    Important roles producers, consumers, and decomposers play in an ecosystem:

    Role of the producer:
    A producer captures energy and stores that energy in food as chemical energy. Producers such as plants have special organelles called as chloroplasts that absorb energy from the sun.
    Example: Autotrophs are producers, that make their own food by photosynthesis process.

    Role of consumers:
    Consumers obtain energy and nutrients from producers as they cannot make their own food.
    Example: Heterotroph is the consumer, such as
    a) herbivore are the primary consumer that eats only plants, such as cows, deer or some insects
    b) carnivores are the secondary consumer that eats only other consumers such as cats, spiders, wolves, hawks etc.
    c) omnivore are the tertiary consumer that eats both plants and animals such as, monkeys, bears, turtles etc.

    Role of decomposers:
    They are organisms that break down dead plant and animal into simple compounds.
    Example: scavengers are decomposers. These animals feed on dead bodies, such as vultures, hyenas etc.
    An ecosystem cannot function without one of these. The role of producers, consumers, and decomposers in an ecosystem :
    The producers in an ecosystem make food on their own by capturing energy from sunlight and make that available to all the other living parts of ecosystems and food chain starts. Food chains explain the flow of energy in an environment that moves from one organism to the next.

    Without primary producers, which are plants consumers and decomposers would not able to live as producers begin every food chain.
    The flow of energy in an ecosystem begins with sunlight which is the ultimate source of all energy on Earth and that energy is absorbed by the producers, which goes to the consumers and then to the decomposers. Then it goes back to the producers to begin the cycle again.
    So, without producers ecosystem cannot function.

    A consumer is a heterotroph that cannot make its own food and eat producers or other organisms for energy. We are in the category of consumers that eat the food that producers like plants made.
    Consumers in an ecosystem balance the food chain by keeping plant populations in a limited number. Without proper balance, an ecosystem would collapse and it will decline all the affected populations.
    So, without consumers ecosystem cannot function.

    Decomposers decompose dead plants and animals matter when they die, such as bacteria is a decomposer.
    Imagine an ecosystem if there were no decomposers. All the wastes and the remains of dead organisms would pile up that will damage the ecosystem. The nutrients within the waste and dead organisms will not go back into the ecosystem and organism will not function properly.
    So, without decomposers ecosystem cannot function.
