3. CHANGES IN THE ECOSYSTEM
4. Interactions and transformations
4.1. Biotic-Biotic, EX: Bears need to feed on fish to survive so the population of fishes eventually decreases.
4.2. Abiotic-Biotic: EX: The sun and the rain make plants grow wich produce the oxygen other living organisms need to live
4.3. Biotic-Abiotic: EX: Herbivore animals such as rabbits need to eat plants to survive and then be eaten by predators making food chain.
4.4. MASS-MASS: EX: paper into ashes
4.5. Mass-energy, EX: The combustion of wood in a bonfire: wood changes producing heat and smoke
4.6. Energy-energy: Thermal Energy
5. MATTER
5.1. Mass: how matter exists in form of particles. It is the measurement of the quantity of matter that a body has.
5.2. Energy: Is the capacity to perform work or produce a change.
5.2.1. Kinetic energy: (movement)
5.2.2. Potential energy: (rest)
