Why is biodiversity important in the desert ecosystem?

Biodiversity includes all organisms, species, and populations. Due to harsh climate in deserts, only some of the most unusual plants and animals can survive in such regions. … The great wealth of plant and animal life in desert areas are also an important source of local livelihoods.

How does biodiversity affect the desert?

However, biodiversity increases close to desert water sources such as seasonal rivers and lakes and near to an oasis. The dry conditions are suitable for xerophytes, plants that are able to survive through adaptations such as thick, waxy cuticles and the loss of leaves to reduce water loss through transpiration.

What is the biodiversity in the desert?

The biodiversity, or variety of life in the desert, is based upon organisms that are specially adapted to survive without a ready supply of water. Whether hot or cold, the biodiversity of the desert is very low. In a hot desert environment, plants consist primarily of cacti.

Why is the desert ecosystem important?

The Desert Biome is an important part of Earth because many animals live in it and it is a source of sand. Also, a lot of oil is often found under many deserts. The Desert Biome is home to insects and spiders that frogs and birds eat. … The Desert Biome is also important because it has its own ecosystem.

Why is biodiversity low in deserts?

There is very little biodiversity in hot deserts because of the harsh climate. Few species are specialised enough to survive there. Plants and animals which do survive there have adapted to difficult conditions.

Why is biodiversity important?

Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Why biodiversity is lower in a desert ecosystem than in a tropical rainforest?

The biodiversity of these two biomes is vastly different. Both biomes have warm climates, but the desert is very dry, and the rainforest is very wet. The desert has very few organisms, so it has low biodiversity. … In contrast, the rainforest has the highest biodiversity of any biome on Earth.

How does biodiversity and sustainability work together?

The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable. Lower/less biodiversity = less sustainable. … The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem.

What is the biodiversity like in the Sahara Desert?

Biodiversity Features

The flora of the central Sahara Desert is very poor and estimated to include only 500 species (Le Houérou 1990). This is extremely low considering the huge extent of the area. It mainly consists of xerophytes and ephemeral plants (called also locally Acheb), with halophytes in moister areas.

What are the main threats to biodiversity in hot deserts?

Increasing evaporation and dust storms are pushing deserts out into communities at their edges. This desertification is exacerbated by human exploitation of ecosystems that border deserts, causing land degradation, soil erosion and sterility, and a loss of biodiversity.

What would happen if there were no deserts?

If there were no deserts, all of the life (plants and animals) that are adapted to a desert environment would either 1) die, or 2) adapt to a different environment in order to survive. Answer 3: Deserts form because of the location of mountains and because of the way air circulates around the planet.

What factors in the environment affect the biodiversity of organisms in an area?

Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
