Chapters 3,4 & 6
*Turn to your partner and describe an “interaction” between two organisms.
Now describe an example of an organism “interacting” with its environment.
4. Communities- several populations in the same area (ex. Different herds/packs in the same state).
5. Ecosystem-all of the organisms that live in a specific place along with all of their physical (nonliving) environment.
6. Biome- a group of ecosystems that have the same climate and similar organisms.
*Can you think of some examples of biomes?
Why do you think producers always come first?
How could water cycle in this way? Write down an example.
How do organisms acquire energy from carbohydrates?
Competition, predation, symbiosis, mutualism, commensalism and parasitism.
3. Symbiosis- two species live closely together.
a. mutualism- both species benefit from the relationship.
b. commensalism- one member benefits the other is not helped or harmed.
c. Parasitism- one organism lives on or inside the other and harms it.
Why do we need a variety of organisms on Earth?
Human activity can reduce biodiversity by:
Give an example of each-
b. Hunting to extinction
d. Introduced species
What can we do to protect biodiversity?
Strategies for Conservation:
So what if it gets warmer, I like summer!
Partner up and brainstorm 3 ways that humans can
