Loss of biodiversity and accelerations of extinction rates...

Loss of biodiversity and accelerations of extinction rates have several causes. Which of the following situations causes direct loss of biodiversity owing to loss of habitat? a. fishing cod at a rate that is greater than natural replacement b. converting a prairie to a farm field c. introduction of an invasive ornamental plant in a new ecosystem d. emission of greenhouse gases increasing the average temperatures of an area

Key Concepts

Biodiversity

Biodiversity refers to the variety of life in all its forms, including the genetic variations within species, the diversity of species themselves, and the range of ecosystems they form. It is a measure of the health of biological systems and is essential for ecosystem resilience, stability, and the provision of ecosystem services such as pollination, water purification, and nutrient cycling.

Habitat Loss

Habitat loss is the direct reduction in the availability of natural environments where species have evolved and adapted to live. This loss can result from various human activities such as urban development, agriculture, and deforestation. The removal or significant alteration of these habitats leads to decreased biodiversity as species lose the necessary conditions to survive, breed, and maintain healthy populations.

Human-induced Habitat Conversion

Human-induced habitat conversion is a specific form of habitat loss where natural landscapes are transformed to meet human needs, such as converting prairies, forests, or wetlands into agricultural fields or urban areas. This conversion not only eliminates the original habitat, directly reducing the number of species that can thrive there, but also fragments the remaining natural areas, further hindering species' ability to survive and reproduce.
