Observe the diagram and answer the question given below:

Which among the following is not a primary consumer?

Snake

The correct answer is Option (1)- Snake

Primary Consumers: These are herbivores that feed on producers (plants and algae).

• Grasshopper: Feeds on plants, making it a primary consumer.
• Zooplankton: Often feed on phytoplankton (algae), making them primary consumers.
• Caterpillar: Feeds on plants, making it a primary consumer.

Snake: Snakes are typically secondary or tertiary consumers because they feed on primary consumers such as rodents, insects, or other smaller animals. Therefore, a snake is not a primary consumer.
