What to Focus On

  • Tansley coined the term Ecosystem in 1935.
  • An ecosystem is self-sustaining and self-regulating.
  • Energy flow is unidirectional, while nutrients cycle.
  • Habitat loss is the greatest threat to biodiversity.
  • Tropical rain forests have declined from 14% to 6%.
  • More than 50% of wetlands in the US have been destroyed in 200 years.
  • Genetic erosion means shrinkage of the gene pool in endangered species.
  • Habitat fragmentation increases genetic erosion.
  • Low genetic diversity weakens immunity and survival.

Common Mistakes to Avoid

In situ conservation and ex situ conservation mean the same thing.

National parks and sanctuaries are the same because both are protected areas.

Biosphere reserve zones are arranged from least protected at the center to most protected at the edge.
