ANSWER !

1. (D) Pesticides kill insects that pollinate bean plants. 2. (B) Excess Herbicides

EXPLANATION !

1. When a field is sprayed with a pesticide, not all of the insects will die, and the ones that remain will produce offspring that will also be tolerant to the spray. This forces farmers to use more and different kinds of pesticides, so they can kill all of the insects that might destroy their crop.2. During periods of heavy rainfall, increased runoff brings more nutrients into a lake. These additional nutrients may be released from flooded soils or carried into the lake on silt or clay particles. Excess nutrients often boost plant growth, particularly algae or free-floating aquatic plants.                       PLEASE MARK AS BRAINLIEST
