a) beneficial insects may be adversely affected.
b) plants have an increased resistance to insect pests.
c) there is an increased need for inorganic fertilizers.
d) genetically engineered plants may have a longer shelf life

A)Beneficial insects may be adversely affected.

While some insects are plant pests, many others a necessary to pollinate the flowers of plants that eventually give us fruits, vegetables, and seeds for human use. Bioengineered plants often require less water, fertilizers, pesticides, and the use of herbicides.
