Elena-2011 [213]

Answer;

Organisms capture energy from the environment.

Explanation;

-Organisms Capture & Store Free Energy for Use in Biological Processes.

Autotrophs capture free energy from physical sources in the environment.

-Photosynthetic organisms capture free energy present in sunlight.

-Chemosynthetic organisms capture free energy from small inorganic molecules present in their environment, and this process can occur in the absence of oxygen.

Heterotrophs capture free energy present in carbon compounds produced by other organisms.

-Heterotrophs may metabolize carbohydrates, lipids, and proteins by hydrolysis as sources of free energy.

-Fermentation produces organic molecules, including alcohol and lactic acid, and occurs in the absence of oxygen.
