Step 1: Understanding the Concept
The chart gives the relative number of species of animals, plants, fungi, protists and eubacteria. The order from largest to smallest is animals, plants, fungi, protists, eubacteria.
Step 2: Check statements
Animals have the largest sector, so the first statement is true. Plants are second, so the second is true. Fungi exceed protists and eubacteria, so the third is true.
Step 3: Find the incorrect one
Eubacteria have the smallest sector, even smaller than protists. The statement that eubacteria are less than all others except protists is therefore incorrect.
Final Answer:
The statement about eubacteria being less than all except protists is incorrect.
\[ \boxed{\text{(D) }\text{Eubacteria are less than all others except protists.}} \]
