Thermus aquaticus is a species of bacteria found living in the hot springs in Yellowstone National Park. Hot springs typically are areas characterized by low oxygen levels, low light levels and high concentrations of sulfur and calcium carbonate.

In what way do bacteria living in or near hot springs most likely make food?

Through the process of photorespiration by using oxygen and light energy to produce carbon dioxide.

Through the process of radiosynthesis by using gamma radiation and melanin to create energy for growth.

Through the process of chemosynthesis by combining hydrogen sulfide with oxygen and carbon dioxide to make carbohydrates.

Through the process of photosynthesis by using energy from the sun, water and carbon dioxide to make glucose.

None

23.

An algal culture is grown and two different species of protozoans A and C are inoculated into the culture which feeds on algae. For the time period during which algae is not acting as a limiting factor, protozoan A reproduces asexually once every hour and protozoan C reproduces one every 1.5 hours.

The most likely observation is

Both populations of protozoans will increase in size initially, but then Protozoan C will die off from the culture.

The algae will rapidly evolve to avoid predation.

The protozoans will evolve to have a mutualistic relationship.

The algae will die off from the culture due to overfeeding.

None
