Biotechnology has helped produce crops that are resistant to certain pests, crops that produce high yields, and more nitrogen-ef
ficient crops. What is a negative impact that bioengineered plants may have on the environment? 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
Explanation: 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.
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
