Here's a detailed breakdown of each summarized learning intention: \#\#\# 1. \*\*Ecosystems & Components\*\* \- \*\*Key Goal\*\*: Describe what ecosystems are and identify their different parts. \- \*\*What to Know\*\*: \- Use terms like \*biosphere, ecosystem, biotic, abiotic,\* and \*habitat\* correctly. \- An ecosystem includes living (biotic) and non-living (abiotic) components interacting with each other. \- Recognize examples of abiotic factors (like sunlight, water, and soil) and biotic factors (like plants, animals, and bacteria). \- Understand that abiotic factors can change within an ecosystem, such as in a forest versus a rock pool. \#\#\# 2. \*\*Organism Interactions\*\* \- \*\*Key Goal\*\*: Identify and describe how living things interact in an ecosystem. \- \*\*What to Know\*\*: \- Understand interactions like \*collaboration\* (working together), \*mating\* (reproduction), \*competition\* (fighting for resources), and \*symbiosis\* (close relationships). \- Describe examples of symbiotic relationships, including \*mutualism\* (both benefit), \*commensalism\* (one benefits, the other is unaffected), and \*parasitism\* (one benefits, the other is harmed). \- Explain predator-prey relationships and how these affect populations over time. \#\#\# 3. \*\*Impact of Invasive Species\*\* \- \*\*Key Goal\*\*: Explain how invasive species disrupt ecosystems. \- \*\*What to Know\*\*: \- Define terms like \*biological control\* (using living organisms to control pests) and \*invasive species\* (organisms that cause harm when introduced to new environments). \- Discuss examples, such as the impact of invasive species in Australia. \- Explain why Myxoma is less effective on rabbits now, touching on natural selection. \#\#\# 4. \*\*Energy Flow in Ecosystems\*\* \- \*\*Key Goal\*\*: Understand how energy moves through ecosystems. \- \*\*What to Know\*\*: \- Define \*trophic levels\* (like producers, consumers, and apex predators) and explain how energy is transferred through food chains as glucose. \- Understand only about 10% of energy transfers to the next trophic level. \- Know terms like \*herbivore, carnivore, biomass,\* and \*apex predator\* and the role of decomposers in recycling energy. \#\#\# 5. \*\*Human Impact on Ecosystems\*\* \- \*\*Key Goal\*\*: Relate human activities to environmental damage. \- \*\*What to Know\*\*: \- Describe the \*enhanced greenhouse effect\* and its causes, like increased CO₂ emissions. \- Give examples of how humans disrupt ecosystems, such as deforestation or pollution. \- Understand how a growing human population increases ecological pressure.
