Question

Though Heinrich Anton de Bary was the first to formalize the idea of symbiotic interactions, his categories are probably not the best scheme to describe these associations. Why?

A. Commensalism (one of his categories) never occurs in nature.
B. de Bary's categories don't cover situations such as synnecrosis or ammensalism.
C. de Bary's categories are too "neat" and assume that a relationship is relatively fixed in nature.
D. Both B and C are correct.

Answer 1

D. Both B and C are correct.

Step-by-step explanation:

Heinrich Anton de Bary was the German botanist who is known for his work on the fungi and algae causing plant disease.

He coined the term "symbiosis" for the unrelated species which live together and mutually benefit others as he studied the formation of lichen, the symbiotic relationship between the fungus and the algae.

There were many limitations to the concept of the symbiotic relationship introduced by the Bary as his work was based on the assumptions that the interaction between the organism is fixed and has the amensalism interaction was not mentioned by him.

Thus, Option-D is the correct answer.
