The correct situation that has occurred in the scenario you provided is:
A producer is eaten by a primary consumer which is then eaten by a secondary consumer. The secondary consumer is then eaten by a tertiary consumer.
Here's the breakdown:
- The small fish represents a primary consumer because it eats part of a plant, which is a producer.
- The larger fish that eats the small fish is a secondary consumer.
- The shark that eats the larger fish is a tertiary consumer.
So the sequence is:
- Producer (plant) → Primary Consumer (small fish) → Secondary Consumer (larger fish) → Tertiary Consumer (shark).
