in ecology what term is used to describe the wise management of natural resources
Ecosystem management The term natural resource management is frequently used when dealing with a particular resource for human use rather than managing the whole ecosystem.[28] A main objective of natural resources management is the sustainability for future generations, which appoints ecosystem managers to balance natural resources exploitation and conservation over long-term timeframe.[29] The balanced relationship of each resource in an ecosystem is subject to change at different spatial and temporal scales.[30] Dimensions such as, watersheds, soils, flora and fauna, need to be considered individually and on a landscape level. A variety of natural resources are utilized for food, medicine, energy and shelter.[31]
Biomass (ecology) When energy is transferred from one trophic level to the next, typically only ten percent is used to build new biomass. The remaining ninety percent goes to metabolic processes or is dissipated as heat. This energy loss means that productivity pyramids are never inverted, and generally limits food chains to about six levels. However, in oceans, biomass pyramids can be wholly or partially inverted, with more biomass at higher levels.
