(D) (iv) only

Answer 1

Hint:The variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural environment are all included in what is known as biodiversity.

Step by step solution:
 The various species and critters collaborate in complicated web-like ecosystems to keep things in balance and support life.
Genetic, species, and ecosystem diversity are the typical three levels of biodiversity that are covered. The various genes that each unique plant, animal, fungus, and bacterium have to constitute genetic variety. Ecosystem services like soil fertilization, nutrient recycling, management of pests and diseases, erosion prevention, and crop and tree pollination are all made possible by biodiversity. The three layers of biodiversity are genetic, species, and ecosystem. Genetic diversity describes the variations among members of a species and how well those members can vary with the environment. The total number of plant, animal, and insect species that can be found in a given area is referred to as the species diversity of that area.
The variety of living organisms found in various habitats is referred to as biodiversity. It is the variety of biological structures, from biomes to cellular macromolecules. Genetic diversity, species diversity, and ecological diversity are a few of the different levels at which biodiversity can be quantified.
So, option (D) is correct.
Note: Due to habitat loss, resource overuse, climate change, pollution, invasive exotic species, disease, poaching, etc., biodiversity is disappearing. It is crucial to preserve biodiversity since it offers us several moral and ethical advantages as well as aesthetic worth.
