Something can't come from nothing. Energy cannot be created or destroyed. It can only be converted and transferred.
Producers are the only living organisms of earth that are able to convert sunlight to energy. If it was not at the bottom of the energy pyramid, the organisms below it would not exist because they were not getting energy from the producers.

Producer provides food to herbivores in food chain .
A plant is always a producer in the food chain
If algae is the producer in a food chain of the ocean then corn would be a producer in a food chain on land. Any green plant is a producer.
The first level of a food chain should always be a producer of some sort, such as a tree or plant. It is the start of the food chain - and without it, the entire food chain would fall apart and into pieces; as it would disrupt the order of the levels in a food chain.
Phytoplankton and algae such as seaweed form the base of the ocean's food web
Every food chain must start with a producer turning energy into food. You cannot have a food chain until food has been produced. This is usually done by plants with chlorophyll, using the rays of the sun for energy. Once the food has been produced, then you can have a food chain. You can list the consumers who eat the plants and then the ones who eat the plant eaters and then the ones who eat the meat eaters.
The Food Chain refers to every species linked together starting at the top with the "producer" species and ending with the "decomposer" species.
yes because if it wasn't then the herbivore can't eat.
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.
