Producers
- THESE ARE USUALLY PLANTS BECAUSE THEY PRODUCE ENERGY BY MEANS OF ............
-SOMETIMES IT CAN ALSO BE PHYTOPLANKTON OR BACTERIA.

  • The amount of individual organisms in the community reflected in a pyramid.
  • Each trophic level of a food chain is represented with a bar. 
  • The amount of individuals in each trophic leel is represented by the size of the bar. 

Slide 13 - Slide

Pyramid of biomass:
  • The total biomass of all organisms in the community reflected in a pyramid.
  • The total bimass of each trophic level of a food chain is represented with a bar. 
  • The amount organisms in each trophic level is multiplied by the mass of each individual to get the biomass.

PROJECT SPRINT 3:
  • a food chain / food web including your apex predator
  • BONUS - EXTRA: CREATE A PYRAMID OF NUMBERS OF BIOMASS SHOWING THE POSITION OF YOUR APEX PREDATOR WITHIN THE ECOSYSTEM. (50 WORDS AND A PICTURE FOR EVERY TROPHIC LEVEL)
  • Explain how your apex predator has specialised for hunting its prey and how has the prey adapted to survive. (250 words) 
  •  BONUS - EXTRA: (250 WORDS AND PICTURES)
  • HOW IS YOUR APEX PREDATOR PLACED ON THE WORLD EXTINCTION LIST
  • WHAT IS/CAN BE DONE TO PROTECT THEM
