The bison's large influence as a grazer, a major converter of plant to animal biomass, and a key link in nutrient recycling have been lost.

Bacteria play an important role in system metabolism through nutrient recycling, which is discussed in the Trophic Relationships section.

Many concealer moths feed on dead plant material and play a useful part in nutrient recycling.

This essentially allows the space farm to turn the spaceship into an artificial ecosystem with a hydrological cycle and nutrient recycling.

Stoichiometric homeostasis helps explain nutrient recycling and population dynamics.

The researchers found that the extinction of the rarest species had little effect on nutrient recycling, as might be expected.

The extinction of the most-fished species, however, had greater effects, causing the fastest declines in nutrient recycling.

If the challenge is about future soil fertility and human health, we can develop a system based on nutrient recycling.

Like crustaceans, rotifers contribute to nutrient recycling.

By burying and consuming dung, they improve nutrient recycling and soil structure.
