Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. … Biologists estimate that tropical rainforests contain about 50% of the world’s terrestrial plant and animal species, yet they encompass only about 6% of the world’s land area.
What is the biodiversity of the rainforest?
Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. The Amazon rainforest is the world’s largest tropical rainforest. It is home to around 40,000 plant species, nearly 1,300 bird species, 3,000 types of fish, 427 species of mammals, and 2.5 million different insects.
How much biodiversity do rainforests have?
The Amazon Rainforest and Biodiversity
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 is the rainforest biodiversity?
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.
How does the rainforest support biodiversity?
CANOPY STRUCTURE AND BIODIVERSITY IN THE RAINFOREST
The canopy system characteristic of tropical rainforests further increases diversity by creating new niches in the form of new sources of food, new shelters, new hiding places, and new areas for interaction with other species.
How will you describe a tropical rainforest?
The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers. … They climb trees in the canopy to reach for sunlight. The middle layer, or understory, is made up of vines, smaller trees, ferns, and palms.
Why is biodiversity important to the Amazon rainforest?
Amazon biodiversity also plays a critical role as part of global systems, influencing the global carbon cycle and thus climate change, as well as hemispheric hydrological systems, serving as an important anchor for South American climate and rainfall.
Why is the biodiversity of a tropical rainforest very high quizlet?
Biodiversity is high because the warm and wet consistent climate in tropical rainforests is able to sustain life in all different forms. Soil nutrient is poor in tropical rain forests because the sunlight that is intended to reach the floor of the tropical forest is blocked by the tall and dense trees.
Why do you think tropical rainforest have high levels of biodiversity?
Rainforests have high biodiversity because they are abundant in nutrients, energy and a favorable climate.
Why does the tropical rainforest have the greatest biodiversity of any type of land ecosystem?
Tropical rain forests have the greatest biodiversity of any type of land ecosystem. … The presence of a variety of herbivore species that can feed on a large number of different producer species helps ensure abundant prey for predators in the ecosystem.
What changes have there been to biodiversity in the tropical rainforest?
Deforestation and fragmentation, over-exploitation, invasive species and climate change are the main drivers of tropical forest biodiversity loss. Most studies investigating these threats have focused on changes in species richness or species diversity.
Why haven’t Scientists named all of the species that live in tropical rainforests?
There are so many animals in tropical rainforests that we haven’t been able to name them all yet. Many of these unusual animals only live in tropical rainforests. They don’t live anywhere else on Earth. Some of these species have had to adapt to their rainforest surroundings in order to survive.
Why are tropical forests also known as stratified forests?
In tropical forests tall trees of several species have their crowns forming a superior layer under which diverse other trees and plants develop forming other inferior layers.
