A team of marine biologists observe that an inland sea is covered with a green slime. They also observe that besides fishing, the local population
practices large-scale farming in the area. In what possible way can farming be responsible for the state of the lake?
A.
Nutrients from fertilizers on the farm wash off into the lake and cause the green slimy algal bloom
B.
Pesticides from the farm wash off into the lake, causing algae to die and producing a green slime.
C.
D.
E.
Plants growing in the farm increase the chlorophyll levels in the ground, which runs off into the lake, causing the green slime.
The plants in the farm deplete the lake of nutrients and kill off microscopic organisms, causing the green slime.
The green slime in the lake is a toxin produced by pesticides that run off into the lake.
