What are the principles of ecosystem sustainability?

The three principles, or pillars, of the sustainability of life on this planet are 1) solar energy , 2) biodiversity , and 3) nutrient cycling . Each of these themes interacts with one another and earth’s systems to sustain life.

What are the principles of ecosystem sustainability discuss two of them in detail?

For sustainability, ecosystems use sunlight a non-depleteable non-polluting form of energy. For sustainability, ecosystems break down and recycle all wastes as nutrients. For sustainability, Herbivore populations must be kept in check so that overgrazing and destruction of the ecosystem does not occur.

What is the basic principle of conservation?

Conservation is the process of managing change so as to best sustain its heritage values. If understanding of the past is increased, or particular heritage values are revealed or reinforced, then intervention may be justified. It is important though that any resulting harm is decisively outweighed by the benefits.

Biodiversity occurs in three different levels: Genetic, Species, and Ecosystem. Genetic diversity refers to the differences within members of a species and their ability to adapt to changes. Species diversity refers to the total number of plant, animal, and insect species that can be found in a particular region.
