Building Plans of Organisms 1. Life: how is it classified? 1a. Life subdivided by function 1b. Life subdivided by family 2. Family relationships of Phyla

Life divided by function : Producers: (photosynthesis and chemosynthesis): make organic matter autotrophs. Consumers: use organic matter (heterotrophs). Decomposers: use organic matter, return constituents to environment (heterotrophs). H 2 O + CO 2 CH 2 O + O 2
