Answer:

D. Chemoautotrophs

Explanation:

Autotrophs in plain are organisms that synthesize their own food while hetrotrophs are organisms that do not synthesize their own food.

Chemotrophs (Chemoautotrophs and Chemohetrotrophs) are a group of organisms that obtain their energy through the oxidation of inorganic molecules, These organisms require carbon to survive and reproduce.

Chemoautotrophs are able to produce inorganic molecules by the fixation of CO2 from their immediate environment. The energy required for this process is got from Nitrogen, Magnesium, Sulphur etc.

Chemohetrotrophs are a class of chemotrophs that are unable to synthesize their own food but rather ingest complex molecules like carbohydrates from the environment.

Phototrophs are a group of organisms unlike chemotrophs that depend on the source of light or sunlight for synthesizing its food or organic molecules.

Photoautotrophs are basically photosynthetic plants which are able to carry out photosynthesis ie the conversion of CO2 and H2O to give Glucose and Oxygen in the presence of sunlight.

Photohetrotrophs are a class of organisms that do not synthesize their own food but rely on other organisms or already made organic molecules.

Explanation:

PMR is a healthy coping skill normally learned in any kind of psychiatric business. For example, I learned PMR while I was inpatient at a behavioral health unit. The way we did PMR was that we'd sit up in our chairs and start from the toes and on up. We squeezed our toes together for a few seconds and then released and then we'd do it a second time. After the toes, it would move up to the feet and we'd use the same process for that and for the rest of the joints.

Outline the biochemical pathways which enables cells to produce energy using glucose and oxygen
Eduardwww [97]

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.

<h3>What is respiration?</h3>

Respiration is the process in which cells use oxygen to break down sugar in order to obtain energy. Glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation are the stages of cellular respiration.

So we can conclude that Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP.
