Question

Evil Quartet is related with
A. Loss of biodiversity
B. Loss of alien species
C. Loss of standing crop
D. Loss of climax community

Answer 1

Hint: The planet faces an increased rate of species extinction, primarily due to human activity. Healthy habitats, living organisms' interdependent networks and their physical environment are vital to all life on Earth. We obtain clean air, fresh water , food, energy and medicine from our ecosystems.

Complete Answer:
The depletion of biodiversity is correlated with the Bad Quartet.

The four major causes of biodiversity loss are listed below:
- Loss and Fragmentation of Habitat
- Exploitation Over
- Invasions by Foreign Species(aliens)
- Co-extinction

- Loss of biodiversity, sometimes referred to as loss of biodiversity, a reduction of biodiversity within a species, an ecosystem, a geographical region or the whole of the Planet. Biodiversity is a concept that refers to the number of genes, habitats, individual organisms within a species, and the number of biological communities within a specified geographical area, from the smallest ecosystem to the global biosphere.
- The decline in the number, genetic variability, and variety of species, and the biological communities in a given area are also characterised by biodiversity loss. This loss in the variety of life will lead to a breakdown in the ecosystem's functioning where decline has occurred.
- Ecosystems are dramatically altered by natural ecological disturbances, such as wildfires, flooding, and volcanic eruptions, destroying local populations of certain animals and altering whole biological ecosystems. However, such disruptions are temporary, since natural disruptions are widespread and ecosystems have adapted to their challenges.

The correct Answer is option (A) Loss of biodiversity.

Note: In order to build incentives to preserve natural ecosystems and protect the biodiversity inside them from unnecessary harvesting, states, non-governmental organisations and the scientific community must work together while disincentivizing behaviour that leads to habitat loss and degradation.
