What are key concepts of ESS?

09 May What are key concepts of ESS?

The key concepts of ESS depend on each individual ESS topic. Some of the most important concepts of ESS are:

• Ecological footprint –  measures the amount of “biologically productive” land or water that enables the population to sustain itself.
• Carrying capacity –  is the maximum population that a given area can sustain.
• EVS –  might be considered as a system in the sense that it may be influenced by education, experience, culture and media (inputs), and involves a set of interrelated premises, values and arguments that can generate consistent decisions and evaluations (outputs).
• Parasitism – The host provides a habitat and food for the bacteria, but in return, the bacteria cause disease in the host. This is an example of parasitism or an association between two different species where the symbiont benefits and the host is harmed.
• Density – independent factors – Factors that affect a population irrespective of population density notably environmental change.  Abiotic factors are density-independent factors, the most important ones are the extremes of weather.
• Species diversity– is defined as the number of species and abundance of each species that live in a particular location. The number of species that live in a certain location is called species richness.
• Soil system storages – include organic matter, organisms, nutrients, minerals, air and water.
