Warm Up: Answer the following questions Where do we get our energy? If you were to make a contribution to humanity what would it be? Would you be an organ donor? Why or Why not? How do you want to be buried? What happens to your physical body when you die? Write on the “Before I Die…” wall

Objective of the day Analyze the flow of matter and energy through trophic levels in an ecosystem.

Statement of Inquiry/IB Trait All living beings are interdependent and this interdependence and interaction creates different ecosystems where a change in one component creates a change in the entire system IB TRAIT: KNOWLEDGEABLE, COMMUNICATORS and INQUIRERS

Trophic Levels Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem.

Trophic Levels Biomass- the amount of organic matter comprising a group of organisms in a habitat. As you move up a food chain, both available energy and biomass decrease. Energy is transferred upwards but is diminished with each transfer.

E N R G Y Trophic Levels Producers- Autotrophs Tertiary consumers- top carnivores Secondary consumers-small carnivores Primary consumers- Herbivores Producers- Autotrophs

Trophic Levels Food chain- simple model that shows how matter and energy move through an ecosystem

Trophic Levels Food web- shows all possible feeding relationships in a community at each trophic level Represents a network of interconnected food chains

Food chain Food web (just 1 path of energy) (all possible energy paths)
