3.1 – What is Ecology?• Ecology = Scientific study of interactions among organisms
and between organisms and their environments.
• Web of interdependence

• Organism - an individual living thing • Ex) alligator, turtle, or egret.

Biosphere – the entire planet

Biodiversity• The assortment, or variety, of living things in an
ecosystem• Rain forests have more biodiversity than
other locations in the world, but are threatened by human activities.
Which biome has the greatest biodiversity?

• A keystone species is a species that has an unusually large effect on its ecosystem.

Why are they called a “Keystone” species?

Example of Keystone Species

Keystone Species• How might the mountain lion be a keystone
species?
• What about the honeybee?

Biotic & Abiotic Factors • Biotic factors – any living thing in an environment that an
organism might interact with.• Examples for a Bullfrog?
• Insects it eats. Lilly pads it rests on. Algae/aquatic plants it hides in. Birds that prey upon them.
• Abiotic factors – any nonliving part of the environment. Examples?• Sunlight, heat, precipitation, humidity, soil type,…
How do these factors influence in each other?

3.2 Producers & Consumers• Primary producers / Autotrophs –
• First producers of energy-rich compounds that are later used by other organisms
• Types of Primary Producers • Photosynthesis• Chemosynthesis (chemical energy used to
produce sugars)-Does not require light energy, found
in harsh environments!

Consumers• A.K.A - Heterotrophs• Rely on other organisms for energy and nutrients
