Answer: Option A. -> Habitat destruction
But sometimes extinctions happen at a higher and a faster rate than usual. Factors such as over-exploitation, large body size, small population, massive habitat loss and position at a higher trophic level favor extinction. A plant podophyllum is at the verge of extinction due to over-exploitation.

Answer: Option A. -> Co-evolution
The response of predator to prey and vice versa, over tens of thousands of years, produces physical and behavioral changes in a process known as coevolution. Coevolution can be mutually beneficial: many plants and pollinators have forms and behaviors that benefit each other.

Answer: Option D. -> Habitat destruction
The main cause of the loss of biodiversity can be attributed to the influence of human beings on the world’s ecosystem, In fact human beings have deeply altered the environment, and have modified the territory, exploiting the species directly, for example by fishing and hunting, changing the biogeochemical cycles and transferring species from one area to another of the planet.
