If the cold and warm front collide the warmer air rises and colder air moves to the bottom due to the density of warm air is less than cold air which creates a front that is the boundary front of both fronts.
It forms a new front called an occluded front. The occluded front causes heavy precipitation, strong winds. and snow sometimes. In low pressures it also caused tornadoes.

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.
