Why do unstable and extreme marine environments tend to have low biodiversity?
In general, environments that are unstable or extreme tend to have a low biodiversity. Sand, for example, easily dries out and is easily eroded by wind and water currents. Some organisms are able to survive by burrowing into sand. … Niche can be defined as the role of an organism in an ecosystem.
What is an example of an extreme marine environment?
The most studied extreme oceanic environments are the vent ecosystems, such as the hot deep-sea hydrothermal vents (DSHVs) or cold seeps and mud volcanoes, and the hypersaline ecosystems such as the deep anoxic hypersaline lakes, brine lakes on mud volcanoes, and brines contained within sea ice.
Why do habitats with high biodiversity have narrow niches?
High biodiversity means that many different species live within one habitat. Areas of high biodiversity tend to have narrow niches because it niches overlap, individuals will die out. For example, coral reefs they have high biodiversity and include many different species in a narrow niche.
Which component of biodiversity takes into account the number of different habitats and niches present in an ecosystem?
Ecological diversity includes the variation in both terrestrial and aquatic ecosystems. Ecological diversity can also take into account the variation in the complexity of a biological community, including the number of different niches, the number of trophic levels and other ecological processes.
How does species diversity increase the stability of an ecosystem?
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.
Why would it be an advantage for an organism living in a relatively stable environment to have specific habitat or food requirements?
Why would it be an advantage for an organism living in a relatively stable environment to have specific habitat or food requirements? If an organism lives in a stable environment, it may be advantageous to specialize to take advantage of specific conditions more efficiently than other organisms that do not specialize.
How do Chemotrophic bacteria Stabilise their environment in deep-sea trenches?
Deep-sea vents support productive ecosystems driven primarily by chemoautotrophs. Chemoautotrophs are organisms that are able to fix inorganic carbon using a chemical energy obtained through the oxidation of reduced compounds.
Why are extremophiles important to deep-sea ecosystems?
Extremophile microorganisms are found in several extreme marine environments, such as hydrothermal vents, hot springs, salty lakes and deep-sea floors. The ability of these microorganisms to support extremes of temperature, salinity and pressure demonstrates their great potential for biotechnological processes.
What are the two types of extreme environments on Earth?
- Polar regions.
Predator–prey interaction is inherently spatial because animals move through landscapes to search for and consume food resources and to avoid being consumed by other species.
How does a decrease in biodiversity impact an ecosystem?
Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Why ecosystem diversity is most significant for sustaining of biodiversity?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. … A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
Which one of the following ecosystem is having low diversity?
Example of ecosystem with low biodiversity is definitely a desert. Then there are cold deserts in Antarctica and Gobi basin of central Asia, where biodiversity is minimum.
