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?



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

With a partner, generate a list of things that
all living things must have for survival.

The non-living parts of the environment
The upper and lower limits in which an

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


Habitat: the organism’s address; where does
it live?
Ex. A moose’s habitat is the boreal forest.

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 provides
food for coyotes.
