    C) Primary consumers

    Correct Answer: A

    Solution :

    Consumers are the heterotrophic component of the ecosystem. They cannot manufacture their own food. Therefore, they depend upon substances synthesized by the producers. Plant debris and animal waste products are decomposed by micro-organisms such as fungi and bacteria which are considered as micro-consumers. These are also known as decomposers. Macro-consumers include herbivores and carnivores.
