Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water
Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.
To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.
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.

Building models doesn't actually help scientists observe phenomena. Scientists build models to describe how nature and systems operate then make observations to see if their models match what they observe. Models which don't match what they observe are either alterated or scrapped. Good models are kept and used by the scientific community.
