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
