There is a source of usable energy. There are nutrient cycles going on. There are processors that are producing energy in a loop. Producers falls apart with use. Performance of individual organisms: time co-acting response higher X level that higher X level that begins to initiate begins to initiate a response a response counter-acting counter-acting lower X level that response responselower X level that begins to initiate begins to initiate a response a response time involves coacting responses. co-acting response X levels lower X level that lower X level that begins to initiate begins to initiate a response a response Survival = individual organism Persistence = something lasting across generations higher X level that higher X level that begins to initiate begins to initiate a response a response lower X level that lower X level that begins to initiate begins to initiate a response a response time time time Coacting: Organism detects something, but trend is changing and it acts to accelerate or maintain that trend. X levels X levels X levels higher X level that higher X level that begins to initiate begins to initiate a response counter-acting counter-acting response a response response time Reproduction X levels involves counteracting responses. X levels X levels Maintain levels of stuff, structure, etc. Maintain: If some thing gets too high/low, there must be (a) detectors and (b) something to bring it back to normal. X levels Survival higher X level that higher X level that begins to initiate begins to initiate a response a response co-acting response co-acting response lower X level that lower X level that begins to initiate begins to initiate a response a response time time Examples of coacting: attraction taking over your life, everything associated with reproduction, growth/development, pregnancy, ovulation Reproduce faster than your demise so you can persist. 3-6 Check Your Understanding: 1. Describe some real-life scenarios for each individual performance design. 2. Make sure you understand the dichotomy between survival and reproduction and describe some different strategies that organisms have solved this dichotomy. Life’s performance hierarchy: ecosystems geochemical processes biological communities species (populations) multicellular organisms single-celled organisms organ systems organs tissues eukaryotic cells prokaryotic cells subcellular processes 3-7...
