The first image at the top is showing a mutualistic relationship.

Here’s why:

• The bacteria use H₂S (hydrogen sulfide) and CO₂ (carbon dioxide) from the environment to produce carbon compounds through chemosynthesis.

• These carbon products are then used by the host snail for nutrition.

• In return, the bacteria get a safe environment to live inside the snail.

Since both the snail and the bacteria benefit, this is a classic example of mutualism.

Let me know if you want help with the second image too!

They could still be on that rock 

Is it really on muturalism or parasitism

Demonstrate to me that is their relationship
