BIO205H5 Chapter Notes - Chapter 8: Global Warming, Ectotherm, Indeterminate Growth
Document Summary
The life history of an organism is a list of its reproduction, survival, growth and development. Bio 205 chapter 8: traits associated with the life history is . Fecundity the number of offspring produced. Parity the number of occurrences of organism reproduction. Parental investment the amount of time the parent spends bringing up the offspring: an organism can have either a fast or slow life history. Fast the organism reaches sexual maturity fast, has a high fecundity, low parental investment and short life-spans. On average, an organism produces enough offspring to replace itself, since most of them die before reaching maturity. There are three extreme categories: stress, competition and the frequency of disturbances. The three types of plants that thrive within these extremes are stress tolerators, competitors and ruderals: plants that grow under stressful conditions such as under extreme temperatures. Ruderals invest most of their energy in seeds that can be easily dispersed (ex. weeds)
