Photoautotrophs Obtain Energy From

Question

Photoautotrophs obtain energy from:
A)light and use carbon dioxide as a carbon source
B)organic molecules and use carbon dioxide as a carbon source
C)inorganic substances and use carbon dioxide as a carbon source
D)light and use organic substances as a carbon source

Accepted Answer

Photoautotrophs are organisms that use light as a source of energy and carbon dioxide as a source of carbon. They are able to produce their own food through photosynthesis, using pigments such as chlorophyll to capture light energy and convert it into chemical energy. This process occurs in plants, algae, and some bacteria. Therefore, option A is the correct choice as it suggests that photoautotrophs obtain energy from light and use carbon dioxide as a carbon source.
