Answer:

D.Predation

Explanation:

Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.

Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.

The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.

Explanation:

When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's  first law of  motion or  law of inertia of motion.

Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.

The more is the mass of the body , the greater will be the inertia.

External force is the force applied by external agents on the body.
