Temperate Deciduous Forests
Abiotic Factors + Importance
Biotic Factors (Plants + Animals)
Biotic Interactions, Biotic + Abiotic Interactions
Major Human Impacts
Ten thousand years ago plants covered half of the earth's surface. Now they only cover about one third. Many forests that have disappeared have regrown but some are lost forever. People cut down forests for many reasons, sometimes to build houses other times to make paper. In the case of a healthy forest, the land under is filled with rich soil great for farming. If farmers choose to cut down these forests they may get great quality crops, but the forest that was once there may never grow back. People need paper to write and create books, but because of this trees are being cut down.
Geographic Locations Within Canada
By Mia Kruger, Sarah Graham and Sophie Greer
Temperate Deciduous Forests are located in in Eastern Canada. The lighter green parts of this map are the temperate deciduous forests.
Photosynthesis
Temperature just right for growth of deciduous trees
Shelter for certain animals
Major Abiotic Factors:
Soil- very rich with lots of nutrients
Sunlight- helps with photosynthesis and plant growth
Oxygen-produced by plants, necessary for cellular respiration
Temperature- mild (temperate). Helps plant growth
Rocks- rocks and hills/mountains can provide habitats for animals
How the climate affects the ecosystem
The climate of the Canadian temperate forests affect the organisms living inside of it. The word "temperate" means not too hot, nor too cold. To be specific, over the course of a year, the average temperature ranges from -1 to 32 degrees Celsius. These mild conditions provide stable growth for the biotic factors within this habitat. Many plant species have adapted to absorb and store water on the snowier or rainier days in this ecosystem and absorb sunlight on the sunnier days to take advantage of this temperate climate. As for the animals, many species travel to different regions of the ecosystem depending on the season.

Biotic Interactions include the animals interacting with each other and with the plants and trees. Biotic and Abiotic interactions include animals interacting with a dead tree or snow falling on animals or living plants. There are a couple examples in this picture:
