Let's break down these energy transfer activities. Activity 11: Investigate energy transfer in biological systems 1. Horse eating grass (Figure 25): a) Energy stored in the grass: The energy stored in the grass is chemical potential energy*. b) What happens to this energy: When the grass reaches the horse's body, the chemical potential energy is converted into chemical potential energy (stored in the horse's tissues), kinetic energy (for movement), and thermal energy* (body heat). c) Energy flow diagram: Chemical potential energy (grass) digestion/metabolism Chemical potential energy (horse) movement/body processes Kinetic energy + Thermal energy 2. Athlete drinking an energy drink (Figure 2 - assumed): a) Energy stored in the energy drink: The energy stored in the energy drink is chemical potential energy*. b) What happens to this energy: When the drink reaches the athlete's body, the chemical potential energy is converted into chemical potential energy (stored in the athlete's body), kinetic energy (for movement), and thermal energy* (body heat). c) Energy flow diagram: Chemical potential energy (drink) digestion/metabolism Chemical potential energy (athlete) movement/body processes Kinetic energy + Thermal energy Activity 12: Identify potential and kinetic energy in systems Here is the completed table: | Example of an energy system | Indicate whether it is a mechanical, biological, thermal or electrical system | Identify the energy transferred in the system ✂️ _That answer was long and got cut off.
