The rate of formation of new organic matter by rabbit in a grassland is known as which type of productivity?
Answer & explanation
Correct answer: option 3
The grass that the rabbit feeds on, in the grassland, is the primary producer.
Since, the rabbit is a consumer, the organic matter that is produced by it would be secondary productivity.
Another example of such secondary productivity would be a caterpillar.
Caterpillars feed on the leaves of a plant, which is the producer, and the waste produced by caterpillars is the secondary productivity.
