Mineral nutrients cycle through this marine food chain, from bacteria and phytoplankton to flagellates and zooplankton which are then eaten by fish.
42.
Natural forests help conserve biodiversity which in turn maintains ecosystem productivity, nutrient cycling, ecosystem resilience to disturbance, and resistance to insect damage.
43.
However, like most ecosystem processes, nutrient cycling is not an ecosystem characteristic which can be dialed to the most desirable level.
44.
This allows xylophages to develop and in turn affect dead wood, contributing to wood decomposition and nutrient cycling in the forest floor.
45.
Once these colonies are decimated by introduced predators, the nutrient cycling is interrupted and the plant communities on the islands change drastically.
46.
This has led not only to the loss of wildlife habitat, but also other forest services, such as carbon sequestration and nutrient cycling.
47.
Salamanders and other amphibians contribute greatly to nutrient cycling through their consumption of small life forms on the forest floor and in aquatic habitats.
48.
The warming trend is reducing the frequency of deep mixing in the lake, and may have important effects on water clarity and nutrient cycling.
49.
Nutrient cycling occurs in ecosystems that participate in the " larger biogeochemical cycles of the earth through a system of inputs and outputs ."
50.
These areas contribute a great abundance of population ( not species ) level biodiversity and ecosystem services, including cultural value and planetary nutrient cycling.
