Answer 1

Hint: The variety of life and their variability on earth that included genetic, species and ecosystems is known as biodiversity. Biodiversity is the term popularized by sociobiologist Edward Wilson to explain the variability of life on the world at genetic, species and ecological levels.

Complete answer: Biodiversity plays an important role in the functioning ecosystem that includes the supply of oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and other ecosystems services.
Biodiversity is very important to humans for several reasons, as plants, animals and human beings are interdependent and form a complex web of the ecological system in which humans are very much dependent on this system for their own existence.
Humans depend for their livelihood such as farmers, fisher’s timber workers on biodiversity.
Humans for their survival depend on biodiversity such as we need oxygen, clean air and water.
Our tourism industries included birdwatching, hiking, camping and fishing completely depends on biodiversity.
An Australian culture is strongly connected to animals and plants and has a spiritual belief in biodiversity.
Human activities are responsible for declining the biological wealth of the planet which results in the extinction of some species. The extinction of more than 2,000 species of native birds in tropical pacific islands is a result of colonization. The loss of biodiversity in a region may lead to-
The plant production is declining, resistance to the environment conditions are decreased, such as drought, the unwanted changes in climate which in result drying out some species because of unadaptable conditions.

Note: Human activities are responsible for the increasing rates of the extinction of the species. The major causes of biodiversity losses are-
The important cause for driving animals and plants to extinction is habitat loss and deforestation.
Over-exploitation- Humans dependency or need for food and shelter on nature is turning into greed and is leading to the over-exploitation of natural resources.
Alien species invasions – sometimes the arrival of new species brings complications.
Co-extinctions – declining in the rate of host species resulting in the loss or endangerment of the other species.
