sun
Organisms that eat other organisms for energy are hetreotrophs.
Organisms that photosythesize get their energy from the sun
Organisms get energy by eating autotrophs.
A food chain.The steps by which energy flows among groups of organisms is called an energy pyramid. The energy pyramid shows what organisms get energy from other organisms and how much they get.
The source of energy for most organisms is chemical energy and sunlight.
Organisms that can consume other organisms for energy are known as heterotrophs. This includes animals, fungi, and some types of bacteria. Heterotrophs rely on consuming organic matter to obtain the energy they need for survival.
Parasites
Phytoplankton are photosynthetic organisms. They get their energy from sunlight.
Energy is passed between organisms through food consumption, as organisms obtain energy by consuming other organisms or their products. Energy is also passed between organisms through symbiotic relationships, such as parasitism, where one organism benefits by extracting energy from another organism.
Animals.
Yes, photosynthesis is what converts the light energy from the sun into the usable chemical energy that organisms use.
Energy is essential for organisms to carry out their life processes such as growth, reproduction, and movement. Organisms need energy to maintain their metabolic functions and to provide the necessary chemical reactions for survival. Without energy, organisms would not be able to sustain life.
