Why are tropical forests so productive?
What makes humid tropical forests so productive is the combination of high temperatures, light, and rainfall year-round (good growing conditions), coupled with especially efficient nutrient recycling.
Why are tropical rainforests so important for biodiversity?
Rainforests contain about half of the existing plant and animal species in the world. They contain a third of the world's bird species and 90% of its invertebrates. The remaining African rainforests contain more animals and plant species than are found anywhere else on the continent.
Are tropical rainforests highly productive?
Tropical forests are among the most productive ecosystems on the Earth, estimated to account for about one-third of global net primary productivity (NPP) (1,2), but have been relatively under-sampled compared with their importance. The NPP of an ecosystem is one of the fundamental parameters describing its functioning.
How biodiverse are tropical rainforests?
As an ecosystem, the Amazon is one of the most biodiverse places on earth. Over 3 million species live in the rainforest, and over 2,500 tree species (or one-third of all tropical trees that exist on earth) help to create and sustain this vibrant ecosystem. More and more, biodiversity is at risk.
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).
Why are the tropical areas richer in biological resources than polar areas?
– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.
Why is there high biodiversity in the tropics?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
Why is the tropical rainforest the most diverse biome?
Explanation: The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.
What is the most productive ecosystem?
Tropical rainforests Tropical rainforests show the highest productivity in terrestrial ecosystems.
Which of the following are features that contribute to the high productivity of tropical rainforests?
The tropical rainforest biome has four main characteristics: very high annual rainfall, high average temperatures, nutrient-poor soil, and high levels of biodiversity (species richness). Rainfall: The word “rainforest” implies that these are the some of the world's wettest ecosystems.
Why do forests have a high biodiversity?
Forests have high biodiversity because the vertical growing surface and resulting canopy shade creates micro-niches by altering locally available light, heat & moisture.
Which is the most productive ecosystem?
Tropical rainforests Tropical rainforests show the highest productivity in terrestrial ecosystems.
Which biome has the highest productivity Why?
Tropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes. Net primary productivity ranges from 2–3 kg m-2 y-1 or higher.
Why are the tropics so biodiverse?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
Why is biodiversity so rich in tropics?
– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.
Why is there so much biodiversity?
The Earth's biodiversity is the result of 4 billion years of evolution — change in the inherited traits of a population of organisms from one generation to the next. Up until about 600 million years ago, life consisted of single-celled organisms.
Why tropical rainforest is acknowledged as one of the most diverse ecosystems on Earth?
Tropical rainforests have the highest mean net primary production of any terrestrial ecosystem, meaning an acre of rainforest stores more carbon than an acre of any other vegetation type. The humid climate adds another ingredient essential to rich diversity: water.
Which causes the biodiversity of rainforests?
SOLAR ENERGY/CLIMATE The hot and humid climate plays an important role in rainforest variety. As a general rule, diversity and ecosystem productivity increase with the amount of solar energy available to the system.
What are the most productive ecosystem and why?
In an ecosystem, primary productivity refers to the accumulation of energy in terms of biomass. In aquatic ecosystems, coral reefs have the highest productivity. Tropical rainforests show the highest productivity in terrestrial ecosystems.
Which forest is most productive?
tropical rain forests Thus, tropical rain forests are the most productive ecosystem.
Why is the tropical climate good for biodiversity?
The higher temperatures in the tropics cause higher rates of metabolism, ecological dynamics and coevolutionary processes, which generate and maintain higher biodiversity.
Why is the tropical rainforest the most diverse terrestrial biome?
Explanation: The high species richness or biodiversity found in tropical rain forests is mainly due to their geographic location and the amount of precipitation they receive. Tropical rainforests fall along the equator and receive a large amount of precipitation.
Why are the tropics so rich in biodiversity?
– Tropical latitudes produce more solar power than temperate zones, resulting in high productivity and high diversity of biodiversity. – There are fewer seasonal changes in tropical regions and they have a more or less stable climate. This encourages the specialization of the niche and hence the high wealth of animals.
What factors make the biodiversity so high?
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.
Which ecosystem shows more productivity than tropical forests and why?
More solar energy and resources are available in tropics which promotes higher productivity. On land the maximum primary production rate is found in tropical rainforests followed by tropical deciduous forests, temperate forests, savannah, temperate grasslands and desert scrub….

Why are tropical wet forest 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).
Why is tropical forest most diverse?
The findings confirm a prediction from the 1970s, which posited that tropical forests are diverse because natural enemies keep populations in check. An enemy could be a seed eater, an herbivore or a pathogen, said Kellner, who is affiliated with the Institute at Brown for Environment and Society.
Why are tropics the most diverse areas?
There are more species in the tropics because tropical ecosystems have more niches. However, the number of niches in an ecosystem is determined by the number of species in that ecosystem.
What is the most productive ecosystem in the biosphere?
Thus, tropical rain forests are the most productive ecosystem.
What makes an ecosystem highly productive?
A high primary productivity rate in the ecosystems is obtained when the physical factors (for instance: water, nutrients and climate) are favourable. The presence of some forms of secondary energy can also help to increase the primary productivity rate.
