PRODUCT DESCRIPTION

This 14-slide powerpoint presentation covers 'Topic 4.2 - Energy Flow' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into two sections:

A - Food Chains
B - Energy Loss

The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or

revision. Please see the preview file for an idea of the slide aesthetic and level of detail.

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!


Learning Objectives:

U1: Most ecosystems rely on a supply of energy from sunlight.
U2: Light energy is converted to chemical energy in carbon compounds by photosynthesis.
U3: Chemical energy in carbon compounds flows through food chains by means of feeding.
U4: Energy released from carbon compounds by respiration is used in living organisms and converted to heat.
U5: Living organisms cannot convert heat to other forms of energy.
U6: Heat is lost from ecosystems.
U7: Energy losses between trophic levels restrict the length of food chains and the biomass of higher trophic levels.
S1: Quantitative representations of energy flow using pyramids of energy.
