Question

Recently, some crop plants were genetically modified to be immune to the effects of weed killers. Which of the environmental concerns should be considered before planting the resistant crops?

A increase in crop diversity.
A decrease in crop diversity.
A increase in crop yield.
A decrease in crop yield.

Answer 1

B. A decrease in crop diversity

Step-by-step explanation:

I took the test and this is the answer

Answer 2

A decrease in crop diversity.

Step-by-step explanation:

Developing genetically modified crops with the purpose of having stronger immunity against weed killer is of major environmental concern. This resistance will help the GM plants survive and use most of the nutrients and resources. Nevertheless, other crop plants, which are growing in the same area, would not be able to survive and this could lead to an overall decrease in crop diversity. Such a decrease in diversity is definitely not good for the biogeochemical cycles.
