What is the primary energy source for most organisms?

The primary energy source for most organisms is glucose, which is obtained through the process of photosynthesis in plants or by consuming other organisms. Glucose is broken down in cells through cellular respiration to produce adenosine triphosphate (ATP), which is used as a direct source of energy for cellular activities.

Where does all energy for most organisms on earth come from?

The primary source of energy for most organisms on Earth is the sun. Through the process of photosynthesis, green plants and algae convert sunlight into chemical energy in the form of glucose, which is then used by other organisms as a source of fuel. This process forms the basis of the food chain and provides energy for most living things on Earth.


What is the ultimate source of energy for most organisms and how is this energy captured so it is useful in a food chain?

The ultimate source of energy for most organisms is the Sun. This energy is captured by plants through photosynthesis, where they convert sunlight into chemical energy stored in sugars. Other organisms then consume these plants (or organisms that eat the plants) to obtain energy and nutrients.


What is the main source of energy for most ecosystems?

The main source of energy for most ecosystems is the sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert sunlight into chemical energy that fuels the ecosystem. This energy is then passed along the food chain as organisms consume each other.


The most common molecule used in cellular respiration of all organisms as a source of energy is?

Sugar


What is the source of all energy?

The Sun is the primary source of energy for most living organisms on Earth. Solar energy is converted into chemical energy through processes like photosynthesis, which then fuels the food chain.


What source do most organisms on earth get their energy?

Most organisms on Earth get their energy from the Sun through the process of photosynthesis. Plants, algae, and some bacteria are able to capture sunlight and convert it into chemical energy that sustains themselves and other organisms in the food chain.


Of the four classes of biologically significant macromolecules the one that provide the main source of energy for most organisms are?

The class of biologically significant macromolecules that provides the main source of energy for most organisms is carbohydrates. Carbohydrates are broken down during cellular respiration to produce ATP, which is the main energy currency of cells.


What carbohydrate is a main energy source for most organisms?

The most common carbohydrate energy source for most organisms is glucose. Other common sugars are fructose and galactose, but glucose by far is the most common. Glucose is not only the most common as a simple sugar (monosaccharide), but also as the basic link in larger polysaccharides, including the disaccharide sucrose and the polymers glycogen and amylose.


What class of organic molecule is used as an immediate energy source for most organisms?

Carbohydrates, such as glucose, are the class of organic molecules used as an immediate energy source for most organisms. Glucose is readily converted into ATP through cellular respiration to provide the energy needed for cellular functions.
