Types of Biomes in Ontario

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.
