Question

what role do fertilizers play in industrial agriculture?
they increase crop yields significantly.
they are used only in organic farming.
they are not used in monocultures.
they replace the need for water.

Explanation:

Industrial agriculture relies on high crop outputs, and fertilizers supply essential nutrients (nitrogen, phosphorus, potassium) to soil that gets depleted from intensive farming, directly boosting yields. The other options are incorrect: fertilizers are widely used in industrial (not only organic) farming; monocultures (a key feature of industrial agriculture) heavily use fertilizers; and fertilizers do not replace the need for water, as crops still require water for growth.

Answer:

They increase crop yields significantly.
