Metabolic types include assimilation and alienation.

The types of alienation include aerobic, anaerobic and facultative anaerobic.

The ways of assimilation can be divided into autotrophic and heterotrophic.

Take corn as an example, its assimilation type is autotrophic, alienation type is aerobic and metabolism type is autotrophic aerobic.

Extended data:

I. Alienation

1, aerobic type

Most animals and plants need to live in an oxygen-rich environment. In the process of alienation, they must constantly absorb oxygen from the external environment to oxidize and decompose the organic matter in their bodies and release energy to maintain their own life activities. This metabolic type is called aerobic type, also called aerobic respiration type.

2. Anaerobic

Such organisms include some animals, such as lactic acid bacteria and parasites that live in animals. In the absence of oxygen, they can still oxidize the organic matter in the body and obtain the energy needed to maintain their own life activities. This type of metabolism is called anaerobic, also known as anaerobic respiration.

3. facultative anaerobic type

This organism carries out aerobic respiration under the condition of sufficient oxygen, completely decomposes organic matter into carbon dioxide and water, and incompletely decomposes organic matter into lactic acid or alcohol and water under the condition of lack of oxygen. A typical facultative anaerobic organism is yeast.

Second, assimilation

1, autotroph: an organism that can synthesize its own organic matter from inorganic matter belongs to autotroph. Such as cyanobacteria, nitrifying bacteria and green plants.

2. heterotrophs: Organisms that can only ingest ready-made organic matter from outside belong to heterotrophs. Such as most animals and fungi.
