Biology 2201

Unit 1: Ecosystem Interaction and Population Dynamics

Populations, energy flow, biomes, and the limits to growth — how living things interact and what bounds their numbers. STSE risk/benefit framing and inquiry skills are woven through.

• Interactions within and between populations
• Energy pyramids and food resources

• Comparing Canadian biomes
• Population growth and its factors
• Earth's carrying capacity

Unit 2: Processes that Sustain Life

The cell — its theory, structure, chemistry, transport, and the energy transformations of respiration and photosynthesis. STSE nature-of-science framing and inquiry skills are woven through.

• The cell theory
• Prokaryotic, eukaryotic, plant, and animal cells
• Cell structures under light and electron microscopes

• Elements and compounds in living systems
• Water, glucose, and ATP
• Carbohydrates, lipids, and proteins
• How organelles manage transport
• Respiration and photosynthesis energetics

Unit 3: Maintaining Homeostasis

How feedback keeps internal conditions stable — in plants and across the human nervous, endocrine, circulatory, respiratory, digestive, and excretory systems, plus the roles of fitness and nutrition. STSE decision-framing and inquiry skills are woven through.

• Feedback mechanisms and homeostasis
• Plant structure and homeostasis
• Tropisms

• The nervous system and homeostasis
• External factors on the nervous system
• Disorders and diseases on homeostasis
• The endocrine system and homeostasis

• The circulatory system and homeostasis
• Fitness and homeostasis
• Environmental factors on homeostasis
• The respiratory system and homeostasis
• The digestive system and homeostasis
• Nutrition and homeostasis
• The excretory system and homeostasis
