Why are some habitats more biodiverse than others?
There are at least three possible scenarios or “routes” that a region may follow to become a biodiversity hotspot: a region can have lots of species because it generates species at faster rates than nearby areas, or because they import species from their surroundings at faster rates (that is, they attract species), or …
Why is a habitat with high biodiversity more stable?
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.
What habitat has the greatest biodiversity and why?
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.
What makes an ecosystem with high biodiversity?
Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
Is high biodiversity more advantageous than low biodiversity?
High biodiversity is advantageous over low biodiversity because ecosystems with high biodiversity are better able to remain at homeostasis and be…
Why do some places contain more species than others?
Species richness in a given location is the result of three factors — the rate of speciation, the rate of extinction, and the dispersal of species from other locations.
What supports high biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
How will increasing species diversity affect the ecosystem?
Explanation: By increasing species diversity in an ecosystem, both the efficiency and the productivity of an ecosystem will increase. A greater species richness and diversity may cause ecosystems to function more efficiently and productively by making more resources available for other species.
Which habitat exhibits the greatest biodiversity?
Specifically, biodiversity of land species is greatest in tropical forests and marine diversity is greatest along coral reefs.
Where is biodiversity greatest?
Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
How can an increase in biodiversity lead to an increase in ecosystem stability?
How can an increase in biodiversity lead to an increase in ecosystem stability? … An increase in the biodiversity of an ecosystem leads to an increase in its productivity. T. Ecosystems with greater biodiversity have an increased stability.
Why is there a low species diversity in the desert?
Biodiversity is low in hot desert ecosystems. There are far fewer species supported by the extreme climate compared to other biomes. This is due to the high temperatures, low rainfall and a lack of available water. … A small change in biotic or abiotic conditions can have a significant impact on the ecosystem.
Why is biodiversity important for the stability of the ecosystem?
Biodiversity boosts ecosystem productivity where each species, no matter how small, has an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all forms of life.
