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 are the most biologically diverse ecosystems?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than 25% of all marine life.
What are the two types of biological diversity?
Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
Which ecosystem is the most diverse in the world?
Do you know that more than 40 percent of world’s animal and plant species live or breed in wetlands? This incredible figure makes wetlands the most biologically diverse ecosystem in the world.
Which species has most diversity?
The sponges, Poriferans, were found to have some of the greatest diversity of both body size and species, ranging from microscopic to the size of an automobile. Molluscs (snails, squid, clams, chitons), and Arthropods (crabs, insects, lobsters, copepods) also showed great diversity.
Which among the following species has most diversity?
Fungi has highest species diversity among all plant groups.
What is example of diverse ecosystem?
Grasslands, tundras, deserts, rainforests, terrestrial and marine ecosystems, are some examples of ecosystems that are diverse and contribute a lot to creating a well-balanced environment.
What is the ecosystem diversity?
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 are the three different types of ecological diversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What are the two most genetically different species?
Bacteria and viruses tend to have very high genetic diversity, Cutter said. But it’s hard to make an apples-to-apples comparison of genetic diversity between bacteria and viruses on one hand, and eukaryotes on the other, because species are defined differently in those categories, Cutter said.
Which of these has the most genetic diversity?
Genetic diversity is known to be the different subspecies of a particular cereals or fruit. Complete answer: Rice has the most subspecies and genetic diversity among all the options. Rice has almost fifty thousand subspecies in India which makes it the most diverse in genetics.
Where is the world’s largest biological diversity found?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
