The correct answer is - hierarchical

A hierarchical database model is a data model where the data is organized into a tree like structure. The data is stored as records and these are connected to one another through links.
Direct Values - these are resources that are gathered from plant and animal sources. Examples of these are grains, fruits, vegetables, milk, eggs, fuel, wood, rubber and many others. If they are harvested and consumed directly, they are called consumptive value, and those that are marketed or sold are called productive value.
Indirect Values - these are the benefits of biodiversity that are not easily quantifiable such as supporting other biological life, social and aesthetic value and environmental service value.
The correct answer is b. Release of short-chain fatty acids.
The intestinal microflora is complex ecosystem which contains over 400 bacterial species.That microflora is capable of fermenting indigestible carbohydrates (dietary fiber) to short-chain fatty acids such as acetate, propionate, and butyrate.
Assuming this is the question that has the four different possible answers, the answer is in fact B: The mouth. Otherwise, I would just say that <em>Any area with said decreased light penetration is going to have less diversity of plant life.</em>
