Answer :

Final answer:

The detailed answer covers various ecological concepts such as biogeography, nitrification, flora, niche, species, desertification, temperature distribution, estuaries, species diversity in the Andes, and CFCs.


Explanation:

Biogeography according to R.L Jones refers to the study of the geographical distribution of living organisms and the impact of factors like climate, geology, and evolution on their distribution.

  1. Nitrification is the process by which certain soil bacteria convert ammonium into nitrites and then into nitrates, essential for plant growth.
  2. Flora refers to the plant life in a particular region or period, including all forms of plant species.
  3. In ecology, a niche is the role or function of an organism or species within an ecosystem, including its interactions with the environment and other species.
  4. Species are groups of organisms that can interbreed and produce fertile offspring, sharing common characteristics.
  5. Desertification is the process of land degradation in arid, semi-arid, and dry sub-humid areas, often due to human activities like unsustainable agriculture and climate change.
  6. Tropical forests exhibit a relatively consistent temperature distribution characterized by high average temperatures throughout the year with minimal seasonal variation.
  7. Estuaries are partially enclosed coastal bodies of water where freshwater from rivers and streams meets and mixes with saltwater from the ocean.
  8. The Andes Mountain region is estimated to harbor a vast diversity of species, with approximately 30,000 plant species and a wide range of animal species.
  9. CFCs expand to Chlorofluorocarbons, which are synthetic compounds formerly used in various applications like refrigerants and aerosol propellants, contributing to ozone depletion.
