In this persentation I give a short description about ecology and the history of it. I also show the ecological crisis as well as environmental situation for ethical and social awareness.

1. Ecology

12. Individual Population Population interactions Community Ecosystem Landscape Region = Biome Biosphere “ Levels” of Ecology

15. Tropical Forest: Vertical stratification with trees in canopy blocking light to bottom strata. Many trees covered by epiphytes (plants that grow on other plants).

17. Desert: Sparse rainfall (< 30 cm per year), plants and animals adapted for water storage and conservation. Can be either very, very hot, or very cold (e.g. Antarctica )

18. Coniferous forest: Largest terrestial biome on earth, old growth forests rapidly disappearing, usually receives lots of moisture as rain or snow.

19. Tundra: Permafrost (Permanent frozen ground), bitter cold, high winds and thus no trees. Has 20% of land surface on earth.
