BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Food: Archaea are autotrophic(make their own food). They use chemical synthesis to make food.

Detailed explanation-2: -They may get carbon from carbon dioxide (autotroph) or other living things (heterotroph). Most prokaryotes are chemoheterotrophs. They depend on other organisms for both energy and carbon. Many break down organic wastes and the remains of dead organisms.

Detailed explanation-3: -Abstract. The archaebacteria are a group of prokaryotes which seem as distinct from the true bacteria (eubacteria) as they are from eukaryotes.

Detailed explanation-4: -Archaea can be both autotrophic and heterotrophic. Archaea are very metabolically diverse. Some species of archaea are autotrophic.
