Unit 1 · 5 skills
Ecosystem Interaction and Population Dynamics
Populations and energy flow
Interactions within and between populations
I can analyze interactions within and between populations, including competition, predation, and the symbioses (mutualism, commensalism, parasitism).
Skill 1.1
Energy pyramids and food resources
I can use the energy pyramid to explain the production, distribution, and use of food resources, applying the ~10% rule between trophic levels.
Skill 1.2
Biomes and carrying capacity
Comparing Canadian biomes
I can compare Canadian biomes in terms of climate, vegetation, physical geography, and location.
Skill 1.3
Population growth and its factors
I can describe population growth and explain the factors that influence it, distinguishing exponential from logistic growth.
Skill 1.4
Earth's carrying capacity
I can evaluate Earth's carrying capacity, weighing human population growth against demands on natural resources.

Key ideas
Intraspecific interactions (within one population) are dominated by competition for the same niche resources.
A biome is defined primarily by climate (temperature and precipitation), which selects its characteristic vegetation.
Interspecific interactions (between populations): competition, predation, and symbiosis (mutualism +/+, commensalism +/0, parasitism +/-).
Canada's major biomes: tundra, boreal forest (taiga), temperate deciduous forest, grassland.
Predator-prey numbers cycle with a lag — prey rises, predators follow, prey crashes, predators crash.
Watch out for
- That predators 'control' prey by deliberate restraint — the cycling is a lagged feedback, not a plan.
- That soil type defines a biome — climate is primary; soil follows from climate and vegetation.
- That symbiosis always means both partners benefit — only mutualism is +/+.

Processes that Sustain Life
Cell theory and cell structure
The cell theory
I can explain the cell theory and the observations that support its three principles.
Skill 2.1
Prokaryotic, eukaryotic, plant, and animal cells
I can compare and contrast prokaryotic vs eukaryotic cells and plant vs animal cells by their defining structures.
Skill 2.2
Cell structures under light and electron microscopes
I can describe which cell structures are visible with light versus electron microscopes and why.
Skill 2.3
The chemistry of living systems
Elements and compounds in living systems
I can identify the chemical elements and compounds commonly found in living systems.
Skill 2.4
Water, glucose, and ATP
I can identify the roles of water, glucose, and ATP in living systems.
Skill 2.5
Carbohydrates, lipids, and proteins
I can identify and describe the components and functions of carbohydrates, lipids, and proteins.
Skill 2.6
How organelles manage transport
I can describe how the cell manages passive transport, active transport, and membrane-assisted transport.
Skill 2.7
Respiration and photosynthesis energetics
I can compare and contrast the matter and energy transformations of aerobic respiration and photosynthesis.

Key ideas
All living things are made of one or more cells.
The 'CHNOPS' elements — carbon, hydrogen, nitrogen, oxygen, phosphorus, sulfur — make up most of living matter.
The cell is the basic unit of structure and function in life.
Compounds are inorganic (water, salts) or organic (carbon-based: carbohydrates, lipids, proteins, nucleic acids).
All cells arise from pre-existing cells (Virchow) — refuting spontaneous generation.
Watch out for
- That some organisms are alive without being cellular (viruses are the edge case, not a counterexample to the theory).
- That 'organic' means natural or pesticide-free — in chemistry it means carbon-based.
- That cells can form spontaneously from non-living matter today.

Maintaining Homeostasis
Feedback and homeostasis in plants
Feedback mechanisms and homeostasis
I can explain how feedback mechanisms maintain homeostasis, distinguishing negative from positive feedback.
Skill 3.1
Plant structure and homeostasis
I can explain how plant structures and processes (transpiration, stomata) maintain homeostasis.
Skill 3.2
Tropisms
I can explain how tropisms (growth responses to stimuli) help plants maintain homeostasis.
Skill 3.3
Human control systems: nervous and endocrine
The nervous system and homeostasis
I can explain how the human nervous system maintains homeostasis through rapid signalling.
Skill 3.4
External factors on the nervous system
I can analyze how an external factor (such as a drug) disrupts the homeostasis of the nervous system.
Skill 3.5
Disorders and diseases on homeostasis
I can evaluate how disorders and diseases disrupt homeostasis.
Skill 3.6
The endocrine system and homeostasis
I can explain how the endocrine system contributes to homeostasis through hormones.

Key ideas
Homeostasis is the maintenance of a stable internal environment despite external change.
Neurons carry electrical impulses; the CNS (brain, spinal cord) integrates, the PNS relays.
The heart pumps blood through arteries, capillaries, and veins in a double circuit.
Negative feedback reverses a change back toward a set point (most homeostatic control).
A stimulus -> receptor -> sensory neuron -> CNS -> motor neuron -> effector pathway.
Watch out for
- That homeostasis means conditions never change — it means they oscillate around a set point.
- That nerve impulses travel like electricity in a wire — they are electrochemical waves.
- That blood only carries oxygen — it transports many things at once.
