Document Summary
Winter-predict where animals going to be depending on food. Total number of species of flora and fauna=biodiversity. Reptiles and amphibians=herptiles=herps-snapping turtle, milk snake,hog nose snake, red back salamanders, red bullfrogs- 50 species. Total vascular plants, bryophytes and fungi >10,000 species. 2) great range of abiotic factors- conditions-abiotic=non-living, range of environmental. Lichens-bryophytes=>800 species conditions such as temperature-range dramatically-precipitation(rain and snow)-wind, snow with sand on it-soil type,plants need soil to grow-fire,essential. Rocks, made of minerals that affect the nutrient supply and soil chemistry, the rock under any given area is called bedrock. Some bedrock is flat and layered, these rocks are formed from sediments and are called sedimentary rocks=young rocks 400-500 million yrs old. Limestone is a sedimentary rock, this rock is rich in calcium (calcium carbonate ) and is relatively soft and basic in ph. Some limestone is made from animals whose fossil remains are full of calcium. Poison ivy loves basic soil and calcium-calciphiles.
