What is Ecology?
The study of interactions among
organisms and between organisms
and their environment.

Foundation of Environmental ScienceEcology: the study of
how living organisms interact with each other and their nonliving environment

Ecology studies how all of these living and nonliving things interact

All Ecosystems are connectedHow does your ecosystem impact the Atlantic Ocean?

Parts of an ecosystem

Parts of an ecosystem In order for an ecosystem to
survive it needs five basic components:
EnergyMineral NutrientsWaterOxygenLiving Organisms

If your are conducting a study of the interactions of vegetation, animals, mineral composition of the soil, and water levels in a saltmarsh. You are studying the saltmarsh ___.

Biotic and Abiotic FactorsBiotic: living & once living
parts of an ecosystemPlants, animals,
bacteria, dead organisms, wastes
Abiotic: nonliving parts of an ecosystem
Air, water, soil, sunlight, temperature

What are some biotic AND abiotic parts of this ecosystem?

Smallest UnitOrganism: an individual living thing like you, a tree, a fox, a rose
Species: groups of closely related organisms that can mate & produce fertile offspring like red foxes or black widow spiders, or grizzly bears

Species Species: groups of
organisms that resemble each other in appearance, behavior, chemistry and genetic makeup…able to reproduce
3.6 to 100 million species (1.4 identified)
Mostly insects/micro
Tropical forests

PopulationPopulation: all the members of the same species that live in the same place at the same timeField mice living in a corn
field, grizzly bears of Yellowstone Park
Members breed with one another, rather than with other populations

HabitatHabitats provide an organism with resources—anything an organism needs to survive and reproduce, including food, shelter, and mates
