Describe Abiotic and Biotic factors in your journal. Bell
Ringer
Slide 3
Ecology Study of the interactions among organisms and their
environment. Ecologists Scientists who study environmental
relationships Organize the environmental factors that influence
organisms into 2 groups ABIOTIC BIOTIC The Environment
Slide 4
Abiotic Non-living parts of the environment Examples: I.Water
II.Light & Temperature III.Air IV.Soil Comparing Abiotic and
Biotic Factors
Slide 5
Biotic Factors Living or once-living organisms in the
environment Examples: I.Levels or organization II.Population
III.Communities IV.Ecosystems V.Biomes VI.The Biosphere Comparing
Abiotic and Biotic Factors

Describe the biome in which we live. Must answer with at least
5 sentences. Be in depth and cover what is observed in this area.

5 Factors: Water Light Temperature Air Soil Abiotic
Factors
Slide 9
1.Water All organisms need water to survive Organisms are made
of 50%-95% water Respiration, photosynthesis, digestion, and other
important life process can only occur with presence of water 95% of
Earths surface water is found in oceans Abiotic Factors
Slide 10
Examples of Water Pacific Ocean-Kauai, Hawaii Cumberland River
& Lake Cumberland Dale Hollow Lake Bayou-Gueydan, LA
Slide 11
2. Light Availability of sun light is a major factor in
determining where green plants and other photosynthetic organisms
live Energy from Sun is changed into chemical energy Algae-lives
near water surface Dense forest have very little photosynthetic
plants, why? Abiotic Factors
Slide 12
Plant Examples North Shore-Kauai The Garden of Eden-Kauai Kipu
Ranch-Kauai -conifers
Slide 13
3.Temperature Regional temperature also determines which plants
and animals can live there Some areas of the world have fairly
consistent temperature year round Other areas have season during
which temperatures vary Arctic, Desert, Mid-Atlantic, Tropical,
Arid, and Mild Abiotic Factors
Slide 14
Temperature Variations Mojave Desert-CA Arctic Plain-Antarctica
Rain Forest-Brazil Great Plains-Kansas Appalachian Mts-TN Tropical
Island-FL Keys
Slide 15
4.Air Composed of a mixture of gases including Nitrogen,
Oxygen, and Carbon Dioxide. Plants & Animals depend on the
gases in air for respirations (breathe) All species are affected by
weather Weather- 8km to 16 km (from surface) Ozone Layer-20km to
50km (from surface) Few organisms live at extreme air pressures
Abiotic Factors
Slide 16
5.Soil Varies greatly from one environment to another Soil
Type-determined by amount of Sand, Silt, and Clay it contains
Various soils contains different amounts of nutrients, minerals,
and moisture Soil affects every organism in an environment! Abiotic
Factors
Slide 17
Soil Top Soil-rich in nutrients and moisture (plant crops) Red
Clay-sub soil-very acidic (use as filler dirt) Bed Rock-mostly
limestone/sandstone (paving stone)
Slide 18
Abiotic Factors do not provide everything an organism needs for
survival Organisms depend on other organisms for: Food Shelter
Protection Reproduction Biotic Factors
1.Organism : one individual from a population Levels of
Organization Mallard Drake GreenHead
Slide 21
2.Population : all of the individual of one species that live
in the same area at the same time. Levels of Organization
Slide 22
3.Community : the populations of different species that
interact in some way Levels of Organization
Slide 23
4.Ecosystem : all of the communities in an area and the abiotic
factors they interact with Levels of Organization
Slide 24
5.Biome : large region with plants and animals well adapted to
the soil and climate of the region Levels of Organization
Slide 25
6. Biosphere : The level of biological organization that is
made up of all the ecosystems on Earth Levels of Organization
Slide 26
Where Earths organisms live Can be found 11,000 m deep in the
ocean 9,000 m high on the mountains 4.5 km high in atmosphere
Includes top part of Earths crust, all the waters that covers the
Earths surface, the surrounding atmosphere, and all biomes!
