Bio-capacity

• The capacity of ecosystems to produce useful biological materials and to absorb waste materials generated by human’s, using current management schemes and extraction technologies.
• The capacity of a given territory reflects its specific natural potential in terms of available resources under given management skills. It is Expressed in ha per capaita.

Carrying capacity:

• Carrying capacity of a biological species in a given environment is the maximum population
• size of this species that the environment can sustain indefinitely, given the food, habitat, water and other necessities available.
• If the population size of the species is over its carrying capacity, the environment will be degraded more or less quickly and consequently will not sustain the population which in turn will decrease.
• Moreover, if the environment itself has its resources decreasing in reason of an abiotic causes, the carrying capacity will decrease.

Ecosystem

• A system formed by the interaction of a community of organisms with their physical environment is call ecosystem.
• Species diversity: the total number of species in a area; also, the proportional distribution of species in a given area.
• Functional diversity: the number of functional roles represented in an ecosystem
