Question

The mutualism of Azolla-Anabaena is useful for
A) aquaculturalists.
B) corn farmers.
C) rice farmers.
D) tropical forest community succession.

Accepted Answer

The mutualism between Azolla-Anabaena is specifically useful for rice farmers. Azolla provides nitrogen to rice fields due to its symbiosis with the nitrogen-fixing cyanobacterium Anabaena. This symbiotic relationship helps to decrease the use of external nitrogen fertilizers in rice farming, which can be costly and detrimental to the environment. Therefore, it is a sustainable and cost-effective method for rice farmers to yield higher rice production.
