Which of the following statement is NOT true of symbiosis?
A. Symbionts must be living B. It is an association of 'give and take' C. The association may involve two plants D. Association between two similar species E. Symbionts derive mutual benefit
Correct Answer: D
Explanation
The correct answer is:
D. Association between two similar species
Symbiosis refers to a close, long-term relationship between two different species, not two similar species. In symbiotic relationships, the species involved can be quite different from one another and can benefit in various ways, such as mutualism (both benefit), commensalism (one benefits, the other is unaffected), or parasitism (one benefits at the expense of the other).
