The ultimate source of energy for all organisms on our planet is the sun. (High-energy compounds, especially ATP, are often described as the immediate source of energy.)
Producers obtain their energy from only sunlight while consumers obtain their energy from food. All people and animals are consumers so most organisms obtain their energy from food. A healthy ecosystem has to be balanced.
ultimately either from the radiant energy from the sun or the geothermal heat of the earth.
The sun, one way or another. The sun, one way or another.
Ultimately all organisms depend on sunlight - plants use it for photosynthesis, consequently anything consuming plants relies on it indirectly and anything that then consumes those animals that eat the plants then (again) ultimately relies on the energy of the Sun.
The Sun
The answer is producers because it takes in the sunlight and makes energy for all the other animals in the food web.
All photosynthetic organisms create energy from sunlight.
The sun for energy
The sun.
Ultimately, it all comes from the Sun.
The chemical energy used by most organisms for metabolism and growth ultimately comes from _
Ultimately all organisms depend on sunlight - plants use it for photosynthesis, consequently anything consuming plants relies on it indirectly and anything that then consumes those animals that eat the plants then (again) ultimately relies on the energy of the Sun.
The Sun
Ultimately, all energy originates from the Sun and is passed along the food chain from there. For example... Sun -> Grass -> Cow -> Human
The autotrophs. Basically any organism that makes its own energy through photosynthesis.
The answer is producers because it takes in the sunlight and makes energy for all the other animals in the food web.
All living organisms use energy to carry out daily functions
