- no eco-system is perfect
- some output is always lost
- Recycling waste products
- Photosynthesis produces oxygen which is used in repiration
- Carbon
- CO2 - photosynthesis - O2 - respiration - CO2
- released during combustion
- Reproductive strategies
- organisms have different approaches
- fish and amphibians produce a lot of eggs
- more reproduction, the higher chance of survival
- unsuccesful fertilities are recycled in the system
- organisms have different approaches
- Vegetation
- essential in the ecosystem
- photosynthesis
- roots help stabilise soil
- Transpiration from trees encourages cloud formation
- Trees provide shade
- essential in the ecosystem
- Humans affect the Ecosystem
- rely on the natural ecosystem
- pollination of crops
- not closed loop
- mainly negative impacts
- harvesting causing soil erosion
- unbalancing food web
- replacement of nature for biofuels
- can cause reduced amount of fresh water
- rely on the natural ecosystem
- sustainability
- removal = reproduction
- using what we need for today without harming the future
- renewable energy
- wind
- solar
- hydro
- Bioaccumalation
- toxins build up in food chains
- Eutrophication
- 1. fertilizers enter water
- causing algae to form
- causing light to be blocked
- reducing oxygen in water
- causing plant and animals to die .
