Explanation:
Cooperative interaction is also called as mutualistic interaction. It is defined as an interaction where One that benefits the recipient other than the performing the behavior.
So, in this study a layer of purple photosynthetic bacteria is using sulfide as an electron source. Sulfide is oxidized by these bacteria, which grow in a layer above sediment from which you have isolated sulfate-reducing bacteria that generate sulfide during anaerobic respiration.
These bacteria's are showing cooperative interaction between each other. Where one species producing a product (sulfate reducing bacteria) that serves as food for other species (photosynthetic bacteria).
