At a global scale, each group of living organisms may reach its greatest species richness in a different part of the world because of historical circumstances or the suitability of the site to its needs. Larger areas also can provide a greater range of habitats in which species can evolve and live.
Why are ecosystems so diverse?
Ecological diversity around the world can be directly linked to the evolutionary and selective pressures that constrain the diversity outcome of the ecosystems within different niches. Tundras, Rainforests, coral reefs and deciduous forests all are formed as a result of evolutionary pressures.
What factors contribute to more diverse ecosystems?
Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species,6 but also contributes to the diversity of food, fiber, and medicines available from nature.
What is diversity of ecosystem?
Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.
What is the most diverse ecosystem?
Forests are the most diverse ecosystems on land, because they hold the vast majority of the world’s terrestrial species. Some rain forests are among the oldest ecosystems on Earth.
What affect the diversity of an ecosystem?
Broadly speaking, the diversity of an ecosystem is dependent on the physical characteristics of the environment, the diversity of species present, and the interactions that the species have with each other and with the environment. … Also, the energy flux in the environment can significantly affect the ecosystem.
What is ecosystem What are examples of diverse ecosystem?
Answer: An ecosystem is a geographic area where the plants,animals and other organisms,as well as weather and landscape,work together to form a bubble of life. Forests,desert, grasslands and streams are the examples of diverse ecosystem.
Why is an ecosystem with high index of diversity more favorable than the one with low index of diversity?
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 is the main requirement for a diverse ecosystem?
A diverse ecosystem contains a variety of different organisms. Therefore, such an ecosystem should have enough resources in terms of food and habitat to accommodate and support the different types of organisms.
What will best describe ecosystem biodiversity?
Ecosystem biodiversity refers to the variety of ecosystems, by their nature and number, where living species interact with their environment and with each other. … Each ecosystem has its own peculiarities, species, and ways of functioning.
