The Philippines is one of 18 mega-biodiverse countries of the world, containing two-thirds of the earth’s biodiversity and between 70% and 80% of the world’s plant and animal species. The Philippines ranks fifth in the number of plant species and maintains 5% of the world’s flora.
How biodiversity is rich in the Philippines?
The Philippines is one of the 17 mega biodiverse countries, containing two-thirds of the Earth’s biodiversity and 70 percent of world’s plants and animal species due to its geographical isolation, diverse habitats and high rates of endemism. The Philippines’ biodiversity provides several ecosystem services.
What is rich biodiversity?
Countries with more biodiversity in the world
America is the continent that has the most countries rich in biodiversity: Brazil, Colombia, Ecuador, Mexico, Peru, Venezuela and the United States. For its part, in Asia, the countries with the greatest bio-diversity are China, Indonesia, India, Philippines and Malaysia.
Why is it Philippines is biodiversity hotspot in the world?
Philippines: A Biodiversity Hotspot
It is considered to be a mega – diversity country because of the exceptional diversity in ecosystems, species and genetic resources found within its 7,100 island territory. … The overexploitation of natural resources, reduced the forests to an alarming 24% from its original cover.
Why biodiversity species richness is so important?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. … Greater species diversity ensures natural sustainability for all life forms.
What describes a place that has rich biodiversity it has?
Areas with extremely high levels of biodiversity are called hotspots. Endemic species—species that are only found in one particular location—are also found in hotspots.
What kind of ecosystem is the richest and most diverse in the Philippines?
Coral Reef Ecosystem
Owning 5% of the world’s total 617,000 sq km of coral reefs, the Philippines is part of the world’s “Coral Triangle,” joining Indonesia, Malaysia, Papua New Guinea, the Solomon Islands, and Timor-Leste as countries that bear the most extensive coral reef ecosystems in the world.
How can people maintain the rich biodiversity in nature?
Biological diversity can be preserved by avoiding the indiscriminate use of chemical fertilizers and pesticides in agriculture, by eradicating invasive exotic weeds, and by promoting the plantation of native trees.
What are the values of biodiversity describe each value?
The social value of biodiversity includes aesthetic, recreational, cultural and spiritual values. To this can be added health benefits resulting from recreational and other activities.
Which one is the richest area of biodiversity *?
Summary: 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.
Why the Philippine biodiversity is endangered?
The continuing habitat degradation and forestland conversion are major threats to Philippine biodiversity. These are attributed primarily to large-scale and indiscriminate logging and mining, burgeoning human population, overharvesting of resources, and infrastructure development.
Why do we need to preserve Philippine biodiversity?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. … Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.
What are the biodiversity issues in the Philippines?
Because of the isolation of some of the islands of the Philippines since the Pleistocene era, Philippine forests are home to numerous endemic life forms. Rapid deforestation, transformation of mangrove swamps, and destruction of coral reefs all point to significant loss of biodiversity.
How does species richness affect biodiversity?
Species richness refers to the number of species in an area. … The relative abundance of each species is more evenly distributed than Community 1. While both communities have the same species richness, Community 1 would have greater diversity due to the relative abundance of each species present.
What is the advantage to having high species richness in an environment?
The huge amount of work on the effects of species richness on ecosystem function have generally shown that with greater plant species richness, you tend to have increased primary productivity, nutrient uptake and greater stability to disturbances.
How does species richness affect the ecosystem?
Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.
