Yes, most species are they feed on plant material. However, there are some species that are carnivorous and therefore not primary consumers.
Secondary Consumer
The caterpillar is the primary consumer. If an organism eats plants, it is a primary consumer. If it eats other animals, it is a secondary or tertiary consumer.

Primary consumers in an ecosystem are the animals that eat and get their energy from producers (plants/vegetation etc.) for example: Cabbage (Producer) ----> Caterpillar (primary consumer). Primary consumers are mainly classed as herbivores. A secondary consumer would be something that then eats the primary consumer.

the role of the robin is of a secondary consumer
yes
It's a primary consumer. Primary consumers eat plants (which are producers). Secondary conusmers are carnivores that eat the primary (and sometimes other secondary) producers. Another example: Gazelles eat plants (making them a primary consumer), Cheetas eat gazelles (making them secondary consumers) since they eat the thing that eats plants. Hope that helps!
