Question

What does it mean when we say that cyanobacteria are photoautotrophs?

1) They can produce their own food using sunlight as an energy source
2) They obtain energy by consuming other organisms
3) They can survive in extreme environments
4) They are capable of both photosynthesis and respiration

Answer 1

Cyanobacteria are photoautotrophs, meaning they can produce their own food using sunlight as an energy source through photosynthesis.

Step-by-step explanation:

When we say that cyanobacteria are photoautotrophs, it means that they can produce their own food using sunlight as an energy source. They are able to carry out photosynthesis, in which they use light energy to convert carbon dioxide and water into carbohydrates. As a result, cyanobacteria can survive and thrive in environments with access to sunlight.
