What factors contributed to the diverse plant and animal life in the Amazon River basin?

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.

What factors contribute to the diversity of plant and animal life in a tropical rainforest?

Habitat suitability, i.e., vegetation structure, species composition, species richness, canopy layers, and food productivity are key drivers, which predominantly influence fauna community parameters such as species composition, relative abundance, species richness, species diversity, and the density of tropical …

What two factors lead to high animal diversity in the rainforest?

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 is the Amazon River so diverse?

Scientists agree that the rich biodiversity springs from the convulsive geological changes that the western Amazon has experienced—mountains rising, coasts shifting, rivers changing course. By fragmenting and transforming habitats, these landscape changes would have driven bursts of speciation.

What kind of plants live in the rainforest?

Ferns, lichens, mosses, orchids, and bromeliads are all epiphytes. The tropical rainforest is also home to nepenthes or pitcher plants. These are plants that grow in the soil. They have leaves that form a cup where moisture gathers.

Why is Amazon important to Earth?

The Amazon helps keep the atmosphere’s carbon-dioxide levels in check. Plants and trees take in carbon dioxide and release oxygen back into the air through the process of photosynthesis. … Fires aside, deforestation in the Amazon already releases half a billion tons of carbon dioxide each year, according to WWF.

Why is there a plenty of life forms in rainforest?

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.

What are the 4 layers of the tropical rainforest?

Most rainforests are structured in four layers: emergent, canopy, understory, and forest floor.

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.
