In a green plant
There are photosynthetic organisms beside plants(Cyanobacteria, etc.). The energy for photosynthesis comes from the Sun. There are also organisms that can get energy from chemicals. Such as chemicals released from hydrothermal vents. That energy may have ultimately came from other stars that exploded long ago(elements made in the core of those stars that is now generating heat in the Earth via nuclear decay). So for life as we know it all food starts with energy directly or indirectly from stars. That energy came from nuclear fusion of light elements. Those light elements came from the Big Bang.
,ultimately, it comes from the sun.
Energy enters a food chain in the form of sunlight, which is converted into chemical energy by producers through photosynthesis. When energy leaves a food chain, it is typically in the form of heat after being used by organisms for metabolism and daily functions.
Producers, such as plants, are the organisms in a food chain that add energy to every part of the chain. They do this through the process of photosynthesis, where they convert sunlight into energy that can be used by other organisms in the food chain.
The transfer of food energy from one organism to another in stages is called a food chain. In a food chain, energy is passed from producers (plants) to primary consumers (herbivores) to secondary consumers (carnivores) and so on. Each transfer of energy represents a trophic level in the ecosystem.
The organism that eats the producer in a food chain is known as a primary consumer or herbivore. These organisms feed directly on plants or algae for energy.
The Sun!
Because when you eat you get energy and a food chain tells you which animal eats what
,ultimately, it comes from the sun.
Sun
i think it's Ocean waves
how is the energy in a food chain different form the energy of the wind?
Energy can be lost in a food chain by heat or waste.
Energy enters a food chain in the form of sunlight, which is converted into chemical energy by producers through photosynthesis. When energy leaves a food chain, it is typically in the form of heat after being used by organisms for metabolism and daily functions.
The energy flux of a food chain goes from producer to decomposer. The energy flux along the food chain is always unilateral.
Producers, such as plants, are the organisms in a food chain that add energy to every part of the chain. They do this through the process of photosynthesis, where they convert sunlight into energy that can be used by other organisms in the food chain.
