Final answer:
Eubacteria typically get energy through photosynthesis and chemosynthesis.
Step-by-step explanation:
Eubacteria typically obtain energy through various metabolic processes. The two main ways in which Eubacteria obtain energy are through photosynthesis and chemosynthesis.
Photosynthetic Eubacteria use sunlight to convert carbon dioxide and water into glucose and oxygen, which they can then use as a source of energy.
Chemosynthetic Eubacteria, on the other hand, obtain energy by breaking down chemical compounds in their environment. They do not rely on sunlight but instead use the energy from inorganic or organic compounds to produce their own food.
