- Plankton live in bodies of water
- A bay is a kind of body of water
- Therefore, some plankton live in bays

- Some plankton live in bays
- A factory dumped mercury into a bay
- Therefore, mercury is dumped into a bay with plankton

- Mercury is dumped into a bay with plankton
- Microorganisms change mercury in a bay into a form that plankton can use
- Therefore, mercury is changed into a form that plankton can use in a bay with plankton

- An element is a kind of material
- Mercury is a kind of element
- So, mercury is a kind of material

- In the food chain process some types of plankton have the role of producer
- Producers pass materials they use through the food chain
- So, plankton pass materials they use through the food chain

- Mercury is changed into a form that plankton can use in a bay with plankton
- Mercury is a kind of material
- Plankton pass materials they use through the food chain
- So, mercury is passed through the food chain

Hence, mercury is passed through the food chain
A factory in Japan had been dumping mercury into Minamata Bay. Certain microorganisms in the water were able to change the mercury into a form that the plankton could use. Which most likely happened next?
