Because the sun is how plants feed, and plants are what what first level consumers eat and so on.
After the sun in the food chain comes producers, which are organisms that can make their own food using sunlight through photosynthesis. These producers are then consumed by primary consumers (herbivores), which are in turn eaten by secondary consumers (carnivores/omnivores) and so on.
In most food chains, yes. However, some food chains, such as those around undersea vents, have other primary sources of energy.
The sun is at the base of the food chain because it provides energy for photosynthesis, which plants use to produce food. Plants are then consumed by herbivores, which are subsequently consumed by carnivores, creating a flow of energy through the food chain. Without the sun's energy, the food chain would collapse.
The sun is referred to as the primary source of energy in a food chain, as it provides light and heat for plants to undergo photosynthesis, which is the basis of all food chains on Earth.

The food chain begins with the sun. The flow of energy for everything on Earth begins with the sun. Sun - Producer - Consumer - Decomposer
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.
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.
Plants and vegetables that use the sun's energy to make food are called autotrophs or producers. They undergo photosynthesis, a process in which they use sunlight, water, and carbon dioxide to produce sugars as a source of energy.
a food chain always begins with all sorts of energy (If you are reading this answer do not think it could be 100% right) I am not your science teacher!
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.
a producer is something that uses the sun for there food and other animals eat them (ps proudcers always start at the begining of the food chain) :))))))))))))

The sun energizes the producer to produce food.
The sun
Because when you eat you get energy and a food chain tells you which animal eats what
Food chains go about this way. Plants take energy from the sun. Then a herbivore eats it while a carnivore awaits but when animals die, the rot, so decomposers like worms and fungi clean it up, but the main start of a food chain is when you get a plant to take energy from the sun.
