Document Summary
Biodiversity/biological diversity: the total number of species of flora and fauna in any given area. Ontario"s biodiversity: 100,000: reptiles and amphibians: herptiles (herps) 50 species, fish: 154 species, mammals: 81, birds: 490, invertebrates: 10,000+ Why is ontario"s biodiversity so rich: varying habitats, seasonality, large bodies of water, large land area. Precipitation: georgian bay is one of the wettest spots in ontario. Rocks: minerals and they supply plants with nutrition and effect the ph of the soil and its chemistry. Rocks are the foundation of ontario: the rock under any given area is called bedrock, it changes in form, flat, layers, height, (ex belleville), Layers are formed from sediments and are called sedimentary rocks, they are below water, they are young (400m years old) Limestone: rich in calcium (calcium carbonate) and is soft and basic (ph). When you pour hcl on it: bubbles, produces co2, effervesces, this proves there is calcium in there.
