    Since producers are one which introduce energy source or organic food(
    food or energy is called trophic) for metabolism and development of the
    ecosystem they are placed at first level. They are capable of synthesize
    organic matter( Like Glucose) from inorganic source( like CO2, SO2)
    with the help of sunlight( as in plants and algae) or by chemical
    energy( as in chemo autotrophs).

    That's because it's they who provide the basic food to members of the
    secondary,tertiary,quarternary & top carnivore levels.That means
    that except the top carnivore,all other members of the other trophic
    levels will ( not quite essential - especially for carnivores) have to
    depend on the first trophic level.If by chance this dies off,then the
    others just cannot exist.

    Because the main source of every food chain is the sun and only
    producers are capable of using the sun to create energy.
