Document Summary

Functional diversity: adaptations of organisms to their environment. Functional diversity: acquiring resources, defence against predators, life histories and reproduction, acquiring resources. Trade off: the relationship between the benefit of a trait in one context and its cost in another context (in order to acquire resources in a specific niche, organisms maximize one traits at the expense of another. ) Principle of allocation - all life functions cannot be simultaneously maximized (this causes diversity because each species develop different traits at the expense of some other) C,h,o - make up an organism"s biomass. N,p - make up the bulk of an organism"s metabolic machinery. Water - the medium in which biological reaction occurs. What are the 2 fundamental ways in which energy and resources are acquired: autotrophs: live exclusively on inorganic sources of carbon, nitrogen, and other essential resources, photoautotrophs: use energy from sunlight to power metabolism, growth, and resource-getting i.
