The primary source of energy for almost all food chains is the sun. The usual series is that the sun provides energy to plants that provide to other creatures. Some ecosystems rely on other energy sources however. For instance some deep ocean ecosystems rely on geothermal energy harvested by bacteria.

Without sunlight, plants would not grow. If plants could not grow there would be nothing for herbivores, and subsequently carnivores and omnivores, to eat.

What is the energy source in a food web or food chain?
plants
Where does the energy come from that starts a food web?
The sun is the source of all energy in a food web. The primary producers - plants - use the sun's energy to produce organic compounds. Some producers eg micro-organism use inorganic chemical reactions to produce energy
What role does the sun play in a food web?
Sun plays the source of energy in a food web.
What is plankton on a food web?
Primary production, create energy, provide food, and so on.
Write out one food chain from the food web below Begin with the primary energy source and include at least 3 organisms?
Sun, Tree, Insect, Lizard, Snake, Hawk
Describe how energy enters a food web through plants?
Energy enters a food web by photosynthesis: the sun is the primary energy source, and autotrophs (mainly plants) 'fix' the energy & use it to convert carbon dioxide into foods which are then eaten by organisms further up the food chain.
In a food web what is the source of energy?
In most food webs the Sun is the ultimate source of energy. Some food webs start with chemotrophs and in those cases the source of the energy are chemicals often from underwater volcanoes.
What is the ultimate source of energy in any food chain or web?
the sun
What is the most important source in the food chain?
The Sun
What is used to indicate the flow of energy in food chain or web?
What is used to indicate the flow of energy in a food chain or web
How energy flows through a food chain and a food web?
Energy flows up a food chain, from the primary producers to the primary consumers, to the secondary consumers, up to the tertiary and then quaternary consumers. Energy flows when one organism eats another.
Transfer of food energy from one source to another in stages is called what?
This is called a food chain. Food Chain- The moving of energy from one organism to another
