The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round.
Where is biodiversity the greatest least?
Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.
Which one system has lowest biodiversity?
The tundra is the biome with the least biodiversity.
Which ocean zone has the most biodiversity?
The epipelagic zone stretches from the surface down to 200 m and is home to the greatest biodiversity in the sea, largely because of the availability of sunlight that enables photosynthetic organisms to thrive. Both marine plants and animals are found here.
Which continent has the most biodiversity?
America is the continent that has the most countries rich in biodiversity: Brazil, Colombia, Ecuador, Mexico, Peru, Venezuela and the United States.
Which region has greatest diversity?
Author’s note: The data that underpins this post is updated on a regular basis on Mongabay’s rainforest site: Amphibians, Birds, Fish, Mammals, Reptiles, Vascular Plants.
What is an example of an area with low biodiversity?
Low biodiversity is characteristic of an unhealthy or degraded environment. A mown lawn in a city park is an example of an ecosystem with low biodiversity. There will be two or three kinds of grasses, some dandelions, of course, and maybe a robin or some starlings poking about for worms or bugs.
Which regions have high levels of biodiversity?
Some areas in the world, such as areas of Mexico, South Africa, Brazil, the southwestern United States, and Madagascar, have more biodiversity than others. Areas with extremely high levels of biodiversity are called hotspots.
How can you tell if an ecosystem has low biodiversity?
Biodiversity is the number of species found within a habitat or an ecosystem. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat.
Which of the following regions of the ocean is least likely to contain photosynthetic organisms?
Thus the least likely of these zones to contain photosynthetic organisms is the abyssal zone, the part of the ocean deeper than about 2,000 m and the deepest of this group.
Which ocean has the least fish?
The Arctic Ocean is the smallest of the world’s five major oceans and the shallowest.
What does the abyssal zone look like?
The conditions of the Abyssal Zone are almost constant. It is dark and cold at all times (averaging 2 degrees Celcius at 4000 meters). It is calm and unaffected by sunlight and turbulent seas, far above.
