1	Use given data to construct a pyramid of numbers for a simple familiar food chain from a local habitat.
2	Construct simple food web diagrams based on observations of local habitat.
3	Relate the number and size of organisms to their position in the pyramid.
4	Examine and analyse the relative size and mass of organisms at each level of a familiar food chain to establish that the total mass of organisms at each stage decreases.
5	Relate the loss of total mass at each stage to the loss of energy.
6	Use given data to construct a pyramid of biomass for a simple familiar food chain from a local habitat.

Development of Target LT-F3.1
LT-F3.1	Construct and explain food pyramids
State that a pyramid of numbers is a way of representing the total population of each feeding level in a food web.
Be able to construct a pyramid of numbers from given data.
State that for each layer in a pyramid of numbers, generally, the total number of organisms at the upper layer is lower than the total number of organisms in the layer below.
State that a pyramid of biomass is a way of representing the total mass of all the organisms at
Be able to construct a pyramid of biomass from given data.
State that for each layer in a pyramid of biomass the total mass of organisms at the upper layer is always lower than the total mass of organisms in the layer below.
Explain the why a pyramid of biomass is always pyramid shaped.
