Ecosystems Notes

Geography: Ecosystems at Risk.
Biophysical interactions which lead to several(a) ecosystems and their functioning:
* Characterised by the interactions between abiotic (non-living) and biotic (living) environments.
* Biosphere, lithosphere, hydrosphere and the atmosphere- significant role in functioning.
* Interactions of diverse species produce the complexity of ecosystems across the world.
Abiotic Influences:
* Celestial influences- sun and daydream influencing amount of day, night, heat, light and pull on earth.
* Earth influences- oceansonal worker changes, rainfall, temperature, wind patterns, tidal change and ocean currents.
* Chemical influences- sea spray blown inland, nutrient upwelling in oceans and fallout from the atmosphere.
* study events- Tsunamis, volcanos, fires and storms.
Biotic Influences:
* Life cycles- food chain relationships.
* Migration behaviour patterns- botany (cross-pollination) and animals.
* Population dynamics- influences species interactions through increase and decrease.
* Adaptions- Distribution of species deep down an ecosystem.
* Species interactions- maintenance, wellness and functioning of ecosystems.
What is biodiversity?
* Variety of life forms that are best fit to survive the current conditions on earth.




* Genetic diversity- variations of genetics within a specific species.
* Species diversity- variety of species within a habitat.
* ecologic diversity- variety of biological communities that interact with each other and non-living environment.
study living components of ecosystems:
* Ecosystems work through the interactions of energy and matter that feed ins between biotic and abiotic components.
* Each organism has a role to play in the flow of energy and cycle of matter.
* Living organisms= Producers or consumers.
* Producers make their own food from substances obtained in their environment.
* Photosynthesis and chemosynthesis= process by which...If you want to get a enough essay, order it on our website: Orderessay
