This type of nutrition involves the taking in of solid particles of food which have to be further broken down into simpler particles inside the organism (there are exceptions which are called fluid feeders. Think of at least two of them. Look for answers in the Q & A section). These particles may be big or small.
For example, Hydra and sea anemone are called macrophagous feeders as they take in large pieces of food. Animals like the earthworm and mussels are called microphagous feeders as they take in food which is in very small particles. Earthworms are also called detritivores as they feed on dead plant and animal matter. However, the digestion takes place inside the body and hence they are also considered holozoic. Holozoic nutrition involves ingestion of food, its digestion, absorption and assimilation.
