Interactions and Ecosystems

Predator-prey relationships can be graphed
Food webs show energy flow
Energy flows through ecological pyramids
Primary succession differs from secondary succession
Ecosystems have abiotic (non-living) and biotic (living) components
Symbiosis includes commensalism, mutualism, and parasitism examples
Ecological footprint measures environmental impact; activities affect it
Key terms related to endangered species, migration, extinction, behavioral/structural adaptations.
Concepts of deforestation and its consequences
Types of consumers: carnivores, herbivores, omnivores
Predator-prey relationships exist in ecosystems
Producers (plants) and their role in ecosystems
Biodiversity is essential in terms of ecosystem health

Heat and Temperature

Particle model to explain matter (solids, liquids, gases)
Phase changes (sublimation, condensation, freezing, melting, evaporation, deposition) and their properties
Methods of heat transfer (conduction, convection, radiation)
Insulators vs. conductors of heat
Using thermometers to measure temperature
Understanding different types of variables (manipulated, responding, controlled)
Advantages and disadvantages of energy sources like oil, gas, nuclear, solar, and hydropower
Key terms about thermal energy, temperature, expansion, and contraction
Energy sources classified as renewable or non-renewable
The concept of kinetic energy

Explore the intricate relationships within ecosystems, including predator-prey dynamics, food webs, and energy flow through ecological pyramids. Understand the differences between primary and secondary succession, and the importance of biodiversity and ecological footprints. Delve into the roles of producers and various types of consumers in maintaining ecosystem health.
