• B. Both the assertion and reason are true but the reason is not the correct explanation of the assertion
• C. Assertion is true but the reason is false
• D. Both the assertion and reason are false

Answer 1

The correct option is C Assertion is true but the reason is false

Agroecosystems, are defined as communities of plants and animals interacting with their physical and chemical environments that have been modified by people to produce food, fibre, fuel and other products for human consumption and processing.

Agroecosystems are man-made, which lack the natural diversity but they are very stable and efficient ecosystems in terms of productivity. Agroecosystems contain few seasonal crops and they are the largest man-made ecosystems. So the assertion is true but the reason is false.
