The diversity of species and genes in ecological communities affects the functioning of these communities. … More biologically diverse communities appear to be more productive (in terms of biomass production) than are less diverse communities, and they appear to be more stable in the face of perturbations.
What are effects of biodiversity?
Even though only a minority of humans realize it, biodiversity provides humans with food, water, oxygen, energy, detoxification of waste, stabilization of earth’s climate, medicine, opportunities for recreation and tourism, and many more things (Secretariat, 2000).
What is the effect of biodiversity on ecosystem productivity?
According to the insurance hypothesis, biodiversity insures ecosystems against declines in their functioning because many species provide greater guarantees that some will maintain functioning even if others fail.
What are the negative effects of biodiversity?
destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
How does biodiversity affect the economy?
Biodiversity Underpins Economic Activity
Agriculture, forestry and fisheries products, stable natural hydrological cycles, fertile soils, a balanced climate and numerous other vital ecosystem services depend upon the conservation of biological diversity.
Why does the biodiversity of an ecosystem affect its resilience?
Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.
What is the effect of biodiversity on ecosystem productivity quizlet?
What is the effect of biodiversity on ecosystem productivity? Increased biodiversity increases productivity.
How does high biodiversity affect an ecosystem apex?
Biodiversity increases ecosystem stability. That is, an ecosystem with high biodiversity is more likely to be stable than an ecosystem with low…
How can biodiversity have a negative effect on the sustainability of an ecosystem?
While biodiversity has often been used as a synonym for species richness (the number of species present), different components of biodiversity (e.g., richness, relative abundance, composition, presence/ absence of key species) can have different effects on ecosystem properties.
What are the causes and effects of biodiversity loss?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming. In each case, human beings and their activities play direct roles.
