Which region has the largest variety of plants and animals?

Which region has the largest variety of plants and animals?

Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of all plants and animals found on land.

What portion of known plants and animals live in rain forests?

In fact, though rainforests cover less than 2 percent of Earth’s total surface area, they are home to 50 percent of Earth’s plants and animals, according to The Nature Conservancy.

Which layer has the most plant and animal life?

The canopy, which may be over 100 feet (30 m) above the ground, is made up of the overlapping branches and leaves of rainforest trees. Scientists estimate that 60-90 percent of life in the rainforest is found in the trees, making this the richest habitat for plant and animal life.

Which rainforest is home to the greatest variety of plants and animals on Earth?

The Amazon jungle
The Amazon jungle is the world’s largest tropical rainforest. The forest covers the basin of the Amazon, the world’s second longest river. The Amazon is home to the greatest variety of plants and animals on Earth.

Why do tropical rain forests contain a large variety of plants and animals?

Tropical rain forests are warm and wet, and the temperature does not vary much. Because of this, a huge variety of plants can live in tropical rain forests. Because there are so many kinds of plants, there are habitats for many different kinds of animals as well.

How many living species and counting are known?

The natural world contains about 8.7 million species, according to a new estimate described by scientists as the most accurate ever. But the vast majority have not been identified – and cataloguing them all could take more than 1,000 years.

Why is it called the emergent layer?

The top layer of a rain forest is called the emergent layer. This layer receives bright sunlight and plenty of rain, and is also very windy. The tallest trees rise above every other plant to a height of 230ft (70m). Animals in this layer, such as monkeys, are agile, with a good sense of balance.

Why do different plants and animals live in different layers of the rainforest?

Rain forests are divided into four layers, or stories: emergent layer, canopy, understory, and forest floor. Each layer receives a different amount of sunlight and rainfall, so different types of animals and plants are found in each layer.

How does the rainforest climate affect the animals and plants?

Degraded forests and food shortages result in an increased number of threatened species. Tropical rainforests are home to nearly 30 million species of plants and animals, which heavily rely on another for survival. As plant growth dwindles, these animals become vulnerable.

Why do tropical rainforests have high rainfall?

Since tropical rainforests have so many plants, there’s a ton of transpiration. When you get that much water vapor hovering over rainforests, it’s bound to rain a lot. In sum, tropical rainforests only exist in areas of high rainfall, but they also cause more precipitation through transpiration.

Which of the following is a characteristic of tropical rain forests quizlet?

forest biomes- tropical rainforests are forests or jungles near the equator. They are characterized by large amounts of rain and little variation in temperature and contain the greatest known diversity of organisms on earch.

What kind of animals live in humid subtropical climate?

Humid Subtropical supports many types of mammals, reptiles, and amphibians. Alligators, deer, and panthers can be found in the US. Brazil’s subtropical area has the capybara, which is the worlds largest rodent.

What kind of plants grow in humid subtropical climates?

The natural vegetation found in Humid Subtropical areas are mainly evergreen trees, bushes, and shrubs. These are not the hardy evergreen trees like pine and spruce. Most of these evergreens are more delicate. The reason many plants here are evergreens is because of the long months of warmth and regular rain.

What kind of plants are found in tropical rainforest?

Some unique species of plants that are found in tropical rainforests are orchids, epiphytes, amazon water lily, silky oak, bromeliads, and so on.

What is the most interesting thing about the rainforest?

The most interesting thing about rainforest flora is that the roots do not grow in the soil, but are aerial plants, and the water they drink to live properly comes from rainfall. Thanks to these plants, there are many insects that also feed on them. Flowers and fruits are a source of food for other animals.
