Crucial to all life is the answer
The given question is incomplete, the complete question is:
Grizzly bears are an integral part of the ecosystems in which they live and thrive. An example of their value to biodiversity includes their role in providing forests with a large amount of nitrogen needed to grow and persist through the consumption of salmon. This is an example of what type of species value?
Select one:
a. None of the above
b. Direct
c. Indirect
d. Cultural
Answer:
The correct answer is indirect value.
Explanation:
An illustration of the environmental service value is the production of a huge concentration of nitrogen within a locality. All the non-consumable values like economic values, social, cultural, aesthetic values, etc. come under the category of indirect values.
An indirect value indirectly helps an organism to thrive within a surrounding, like in the given case production of nitrogen is a non-consumable value, thus, it can also be considered as an indirect value. On the other hand, all the productive and consumable values in the form of medicine, food, etc come under the category of direct value.
