Answer 1

Food chain respresents a feeding relationship where one organism feeds on other. A food chain always begins with the producer. Producers are usually plants. Primary consumers feed on the producers. E.g., Grasshopper feeds on grass. Secondary consumers feed on primary consumers. E.g., Frogs feed on the grasshoppers. Further the tertiary consumers feed on the secondary consumers and the quaternary consumers feed on the tertiary consumers.
