The food chain begins with the sun. The flow of energy for everything on Earth begins with the sun.
Sun - Producer - Consumer - Decomposer
a producer, which is a plant which is always at the beginning of the food chain.
A producer is at the beginning of every food chain. Usually it is a green plant, which can use the energy in sunlight to produce food. That food supports all the other organisms. There is no food chain until food is produced.
The consumer is always at the top, or end of the food chain. Producers are at the bottom, or beginning of the food chain.
Producers
Producers are the beginning of a simple food chain. Producers are plants and vegetables. Plants are at the beginning of every food chain that involves the Sun.
Algae at the beginning of a food chain are considered primary producers. They convert sunlight into energy through photosynthesis, forming the base of the aquatic food web. As primary producers, they provide essential nutrients and energy for herbivores and other organisms higher in the food chain.

the kind that grows
They are microscopic marine plants that are the beginning of the food chain in the ocean.
If you have a food chain then the chain must have a beginning (where the food is made) and an end (where the food is finally all used up). Thius in a food chain the "producers" of the food (the plants) are ALWAYS the start. The plants make food using CO2 from the air, Water from the ground and the energy they collect from Sunlight. It is the passing on of this energy from the Sun that is the chain.
