The primary energy source for most living systems is nutrients. Nutrients are elements and compounds that organisms consume and require for survival. Organisms need several dozen naturally occurring chemical elements to survive; among these are nitrogen, carbon, and phosphorus.
Type your answer here... sunlight
carbon dioxide in the atmosphere
The sun
glucose
The answer is nuclear fusion!! (:
The trophic level that contains the organisms that are the source of all chemical energy used in an ecosystem is called the producer level. This level contains the organisms that can make their own food.
A sipmple sugar, that is an important energy source in living organisms and is a component of many carbohydrates
Plant photosynthesis is the primary source of nutrients in every ecosystem. Deep in the ocean, where little or no sunlight is present, photosynthesis is impossible. Thus, organisms in deep water ecosystems depend on detritus (discarded waste) and other organic matter that drifts down from (and is generated) nearer to the surface, or on species that migrate back and forth.
the ultimate source of energy for all living organisms is the sun
the sun
glucose

The sun and the sunlight are the main things for all living things.

population is the primary evolutionary unit of any living organisms
That is the glucose. It is a monosaccharide
The sun.
Living organisms. Fossils too.
