The symbol denotes a positive interaction, - denotes a negative interaction, and 0 denotes where individuals are not affected by interacting. The first symbol refers to the first organism mentioned. What interactions exist between cellulose-digesting organisms in the gut of a termite and the termite?

A) +/+

B) +/-

C) 0/0

D) -/-

A) +/+

Explanation:

The form of interaction that exist between cellulose-digesting organisms in the gut of a termite and the termite itself is a +/+ interaction.

This is because the interaction of both organisms is beneficial to each of them. While the cellulose-digesting organisms are able to get their shelter in the gut of the termite, the termite benefits from the presence of these cellulose-digesting organisms by getting their cellulose-containing food materials digested by them.

Hence, it is a mutually beneficial interaction.
