Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines.
Federal crop insurance policies are generally either yield-based or revenue-based. For most yield-
based policies, a producer can receive an indemnity if there is a yield loss relative to the farmer’s
“normal” (historical) yield. Revenue-based policies were developed after yield-based policies, in
the mid-1990s, to protect against crop revenue loss resulting from declines in yield, price, or both.
The most recent addition has been products that protect against losses in whole farm revenue
rather than just for an individual crop.
