Summary notes and past exam questions by topic for AQA Biology A-Level Topic 5 - Energy Transfers In and Between Organisms.
The term energy transfer refers to the changes in energy that occur in and between organisms within an ecosystem. Autotrophs and heterotrophs are involved in energy transfer. Autotrophs are able to synthesize their own energy, whilst heterotrophs have to consume other organisms to gain energy.
All biological systems obey the laws of chemistry and physics, including the laws of thermodynamics that describe the properties and processes of energy transfer in systems. The first law states that the total amount of energy in the universe is constant; energy cannot be created or destroyed, but it can be transformed and transferred.
Energy transfer refers to the process by which energy moves from one form to another or from one object to another. In ecosystems, this concept is crucial for understanding how energy flows through food chains and webs, impacting organisms and their interactions.
