Monera : This includes prokaryotes, they are unicellular and lack a true nucleus and also the membrane bound organelles. They obtain their nutrients through absorption and photosynthesis.

Protista : They include eukaryotic organisms. They are generally unicellular; they have a variety of modes of nutrients like absorption, ingestion and photosynthesis.

Fungi : They are eukaryotes that have a cell wall made of chitin. They are multicellular except for the yeast. Their mode of nutrition is absorption and they are fungal organisms.

Plantae : They are multicellular eukaryotes. They have a cell wall of cellulose. They are autotrophs, that is they perform photosynthesis. They are terrestrial organisms that play a role in the food chain.

Animals : Animalia comprises eukaryotic, multicellular organisms with no cell walls. Their mode of nutrition is ingestion and digestion.
