From dead and decay matter.
The two basic elements necessary for life to exist on a planet are water and carbon. Water is essential for biochemical reactions to occur, and carbon is the building block of organic molecules that make up living organisms.
Organisms that must take in organic molecules for both energy and a supply of carbon are known as heterotrophs. This group includes animals, fungi, and many bacteria and protists. Heterotrophs rely on consuming other organisms or organic matter to obtain the necessary nutrients and energy for their growth and metabolism. In contrast, autotrophs can produce their own organic molecules using inorganic sources, such as sunlight or carbon dioxide.
Carbon, hydrogen, nitrogen and oxygen
Carbon. Life on Earth is based on the complex chemistry of Carbon.
Molecules based on carbon are the major components of living organisms. These organic molecules include carbohydrates, lipids, proteins, and nucleic acids, which are essential for cellular structure and functions in organisms. Carbon's unique ability to form diverse bonds allows for the complexity and diversity of life on Earth.
No, inorganic molecules do not contain carbon and are typically associated with non-living organisms or substances. Organic molecules, on the other hand, are carbon-based and are typically associated with living organisms.
carbon. These elements are abundant in living organisms because they are key components of essential biological molecules such as proteins, nucleic acids, lipids, and carbohydrates. These molecules are necessary for processes such as growth, energy production, and genetic information storage in living organisms.

The two basic elements necessary for life to exist on a planet are water and carbon. Water is essential for biochemical reactions to occur, and carbon is the building block of organic molecules that make up living organisms.
The three elements constantly recycled through living organisms are carbon, nitrogen, and oxygen. Carbon is essential for organic molecules, nitrogen is important for building proteins and nucleic acids, and oxygen is necessary for respiration and energy production.
Carbon and hydrogen
Organic molecules contain both carbon and hydrogen atoms. These molecules are the building blocks of life and are essential for all living organisms.
Heterotrophs obtain carbon molecules by consuming other organisms or organic matter. They break down the complex organic molecules into simpler forms through processes like digestion and cellular respiration to obtain the carbon they need for growth and energy production.
