Carbon cycle
Planten hebben koolstof nodig voor fotosynthese, hiervoor nemen zijn koolstofdioxide (CO2) op. Zij zetten dit om naar energierijk glucose (C6 H12 O6). Dit word verbrand door alle levende wezens, daarmee zetten zij het weer om naar CO2.
Slide 6 - Slide
Degradable
It is important that nature knows what to do with what is dumped in it. That is why it is important that things that end up in nature are biodegradable. This way the material can be reused by other organisms and has no negative effects on health.
