Introduction • Ecology is the study of the environment and all of its organisms. Such organisms include soil, rocks, worms, birds, insects, and other living creatures and non living objects.
Vocabulary Pollution- contamination; undesirable state of the natural environment Grass- narrow leaved herbage; what makes up lawns Acid rain- rain including acids from the atmosphere such as sulfur dioxide Soil- the earth's surface consisting of humus and disintegrated rock Bird-warm-blooded egg-laying vertebrates characterized by feathers and forelimbs modified as wings Horizon- a specific layer or stratum of soil or subsoil in a vertical cross section of land
Vocabulary (Cont’d) Tree- a figure that branches from a single root Dirt- the unclean (unsanitary) part of soil Subsoil- layer of soil very low in organic material Organic- relating or belonging to the class of chemical compounds having a carbon basis Weathering- decomposition of Earth rocks, soils and their minerals through direct contact with the planet's atmosphere Erosion-earth's surface is worn away by the action of water and wind
Site Map Bradford drew a picture of the sites around Renaissance that we visited. Our main concern was with the front of the building. As you can see we took soil samples from the garden there.
Site Map (Cont’d) This is the front view of out site map. It includes the trees, rocks, grass and organisms that we studied.
Soil Samples • Our Samples: Online Diagram A Horizon- Top soil

Site comparisons RolliePollie- small air-breathing arthropod Spider-predatory arachnid with eight legs, two poison fangs, two feelers, and usually two silk-spinning organs at the back end of the body
Site comparisons (Cont’d) • Sub soil- the layer of soil between the topsoil and bedrock • This is where most of the organisms are found. Because there is so much oxygen found in the layers of sub soil it is very easy for animals to survive.
Zone of leaching Zone of leaching- The layer of soil just beneath the topsoil where water percolates, removing soluble nutrients that accumulate in the subsoil. Water is often purer in the zone of leaching because it has been filtered by the top soil
