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
Option (III) .Cephalization, the clustering of neurons and interneurons in the anterior part of the animal, is apparent in <u>Planaria.</u>
What is planaria?
- Planaria is a genus of planarians in the family Planariidae.
- When an individual is cut into pieces, each piece has the ability to regenerate into a fully formed individual.
- Currently the genus Planaria is defined as freshwater triclads with oviducts that unite to form a common oviduct without embracing the bursa copulatrix and with an adenodactyl present in the male atrium.
- The testes occur along the whole body.
- Planaria originally have habitats in dark, murky water which results in such sensitivity .
- They are also sensitive to other stimuli such as chemical gradients, vibration, magnetic and electric fields .
- Their central nervous system includes the anterior (head, brain and eyes) and middle (abdominal trunk and pharynx).
