4.Ecological crisis :-An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include: Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls) Increased pressures from predation.

5.Tundra :- In physical geography, tundra is a type of biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sámi word тӯндар meaning "uplands", "treeless mountain tract".
