Ecosystems that host the most biodiversity tend to have ideal environmental conditions for plant growth, like the warm and wet climate of tropical regions. Ecosystems can also contain species too small to see with the naked eye.
What ecosystem is most rich?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Which of the following ecosystem has the greatest biodiversity?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
What is richness in biodiversity?
Traditional attempts to define biodiversity consider two components: richness—the number of species in the ecosystem—and evenness—the extent to which species are evenly distributed.
What is rich ecosystem?
Some examples of ecosystems that are rich in diversity are: … Large marine ecosystems. Marine ecosystems. Old-growth forests. Rainforests.
What is an example of species richness?
Species richness is the number of species within a community or area. For example, if we have two plots of lands, A and B, and plot A has twenty four species of plants and plot B has eighty four species of plants, plot B has higher species richness.
Which region is more rich in species?
Tropical rainforests are the richest habitat of all, tropical grasslands exhibit more diversity than temperate grasslands, and deserts in tropical or subtropical regions are populated by a wider range of species than are temperate deserts.
Why is biodiversity valuable?
Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
Are biodiversity and species richness the same?
Biodiversity refers to the variety of life found in a place on the earth while species richness refers to the number of different species present in an ecological community, landscape or region. So, this is the key difference between biodiversity and species richness.
What is biodiversity types of biodiversity?
Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
Why is high biodiversity advantageous over low biodiversity?
Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.
