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.

Are rainforests the most productive ecosystem?

Tropical Rainforest Ecosystems

According to the World Wildlife Fund, “Tropical forests are some of the richest, most exciting areas on earth. … Fungi, bacteria and other microorganisms all play a key role in supporting one of the world’s most productive ecosystems.

Why are rainforests the most productive?

Tropical Rainforests support the greatest number of species compared to any other biome on the planet. The high species diversity is brought about by warm temperatures and year-round rainfall – the average yearly rainfall is 100 inches – that ultimately allow for optimal growth.

Why is the rainforest considered a complex ecosystem?

The tropical rain forest is the most complex ecosystem in the world. Large number plants and animals are found in the tropical rain forest. … As plants capture lots of energy from sunlight, survival of large number of complex and different types of organisms could be possible.

Which tropical ecosystem is the most productive and most diverse ecosystem on Earth?

Today we will examine the most productive and diverse ecosystem found on land: the tropical rain forest. These ecosystems are also, and perhaps more accurately, called humid tropical forests.

What is the most productive ecosystem on earth?

Wetlands and Nature

  • Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. …
  • Wetlands play an integral role in the ecology of the watershed. …
  • Wetlands’ microbes, plants and wildlife are part of global cycles for water, nitrogen and sulfur.

Which part of ecosystem is the most productive?

The world’s ecosystems vary tremendously in productivity, as illustrated in the following figures. In terms of NPP per unit area, the most productive systems are estuaries, swamps and marshes, tropical rain forests, and temperate rain forests (see Figure 4).

What does it mean that an ecosystem is most productive?

The primary productivity of an ecosystem is defined as the speed at which the solar energy is turned into an organic substance by chlorophyll in the photosynthesis.

What makes a highly productive ecosystem?

‘Productive’ ecosystems are defined as those that support a large total amount of living matter, from tiny microbes up to plants and animals. … Conversely, when there is too much dispersal in an ecosystem, species evolve to be ‘generalists’ that can survive in many habitats, but fail to thrive in any given one.

Why are tropical wet forests and estuaries most productive?

Tropical Rainforests have high primary productivity because of availability of plenty of solar light and water. A typical estuary has high primary productivity because it is shallow (gets plenty of sunlight) and has turbulent water (which brings the nutrient rich material from sea bed).

What is a rainforest ecosystem?

A rain forest is simply an area of tall, mostly evergreen trees and a high amount of rainfall. … A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall. Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years.

Why do tropical rainforests have high biomass?

Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. … Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.

Why is rainforest known as the lungs of the earth?

Tropical rainforests are often called the “lungs of the planet” because they generally draw in carbon dioxide and breathe out oxygen. … Carbon dioxide increases each year as a result of burning fossil fuels and deforestation.

What is the most productive ecosystem in the ocean?

Coral reefs are among the most productive ecosystems on the planet, with the primary producers at the base of the food chain (including corals) supporting their complex food webs.

Which of the following is least productive ecosystem?
