Complete answer: The tropical rainforest is the most complex ecosystem in the world as it consists of a large number of plant and animal species that vary among each other.
What is a complex ecosystem?
An ecosystem is a complex system composed of organisms living in a given habitat. … Each ecosystem contains a given amount of organic matter that includes all its vegetal and animal organisms: the weight of such matter is called ‘biomass’, and is calculated dry and per surface unit occupied by the ecosystem.
Where are most ecosystem located?
Ocean ecosystems are most common on Earth, as oceans and the living organisms they contain cover 75% of the Earth’s surface. Freshwater ecosystems are the rarest, covering only 1.8% of the Earth’s surface. Terrestrial, land, ecosystems cover the remainder of Earth.
What is the most common ecosystem in the world?
Ocean ecosystems are the most common, comprising 75 percent of the Earth’s surface and consisting of three basic types: shallow ocean, deep ocean water, and deep ocean surfaces (the low depth areas of the deep oceans).
Are rainforests the most productive and most complex ecosystems on Earth?
Rainforests cover less than two percent of the Earth’s surface. They are home to some 50 to 70 percent of all life forms on our planet. Rainforests are the most productive and most complex ecosystems on Earth.
Which of the following is a most complex ecosystem in the world?
Tropical rainforest is most complex ecosystem in the world.
Which of the following is the most complex component of environment?
The biosphere is very large and complex and is divided into smaller units called ecosystems.
Which region has greatest diversity?
Species diversity is greatest in the tropics, particularly in tropical forests and coral reefs. The Amazon basin in South America has the largest area of tropical forests.
Which is the most biodiverse region in the world and why?
Brazil. This country has the greatest biodiversity of flora and fauna on the planet thanks to the presence of the Amazonia on its territory. Brazil has the highest population of species of mammals and freshwater fish. Besides, it hosts more than 50,000 species of trees and bushes.
Why is the most biodiversity found near the equator?
There might be more biodiversity near the equator because it’s warmer year round, allowing organisms to continue growing. Locations away from the equator will have cold winters that will slow growth for microorganisms, plants and animals.

Which type of ecosystem is the least common on the planet?
Freshwater ecosystems are the least common, occurring on only 1.8 percent of Earth’s surface. These systems comprise lakes, rivers, streams, and springs; they are quite diverse, and support a variety of animals, plants, fungi, protists and prokaryotes.
