Contrast the two different methods of locomotion that a Paramecium can utilize depending on if it needs, or wants, to move slow or fast
Locomotion in paramecium is through metaboly and ciliary beating.
What is locomotion?Locomotion refers to the ability to love from place to place.
Paramecium is a unicellular eukaryotic organism found in aquatic habitats.
Paramecium performs locomotion by two methods
metaboly or body contortions andby ciliary beats.Metaboly is a type of movement where the paramecium squeezes itself through narrow passages by changingthe structure of its protoplasm.
Metaboly is a temporary and slow locomotion im paramecium.
Ciliary beating is a fast method of locomotion in paramecium through forward or backward beating of the cilia.

Answer/Explanation:
Nocturnal ⇒ occurring or active at night
Reason 1; During the day earthworms mostly stay in their burrows underground
Reason 2; At night they come up on to the surface to feed
Knowing that; They have receptor cells in their skin that are sensitive to light and touch. Worms breathe through their skin. It's imperative for them to stay cool and moist in order to continue breathing. If they came out during the day the sun would dry them out and they would not be able to breathe.
