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).

True or false: competition between organisms involves both biotic and abiotic factors
Mamont248 [21]
I believe it’s true, since Competition will occur between organisms in an ecosystem when both try to use the same resource and the resource is in limited supply. Animals compete for food, water and space to live. Plants compete for light, water, minerals and root space.
