What is a cellular respiration, autotrophic nutrition, heterotrophic nutrition, heterotrophic respiration?

i need these answer for my livng e regents please someone help me!

Cellular respiration is the process by which glucose or any energy containing organic compound is converted into ATP. It is either aerobic or anaerobic.

Autotrophic nutrition refers to organisms that can carry on photosynthesis or chemosynthesis to completely supply their nutritional needs.

Heterotrophic nutrition refers to non photosynthetic organisms and the way they secure food for survival.

Heterotrophic respiration is the form of respiration by which organic matter is converted back into CO2.

Cellular respiration is the respiration that takes place in cells at all times. Glucose is broken down in cells by aerobic or anaerobic respiration that is either used as energy or stored as ATP(adenosine triphosphate). A short defintion would be-- Cellular respiration describes the metabolic reactions and processes that take place in a cell or across the cell membrane to release biochemical energy from nutrients and then release waste products. The reactions involved in respiration are catabolic reactions that involve the oxidation of one molecule and the reduction of another.

Before autotrophic nutrition, you must know what autotrophs are- they are organisms that can produce their own food eg-green plants. So, autotrophic nutrition must be the way they produce their own food....

Heterotrophs are organisms that cannot produce their own food and depend on primary producers for it. So the third is how they feed........


No idea about the last

Best of luck
