Readers ask: What Factor Most Affects Nutrient Cycling?


What are the factors affecting nutrient cycle?

Nutrient cycling is strongly influenced by forest disturbances shaping nutrient availability and stoichiometry (i.e., ratios of available nutrients ) immediately after disturbance and the species composition of the post-disturbance landscape.

What are the 3 main nutrient cycles in an ecosystem?

The three main cycles of an ecosystem are the water cycle, the carbon cycle and the nitrogen cycle.

What are 4 of the most important nutrients to cycle through the ecosystem?

Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist.

How are humans disrupting nutrient cycles?

However, human activity has so thoroughly disrupted Earth’s natural nutrient cycles that we have degraded soils and created aquatic dead zones. The rapid decimation of large terrestrial mammals was the first step in humanity’s disruption of nutrient cycles.

What are two factors that could disrupt the nitrogen cycle?

Inherent factors such as rainfall and temperature; and site conditions such as moisture, soil aeration (oxygen levels), and salt content (electrical conductivity/EC) affect rate of N mineralization from organic matter decomposition, nitrogen cycling, and nitrogen losses through leaching, runoff, or denitrification.

Why is the nutrient cycle important?

Nutrient cycles link living organisms with living organisms, living organisms with the non-living organisms and non-living organisms with non-living organisms. This is essential because all organisms depend on one another and is vital for the survival of living organisms.

How many nutrient cycles are there?

Mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus cycle, oxygen cycle, among others that continually recycle along with other mineral nutrients into productive ecological nutrition.

Why is nutrient cycling so important in ecosystems?

Nutrient cycles restore ecosystems to the equilibrium state, and therefore play an important role in keeping the ecosystem functioning. All organisms, living and non-living depend on one another. Nutrient cycles link living organisms with non-living organisms through the flow of nutrients.

Do nutrients cycle or flow through an ecosystem?

Energy and nutrients, or chemicals, flow through an ecosystem. While energy flows through the ecosystem and cannot be recycled, nutrients cycle within an ecosystem and are reused.

What factors can disrupt the biogeochemical cycles?

found in ecosystems containing various trophic levels.

  • Natural events or human activities can disturb Biogeochemical cycles.
  • Human activities include: Overuse of fertilizers or herbicides. – runoff affects bodies of water causing algae blooms.
  • Natural events include: Volcanic activity.

What is the role of trees in the nutrient cycle?

As trees grow and their structures are renewed, plant residues, such as branches, leaves, bark, and fruits, accumulate on the forest floor, and roots die and release organic matter into soil. These organic materials serve as an energy source for the decomposer community.

Why the cycling of nutrients depends on gravity?

The cycling of nutrients is also the source of energy, and the resource is limited. Gravity allows the planet to hold onto its atmosphere and helps to enable the movement and cycling of chemicals through air, water, soil.

Which two biogeochemical cycles are most closely tied together?

Which two biogeochemical cycles are most closely tied together? Why are they linked? The oxygen & carbon cycles.

What is nutrient cycle in ecosystems?

The nutrient cycle is a system where energy and matter are transferred between living organisms and non-living parts of the environment. This occurs as animals and plants consume nutrients found in the soil, and these nutrients are then released back into the environment via death and decomposition.

How can I increase my nutrient cycling?


  1. Reduce unintended losses.
  2. Enhance nutrient uptake efficiency.
  3. Tap local nutrient sources.
  4. Promote consumption of locally produced foods.
  5. Reduce exports of nutrients in farm products.
  6. Bring animal densities in line with the land base of the farm.
