How do autotrophs obtain energy? How do heterotrophs obtain energy?
antiseptic1488 [7]
Autotrophs, by definition, are organisms that are able to internally manufacture their own food. Autotrophs, also known as producers, are organisms that obtain their energy by converting light energy into chemical energy, via photosynthesis. Photosynthesizing plants are an example of autotrophs. 

Heterotrophs, by definition, are organisms that are unable to internally manufacture their own food. Heterotrophs, also known as consumers, are organisms that obtain their energy by consuming other organisms. Humans are an example of heterotrophs.

Why is your respiratory system necessary for your body to live
Sonja [21]

Answer:

The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.

Explanation:

Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.

The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).

This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.

  • The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
  • CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.

Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.
