The ultimate source of all energy on earth is light from the sun. Plants use that energy, along with carbon dioxide from the air and nitrates from the soil, to create sugars and lipids (fats) as well as amino acids (ingredients for DNA) through the process of photosynthesis.
Without photosynthesis, there would be nothing of nutritional value (energy) in plants for animals to digest and turn into protein (muscle tissue). Even carnivores who eat only meat depend on plants as their prey would not be alive without energy they get from eating plants, which in turn comes from light from the sun.
The sun is the ultimate source of energy for almost all earth ecosystems.
Plants are the ultimate source of energy because they undergo photosynthesis, converting sunlight into chemical energy in the form of glucose. All organisms, directly or indirectly, rely on plants for energy through the food chain. Without plants, energy transfer within ecosystems would not be possible.
The ultimate source of energy for nearly all surface terrestrial and shallow water ecosystems is the sun. Through the process of photosynthesis, plants and other autotrophs convert sunlight into chemical energy that is then passed on to other organisms in the ecosystem.
The ultimate source of energy for living systems on Earth is the sun. Plants and some microorganisms use sunlight to perform photosynthesis, converting solar energy into chemical energy stored in organic molecules. This energy is then passed through the food chain as organisms consume other organisms.

The energy source of all ecosystems is sunlight. Sunlight is captured by plants through photosynthesis, which converts it into chemical energy that is then passed on to other organisms through the food chain.
