Study Notes
Biome Overview
- A biome is a large ecological area with similar climate, plants, and animals.
- Examples of biomes include forests, deserts, and grasslands.
Biosphere Definition
- The biosphere encompasses all locations on Earth where life exists, including living organisms and their habitats.
Types of Biomes in Ontario
- Ontario features four main biomes:
- Deciduous Forest: Characterized by trees shedding leaves in autumn (e.g., oak, maple), diverse wildlife, and rich soil with four distinct seasons.
- Boreal Forest (Taiga): Dominated by coniferous trees (e.g., spruce, fir, pine), experiences cold climates with long winters and short summers, and has acidic, nutrient-poor soil.
- Tundra: Characterized by very cold temperatures, short growing seasons, the presence of permafrost, and low vegetation like mosses and lichens.
- Grasslands: Dominated by grasses, sparse trees, varied climates, and frequent fires which support the grassland ecosystem.
Ecological Relationships
- Individual Organism: A single living entity, e.g., a lion.
- Population: A group of the same species, e.g., a pride of lions.
- Community: Different populations living together, e.g., lions, zebras, and trees in a savanna.
- Ecosystem: A community plus its environment, e.g., the savanna including soil and water.
- Biome: A large area containing similar ecosystems and climates, e.g., the African savanna biome.
Components of the Biosphere
- Lithosphere: The solid outer layer of Earth, comprising rocks, soil, and landforms like mountains and valleys.
- Atmosphere: The layer of gases surrounding Earth, crucial for life, includes air we breathe (oxygen and carbon dioxide).
- Hydrosphere: Encompasses all Earth's water bodies, including oceans, lakes, rivers, and glaciers.
Terrestrial and Aquatic Biomes
-
Terrestrial Biomes:
- Forests (tropical, temperate, boreal)
- Grasslands
- Deserts
- Tundra
-
Aquatic Biomes:
- Freshwater (lakes, rivers, wetlands)
- Marine (oceans, coral reefs, estuaries)
Comparison of Deciduous and Boreal Forests
-
Deciduous Forest:
- Trees lose leaves annually.
- Rich, fertile soil with diverse wildlife (e.g., deer, various birds).
- Experiences four distinct seasons.
-
Boreal Forest:
- Composed mainly of coniferous trees.
- Has a cold climate with long winters and short summers.
- Soil is acidic and nutrient-poor, habitats for species like moose and wolves.
Similarities Among Biomes
- All biomes contain unique plants and animals adapted to specific climates.
- Climate and geographic conditions shape each biome.
- Every biome is an integral part of the Earth's biosphere, contributing to the overall system of life.
