It is the biotic source; input; energy
the sun
the sun because it is what makes plants grow which are the producers and the beginning of the food chain.
The ultimate source for living thins is the sun. This is because the sun provides things on the absolute bottom of the food chain with food. They are then used as food for the next living thing on the food chain. Things on the bottom of the food chain are called producers. They perform photosynthesis to convert the suns light into useable energy. Organisms the can create their own food are called autotrophs.
the main source of energy of all food chain is the sun.Basically it provides the energy for green plants to overcome the process of photosynthesis, the making of food.
Energy enters a food chain in the form of sunlight, and leaves the food chain in the form of heat.
This is called a food chain. Food Chain- The moving of energy from one organism to another
The ultimate source of energy in any ecosystem is the sun. Solar energy is converted into chemical energy through the process of photosynthesis by plants, which then gets transferred through the food chain to all other organisms in the ecosystem.
how is the energy in a food chain different form the energy of the wind?
Depending on the food chain you look at, plankton or the sun. Phytoplankton capture the energy from sunlight through photosynthesis. The sun is the ultimate source of energy, but it is not an actual member of a food chain or web. Phytoplankton are at the beginning of the ocean food chain or web.
Energy can be lost in a food chain by heat or waste.
who gets the least amount of energy in the food chain
