- Classification
- Energy Flow
- Arrows indicate where energy is being transferred to.
- Energy can be lost at every trophic level due to egestion,
excretion and heat loss.
- Energy Efficiency = (Energy into Biomass / Total Energy) X 100
- Pyramid of Biomass can be hard to construct because:
- Organisms may belong to more than 1 trophic level
- Problems measuring dry biomass e.g. a tree.
- Pyramids of Biomass show the dry mass
of living material at each trophic level
- Recycling
- Carbon and Nitrogen are two recycled elements
- Carbon Cycle is displays how carbon is
recycled around Earth
- The Nitrogen Cycle
demonstrates how nitrogen
is recycled around Earth
- Animals or plants incorporate these elements in their body
- Interdependence
- Adaptations
- Natural Selection
- Population and Pollution
- Sustainability
