Biomes & Ecological Succession - Complete Interactive Lesson
Part 1: Core Concepts
🌍 Biomes & Ecological Succession
Part 1 of 7 — Terrestrial and Aquatic Biomes
Terrestrial Biomes
| Biome | Climate | Key Features | Biodiversity |
|---|---|---|---|
| Tropical rainforest | Hot, wet year-round | Tallest canopy, most diverse biome | Highest |
| Tropical savanna | Hot, distinct wet/dry seasons | Grassland with scattered trees, fire-adapted | High |
| Desert | Hot or cold, <25 cm rain/yr | Sparse vegetation, extreme temperature swings | Low |
| Temperate grassland | Moderate temps, 25-75 cm rain | Deep fertile soil (great for agriculture) | Moderate |
| Temperate forest | Moderate, distinct seasons | Deciduous trees, autumn leaf drop | Moderate-High |
| Boreal forest (taiga) | Cold, long winters | Coniferous trees (spruce, pine, fir) | Low-Moderate |
| Tundra | Very cold, permafrost | No trees; mosses, lichens, low shrubs | Low |
🔑 Biome distribution is primarily determined by temperature and precipitation — this is why biomes form latitudinal bands.

Ecological Succession
| Type | Starting Point | Process | Example |
|---|---|---|---|
| Primary succession | Bare rock/new surface (no soil) | Pioneer species → soil development → complex community | Lava flow, retreating glacier |
| Secondary succession | Disturbed area (soil remains) | Faster recovery since soil exists | After fire, abandoned farm, hurricane |
Succession Stages (Primary)
- Pioneer species arrive: lichens, mosses break down rock
- Soil develops from weathered rock + dead organisms
- Grasses and herbs colonize the new thin soil
- Shrubs and small trees outcompete grasses for light
- Climax community established: mature forest or stable ecosystem
Key Terms
| Term | Definition |
|---|---|
| Pioneer species | First to colonize; tolerant of harsh conditions (lichens, mosses) |
| Climax community | Stable, mature endpoint of succession |
Applied Recall ✍️
-
Succession that begins on bare rock with no soil is called _______ succession.
-
The first organisms to colonize a disturbed or new area are called _______ species.
-
The stable, mature endpoint of succession is called the _______ community.
Classify the Scenario 🔍
AP Exam Strategy: Biomes & Succession
- Know how to read a climate diagram (climograph) showing temperature and precipitation to identify biomes
- Primary vs secondary succession: the KEY difference is whether soil is present
- Fire is NOT always bad — many ecosystems (grasslands, chaparral, pine forests) are fire-adapted and NEED periodic burning
- Invasive species can disrupt succession by outcompeting native species
- Permafrost thawing due to climate change releases methane — a positive feedback loop
