country, the population of the released insects is kept under control naturally by a local bird that preys on the insects. The farmer decided to order some of the insects to release in his fields. How might the release of these insects be harmful to the local ecosystem?
A) The insect may increase crop yields by contributing to the spread of the fungus.
B) The insect may alter the food web by providing an additional food source to birds.
C) The insect may become an invasive species if it has no natural predators.
