Six thousand reindeer once lived on a remote island in the Bering Sea
that was briefly their paradise. In what has become a classic story of
wildlife boom and bust, no reindeer live on St. Matthew Island now.
Three scientists just looked back at the St. Matthew's reindeer herd and
found that an extreme winter probably pushed the stressed animals to
their deaths.
Answer:
There is a positive relationship between environmental policies and jobs and the economy.
Explanation:
The conclusion of the studies is that environmental policies increase employment in the industrial sector. It is because for reducing pollution, the industries does not use heavy machinery for increasing production so these industries uses labour to maintain its production capacity and for more production more labour is required which decrease the problem of unemployment while economy also increases due to more production of products in the industries.
The control group is the part of an experiment that does not receive the variable and is used for comparison.
The huckleberry patches will provide a very high level of consumption efficiency.
<h3>What is consumption efficiency?</h3>
Consumption efficiency refers to the ability of a consumer to be able to derive the maximum level of consumption from a given resource or group of resources.
The huckleberries depend on the animals such as Bears as well as other herbivores for seed dispersal and propagation. These plants have therefore, develop efficient means to encourage dispersal by these animals. The seeds of the Huckleberries are enveloped in sweet, nutritious fruit that is comparatively undefended.
Therefore, the Bears and other herbivores will derive a very high level of consumption efficiency from the Huckleberry patches.
In conclusion, consumption efficiency measures the ability of a consumer to derive maximum consumption. High consumption efficiency implies that the resource provides a great deal of benefit and satisfaction to the consumer.
