The sun.
Without the sun life on earth would soon stop because all available carbon (the basis of all life forms on Earth) would be used up.
A few ecosystems get their energy partially or entirely from geothermal sources. The original source of this energy is radioactive decay heat from isotopes in the crust, mantle, and core.
Both the sun and earth were formed from matter ejected and/or compressed by supernova explosions. So the original source for both the energy from the sun and from radioactive decay heat was supernovas.
Ultimately the original source of all energy was the Big Bang.

What is the original source of an ecosystem?
The original source of an ecosystem is the sunlight that provides energy for photosynthesis, the process by which plants produce food. This energy is then transferred through the food chain as organisms consume one another. Ultimately, this energy originates from the sun.
What level of the food chain has the most energy?
Producers, such as plants and algae, have the most energy in a food chain. They convert sunlight into energy through photosynthesis, making them the primary source of energy that flows through the ecosystem.
What is the major source of energy for the food chain?
The sun is the major source of energy for the food chain through a process called photosynthesis. Plants, algae, and some bacteria capture sunlight to convert it into chemical energy that is then passed on to consumers in the food chain.
How much energy does a primary consumer receive of the original energy from the sun?
A primary consumer receives about 10% of the original energy from the sun. This energy is captured by producers through photosynthesis and passed on through the food chain, with energy decreasing at each trophic level.
What is the energy source of ALL ecosystems?
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.
What is the original energy source?
The original energy source on Earth is the sun. Solar energy fuels life on our planet through photosynthesis, which converts sunlight into chemical energy that sustains plants and, ultimately, all living organisms through the food chain.
What is the original source of energy on the Earth?
The original source of energy on Earth is the Sun. Solar energy is harnessed through processes like photosynthesis in plants, which converts sunlight into chemical energy. This energy is then transferred through the food chain to sustain all life on Earth.
What is the original source of an ecosystem?
The original source of an ecosystem is the sunlight that provides energy for photosynthesis, the process by which plants produce food. This energy is then transferred through the food chain as organisms consume one another. Ultimately, this energy originates from the sun.
What is the original source of all the food energy on earth?
The original source of all food energy on Earth is the sun. Through the process of photosynthesis, plants convert sunlight into energy that is stored in the form of carbohydrates. This energy is then transferred through the food chain as animals consume plants or other animals.
What is the original source of energy for all living things?
The original source of energy for all living things is the sun. Plants capture sunlight through photosynthesis to produce energy-rich molecules that are used as fuel by organisms throughout the food chain.
What is the original source of energy for all the organisms in the food chain?
Crack cocaine.
The original source of energy in a food chain is from the?
The sun its so simple
What level of the food chain has the most energy?
Producers, such as plants and algae, have the most energy in a food chain. They convert sunlight into energy through photosynthesis, making them the primary source of energy that flows through the ecosystem.
What is original source of most energy on earth?
The original source of most energy on Earth is the sun. Solar energy provides the power for various processes like photosynthesis, which is the basis of the food chain and ultimately sustains all life on the planet.
What is the major source of energy for the food chain?
The sun is the major source of energy for the food chain through a process called photosynthesis. Plants, algae, and some bacteria capture sunlight to convert it into chemical energy that is then passed on to consumers in the food chain.
What is the main source of all energy?
The main source of all energy on Earth is the sun. Solar energy is converted by plants through photosynthesis into chemical energy, which is then transferred through the food chain to provide energy for all living organisms.
What is the source of energy for most organism?
water and electricity
