Either a sun or producer e.g grass and plants
the producers
the sun
All food chains flow of energy start from the sun.
They all have a flow of energy. The amount of energy available decreases as the food chain increases.
Interconnected food chains are known as food webs. A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains.
When all food chains in a habitat are joined together in some way, they form a food web. They are normally several food chains all joined up together, and may include the same predator or prey more than once in a food chain. Food webs are slightly more complex than food chains, and may sometimes be harder to read and understand. hope this helps
No, all food chains must start with a producer that harvests energy from the sun, and distributes it throughout the ecosystem.

You can't. ALL food chains start with a plant such as grass or fruit from a tree.
It should start with the sun.
Without the producers, the food chains could not exits.

If decomposers were not t the end of all food chains then the food chains would not be able to work. This is because the nutrients would not be returned to the producers.
They all have a flow of energy. The amount of energy available decreases as the food chain increases.
Because the sun grows plants and plants feed animals and animals continue the food chain.
Food chains start with green plants because only green plants are able to convert the suns energy into sugars that all creatures including plant need to grow.
