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.
VocabularyPollution- contamination; undesirable state of
the natural environment Grass- narrow leaved herbage; what makes up
lawnsAcid 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 materialOrganic- relating or belonging to the class of chemical
compounds having a carbon basisWeathering- 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.

Site comparisons
Rollie Pollie- 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
