Slide 1 - EcologyIs the study of

Living Things (Biotic Factors) and their Environment (Abiotic Factors)

Slide 2 - Ecology Research

People who study Ecology are Ecologist!

Quantitative Descriptive

Measurements Observations

Slide 3 - Biotic FactorsAll the living organisms in an

environment!

All organisms are affected by the others that they live around!

Slide 4 - Abiotic FactorsThe non-living parts of an organism’s

environment.

(e.g. temp, light, moisture, soil).

Group A Group BSlide 5

Slide 6 - PopulationWhen there’s more than one organism of

the same species in an area.

Slide 7- CommunityAll the different species in an area.

No species is ever by itself!

Slide 8Biological Community Cont.

A change in one population can affect another population!

Slide 9 - Ecosystem Community and the non-living environment

ORBiotic Factors + Abiotic Factors

Slide 10 – BiomesAll the ecosystems on Earth that have similar climates and

organisms.

Aquatic Biomes(Water)

Terrestrial Biomes(Land)

Slide 11 – ClimateLatitude determines temperature!

As you move from the equator to the poles, temperatures get colder!

Degrees Zone

0° - 30° Warmest

30° - 60° Cooler

60 - 90° Coldest

Slide 12 - Aquatic BiomesApproximately 75% of Earth’s surface if water.Both contain salt, but salt water has more than

freshwater!

Salt Water Biomes

Oceans

Seas

Some Inland Lakes (e.g. Salt Lake)

Freshwater Biomes

Rivers

Streams

Ponds

Most lakes

Slide 13 - OceanLayers of the ocean support different

organisms.More organisms found at the surface of water.

Photic Zone = Receives sunlight

Aphotic zone = No Light.

Slide 14 - PlanktonOrganisms that live on the surface where there’s

light.They are the main source of

food for other marine organisms.

Slide 15 - RiversAll rivers flow into the ocean.

Estuary Place where rivers and oceans connect.

Gets saltier as you get move closer from river to ocean.

Slide 16Terrestrial (Land) Biomes

Biome Location ClimateTemperature +

Rainfall

Tundra 75 – 90 (Poles) Extremely Cold + Dry

Taiga 60 - 75 Very Cold + Dry

Temperature Rain Forest

30 – 60 (Middle) Average Temp + Wet

Desert 20 - 30 Hot + Dry

Tropical Rain Forest 0 – 20 (Equator) Hot + Wet

Slide 17 - Types of TreesGrouped based on types of leaves!

Conifer Deciduous

Slide 18 - Tree QuestionTree A Tree B

Slide 19 - PolesGround is always frozen (Permafrost).Plants need to put their roots in the ground.

No trees because they have no place to put their roots.

Slide 20 - Types of OrganismsEach Biome supports different organisms.

Biome Plants AnimalsTundra (Poles) No trees! Only small

plantsPolar Bears

Taiga (Alaska) Conifer Trees Brown Bears

Temp Rain Forest (Oregon)

Deciduous Trees Deer

Desert (Arizona) Cactus Lizards

Tropical Rain Forest (Hawaii)

Tropical Plants Tropical Fish

Slide 21 - Tropical Rain Forests

The forests have 3 layers.

Layer Name

Top Canopy

Middle Understory

Bottom Ground

Slide 22 - BiodiversityThe amount of different species in an area.

Rain Forests have the greatest biodiversity!

Slide 23 - BiosphereThe portion of Earth that supports life.

Slide 24 - Biosphere Cont.

All places one Earth where life is found. The Biosphere is not very big compared to Earth’s size.

Slide 25Levels of

Organization Summary

Slide 26 - HabitatThe place where an organism lives out its life.

Slide 27 - NicheWhat an organism uses for food and

shelter.

Slide 28 - SymbiosisWhen two organisms live close together!

Symbiosis Who benefits and is hurt?

Examples

Mutualism Both Species Benefit Humans + Intestinal Bacteria

Commensalism None benefits or is hurt Tree + Moss

Parasitism One benefits, other hurt Flea + Chunk
