Energy flow 4.2
This topic is all about the way that energy from sunlight is trapped by photosynthesis and then passed from organism to organism in a food web. We can call this the transfer of energy within food webs. Being able to describe the path taken by the en…

Carbon Cycle 4.3
The processes of the carbon cycle include photosynthesis and respiration which are well known, but this topic gets tricky in other connected aspects of the global carbon cycle. These include storage of carbon containing molecules in peat, fossil fuel…
