cannot be absorbed by roots
C
can be carried into local water supplies
D
cause atmospheric pollution
Explanation: 

Detailed explanation-1: -Fertilizers used to improve lawns and gardens can interfere with the equilibrium of an ecosystem. Because, they can be carried into local water supplies. Explanation: Nutrients present in the fertilizers and manures could enter the lakes through the process of run – off.

Detailed explanation-2: -When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.

Detailed explanation-3: -When fertilizers are added, they make the water polluted leading to the excessive growth of plants on the surface of freshwater. Algal bloom leads to the degradation of water quality and a decrease in oxygen by which organisms start dying. Over the year, the lake was finally converted into the land.
