What is an Ecosystem?
What is an ecosystem? How many different types of ecosystems can
you identify? How do the abiotic and biotic parts of an
ecosystem differ? In what different ways do living and non-living
things interact in ecosystems? How do food, energy, and nutrients move
through an ecosystem? In what ways do natural events and human
activities cause changes in ecosystems?
Brainstorm
Can be described by the types of organisms and the conditions found there.
Include abiotic (non-living) and biotic (living) things.
Can be large or small
Ecosystems
With a partner, generate a list of things that all living things must have for survival.
What do living things need for survival?
Ocean Forest Pond Arctic What others can you think of?

The non-living parts of the environment The upper and lower limits in which an
organism can survive is called the organism’s range of tolerance
Examples (Make notes on each p.16 -17)◦ Intensity of sunlight◦ Temperature◦ Soil◦ Air and wind◦ Water
The Abiotic Environment

The living parts of the environment Includes MANY species of organisms Species
◦ A group of organisms that can reproduce to produce similar, fertile organisms
The Biotic Environment

Ecosystem
Levels of Organization
Habitat: the organism’s address; where does it live?
Ex. A moose’s habitat is the boreal forest.
Habitat vs. Niche
Niche: the organism’s job; what role does the organism play in its environment. It includes:◦ where it lives◦ how it obtains food◦ how it affects its environment
Ex. A moose lives in the boreal forest, it is a herbivore (plant eater), it provides a home for parasites and it providesfood for coyotes.
