Oxygen consumption of profundal tubificids at 15C in relation to starvation, i .e . A lake ecosystem or lacustrine ecosystem includes biotic (living) plants, animals and micro-organisms, as well as abiotic (non-living) physical and chemical interactions. As there is little oxygen at this level, heterotrophs use oxygen for cellular respiration. What animals live in the profundal zone? Typically, oligotrophic, or young, bodies of water have narrow Littoral Zones due to their steep sides. Lake ecosystems are a prime example of lentic ecosystems (lentic refers to stationary or relatively still freshwater, from the Latin lentus, which means "sluggish"), which include ponds, lakes and wetlands, and much of this . The profundal zone is the area of a lake or pond that extends from the waters surface to its deepest point.

This zone is mainly inhabited by primary consumers that are either attached to or crawl along the rocks at the bottom of the lake or pond such animals are called benthos. This promotes excessive growth of algae, which along with decomposing organisms deplete the water of oxygen, causing the death of other organisms.
