Summary
This document summarizes different ecosystems and biomes, including extinct and endangered species. It details various types of ecosystems, such as grasslands, boreal forests, and mountain forests, and their characteristics. The document also discusses marine and freshwater ecosystems, emphasizing their biogeochemical processes and salt concentrations.

Extinct: Found nowhere in the world. Ex: Great Auk, Passenger Pigeon, Sea Mink. Extirpated: No longer exist in a specific area. Ex: Atlantic Walrus, Paddlefish, Greater Prairie Chicken. Endangered: Imminent danger of being extirpated or going extinct. Ex: Barn Owl, Swift Fox, Northern Cricket Frog...
Extinct: Found nowhere in the world. Ex: Great Auk, Passenger Pigeon, Sea Mink. Extirpated: No longer exist in a specific area. Ex: Atlantic Walrus, Paddlefish, Greater Prairie Chicken. Endangered: Imminent danger of being extirpated or going extinct. Ex: Barn Owl, Swift Fox, Northern Cricket Frog. Threatened: Likely to become endangered if limiting factors are not reversed. Ex: Humpback Whale, Wood Bison, Kentucky, Coffee Tree. Special Concern: May become threatened if a combination of factors do not improve. Ex: Polar Bear, Red Headed, Woodpecker, Atlantic Cod. Grasslands: Smallest biome found in parts of Ontario and Quebec where many deciduous trees grow and the soil is fertile. Warm, dry summers. Boreal Forest: Largest biome in Canada that contains many coniferous trees making the soil. Acidic along with warm summers and rainfall. Mountain Forest: Found mainly in British Columbia with many mountains, many coniferous trees and lots of elevation Tundra: Low temperature, low biodiversity and rapid flowering plants. Temperate Deciduous Forest: Found in the prairies, has lots of grass and very fertile soil and long growing seasons. Marine or Ocean ecosystems: Marine ecosystems are an important part of biogeochemical cycles. Most of the water that evaporates into the air and falls as rain and snow comes from oceans. Ocean, or marine ecosystems have salt concentrations averaging about 3 %. Freshwater ecosystems:Freshwater ecosystems consist of moving bodies of water, such as rivers, and nearly stationary bodies of water, such as lakes. Freshwater ecosystems have salt concentrations that are typically below 1 %.
