Unformatted text preview: o Dependent-cramps o Theory: an explanation that can be highly supported to be true by supporting evidence.—NOT proven! Biology concepts: a. Life requires energy: i. Energy= the capacity to do work ii. Metabolism= cell reactions to acquire and use energy to grow, strive, and reproduce b. Interdependencies among organisms: i. Producers: make own food using external energy ii. Consumers: depend on energy stored in tissues of others iii. Decomposers: break down remains and wastes c. Energy flow: i. Can’t be used again ii. Sun iii. Organism to organism (only some passed on) iv. Energy flows in same direction v. Eventually, all energy flows back to the environment d. Six kingdoms Origin of life 1. Archaebacteria 2. Eukaryotes 3. Eubacteria...
