Show series of feeding relationships at different trophic levels
Numbers: show number of individuals at each trophic level
Biomass: show total dry mass of all individuals with trophic level
Energy: shows amount of energy passing through trophic level over lime
Denityfing Bacteria : nitrates as energy source + convert to nitrogen gas
Free livoing Nitrogen Fixing: Nitrogen gas to ammonia, to make amino acids and proteins.
Root Nodules Nitrogen Fixing: Ammonia - amino acids and other organic nitrogen containing compounds
Nitryfing Bacteria: Oxidise ammonia to nitrates
Releasing substances into the environment in amounts that cause harmful effects and which biological processes cannot easily remove.
Cutting down large areas of forests causes problems like destruction of habitats and global warming.

The net movement of particles from a region of high concentration to a region of low concentration i.e. down the concentration gradient
The net movement of water molecules from an area of high water concentration to an area of low water concentration across a selectively permeable membrane.
The movement of particles against a concentration gradient using energy
Water + Carbon Dioxide ----- Glucose + Oxygen
Convert light energy to chemical energy.
Any independent variable, increase in whose value leads to increase in value of dependent variable
