B3 - Living together - food and ecosystems

In this unit we look at the how organisms live together. The unit is split into 4 parts…

  • In unit B3.1 we look at what happens in photosynthesis and how enzymes function to play a role in this.
  • In unit B3.2 we look at how producers get the substances they need through diffusion, osmosis and active transport.
  • In unit B3.3 we look at how ecosystems are interdependent.
  • In unit B3.4 we look at how populations are affected by conditions in the environment and how we can sample for populations size using fieldwork.
