In a pond, the primary producer is a green algae, the primary consumer is the crustacean, the secondary consumer is the bluegill fish, and the tertiary consumer is the small mouth bass. what changes can be expected in the pond if the crustaceans are killed with pesticides?

a. the small mouth bass population will increase.

b. the crustacean population will eat something else.

c. the green algae population will probably increase.

d. the bluegill population will probably increase.

Explanation: The green algae population will increase because if the crustaceans are killed, there is no consumption of algae hence resulting in increased levels of algae.

After that the blue gill fish that is the consumer of crustaceans will also be affected, their numbers will start to reduce with time and they might die off unless they move to another habitat so the option "D" is wrong

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
