What is the 2 kingdom system?

How did Robert Whittaker classify organisms into kingdoms?
Amongst these, the Five Kingdom Classification proposed by Robert Whittaker stood out and is widely used. Whitaker proposed that organisms should be broadly divided into kingdoms, based on certain characters like the structure of the cell, mode of nutrition, the source of nutrition, interrelationship, body organization, and reproduction.
How are kingdom Fungi different from other kingdoms?
Heterotrophic, Multicellular and Eukaryotic organisms are grouped under Kingdom Fungi. Their mode of nutrition is saprophytic as they use decaying organic matter as food. They have cell walls, which are made up of a substance called Chitin. Fungi also form a symbiotic association with some blue-green algae.
