The body of animals of the phylum Protozoa, such as Paramecium, Amoeba, Euglena, shows ________ grade organisation.

protoplasmic

The correct answer is Option (2)-protoplasmic

The body of animals belonging to the phylum Protozoa, such as Paramecium, Amoeba, and Euglena, shows protoplasmic grade organization.

Explanation:

• Protozoans exhibit a simple and primitive level of organization known as a protoplasmic grade.
• In protoplasmic grade organization, the entire body functions as a single, undifferentiated mass of protoplasm.
• These organisms lack specialized tissues, organs, or distinct cell layers.
• All life processes, including digestion, locomotion, and reproduction, occur within this single cell or mass of protoplasm.

Therefore, the correct answer is protoplasmic.
