What are the four main human activities that cause a loss of biodiversity?

a. Preservation, habitat destruction, overharvesting, and use of chemical pollutants

b. Habitat destruction, invasive species displacement, use of chemical pollutants, and overharvesting

c. Overharvesting, conservation, use of chemical pollutants, and invasive species displacement

d. conservation, preservation, use of chemical pollutants, and overharvesting

e. Habitat destruction, overharvesting, conservation, and use of chemical pollutants

The correct answer will be option-B.

Explanation:

Biodiversity represents the variety of the biological organism-form microorganism to plant and animals in any particular habitat.

The biodiversity loss is a serious problem in the modern world which is caused by the growth rate of humans and resource exploitation.

Humans depend on the natural resources for their use due to which they modify the natural area leading to the habitat loss. They over-harvest the natural resources like aquatic organisms mainly fishery industry.

The growth rate of humans has forced us, humans, to increase productivity in every area sue to which humans use harmful chemicals like pesticides and insecticides which directly affect biodiversity. it leads to algal bloom and eutrophication of small water bodies.

The introduction of exotic species to any area results in the displacement of the invasive species of the area which directly affects the natural habitat.

Thus, Option-B is the correct answer.

The Correct answer is B

Explanation:

The loss of biodiversity can be focused on the activities of Human beings on the world's ecosystem which is the major cause of its loss. Overexploitation of natural resources is the human activities which are the major cause of biodiversity loss. Population growth and overconsumption is one of the major cause of Human activity which is responsible for the loss of Biodiversity.
