Identify the correct order of known species of organisms by their increasing numbers.

Step-by-step solution

The approximate number of known and described species for different groups of organisms is as follows: Eubacteria: 10,000 Protists: 60,000 Fungi: 100,000 Plants: 300,000 Animals: > 1,200,000 Arranging them in increasing order of their known species numbers, we get: Eubacteria Protists Fungi Plants Animals. Answer: Eubacteria - Protists - Fungi - Plants - Animals
