Answer:
The bacteria will be evenly distributed on the chain of algae
Explanation:
<em>If the component of white light is not separated by a prism, all the components will be evenly distributed in space and as such, equal amount of each component will go to the chain of algae.</em>
<em>The equal amount of each light component that goes to the chain of algae will ensure that there is equal rate of photosynthesis, and hence, oxygen production in each algae. Consequently, the oxygen-requiring bacteria will spread out evenly on the chain of algae without concentrating particularly on any algae.</em>
