The sun because it gets its enegry from it to make food
Glucose is the external fuel of choice used by cells as a ready source of energy. Cells break down glucose through a series of metabolic pathways to produce ATP, the primary energy currency of the cell.
A level in a diagram based on the organism's source of energy refers to trophic levels, which represent the different positions in a food chain or food web. Organisms that obtain energy from the same source, such as producers, primary consumers, secondary consumers, etc., are organized into these levels to demonstrate the flow of energy through an ecosystem.
A bacterivore is an organism which ingests bacteria either as food or an energy source.
An organism that is the source of all food in an ecosystem is called a producer. A consumer gets its energy by feeding on other organisms.
External digestion is a process used by some organisms such as fungi and spiders to break down food outside of their bodies. In this process, enzymes are secreted onto the food substance to break it down into smaller molecules that can be absorbed by the organism. This allows the organism to extract nutrients from the food source without ingesting it.

An organism that can provide a source of energy for a virus or another organism is called a host. The host organism can provide resources and nutrients necessary for the growth and reproduction of the virus or another organism that depends on it for survival.
Other organism
it is a source of energy
The sun is the major external source of energy.
A chemosynthetic organism uses sulfur or other elements as a source of energy.
solar energy
Solar energy :)
light energy
A chemosynthetic organism uses sulfur or other elements as a source of energy.
i think it is a decomposer
Depends on the source
