b. Policies involving resource use determine the level of monitoring required for the environment.
c. Resource use is independent of the environment, so monitoring environmental parameters is an ineffective practice.
d. Environmental parameters indicate whether or not resource use is harming the environment.
b. biotic
Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
The term biotic factors has been defined as living factors present in the ecosystem. Biome is a separate biogeographical region that contains its own living and non-living factors along with a characteristic climate. The examples of biomes are: Tundra, Temperate, Desert, etc.
Changing a biotic or abiotic factor can affect each other or even the entire biome because these factor live in a state of dynamic equilibrium by being interdependent on each other. Therefore, if this equilibrium is disturbed then the survival of some living organism may be disturbed that can eventually lead to ecological succession.
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community.
Therefore, Organisms within an ecosystem are biotic factors in that ecosystem. Thus, option B is correct.
