South Africa. One of the most diverse countries in the world. It contains nearly 10% of all known species of birds, fish and plants registered in the world and 6% of mammal and reptile species.
What factors support biodiversity?
1. Biodiversity & Distribution of Life
- Biotic, abiotic and human influences are all factors that affect biodiversity in an ecosystem.
- Grazing and predation are biotic factors; pH and temperature are abiotic factors.
- Biomes are the various regions of our planet as distinguished by their similar climate, fauna and flora.
What part of the earth has the most biodiversity Why?
Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Which is the planet which supports a diversity of life?
It is the combination of life forms and their interactions with each other and with the rest of the environment that has made Earth a uniquely habitable place for humans. Biodiversity provides a large number of goods and services that sustain our lives.
What 3 things make up most of the biodiversity on Earth?
Three components of biodiversity are ecosystem, species and genetic diversity.
What are the 10 limiting factor?
Limiting factors can also be split into further categories. Physical factors or abiotic factors include temperature, water availability, oxygen, salinity, light, food and nutrients; biological factors or biotic factors, involve interactions between organisms such as predation, competition, parasitism and herbivory.
What are the 5 factors that affect biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
Where do we find greatest biodiversity on Earth?
Amazonia represents the quintessence of biodiversity – the richest ecosystem on earth. Yet a study by Smithsonian scientists, published this week in the journal Science, shows that differences in species composition of tropical forests are greater over distance in Panama than in Amazonia.
Where do you find most of the biodiversity on the earth?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savanna-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
Where on earth is biodiversity at its lowest?
The arctic regions of the world have the least biodiversity because plants don’t survive in the extreme cold and ice that cover these regions year-round. However, life does exist in the arctic regions, mostly affiliated with the seas that surround them.
What is diversity of life on Earth?
Biological diversity, or biodiversity, refers to all of the variety of life that exists on Earth. Biodiversity can be described and measured at three different levels: species, genetic, and ecosystem diversity. Species diversity refers to the number of different species in an ecosystem or on Earth as a whole.
How does species support life on Earth?
Biodiversity is important because it creates a life support system for Earth. Some species create oxygen; others clean air and water, pollinate plants, manage waste, and/or provide other ecosystem services.
How does biodiversity help sustain life on Earth?
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. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
