  types of competition  resource competition (ÀÚ¿ø °æÀï)  
occurs when a number of organisms utilize common resources that are in short supply
interference competition (°£¼· °æÀï)  
occurs when the organisms seeking a resource harm one another in the process, even if the resource is not in short supply
  types of competition  scramble competition (ºÒ¿ÏÀü °æÀï)  all individuals are equally affected  there are no ¡°winners¡± or ¡°losers¡±  contest competition (¿ÏÀü°æÀï)  
some individuals acquire resources at the expense of other individuals
there are ¡°winners¡± and ¡°losers¡±    types of competition  intra-specific competition (Á¾³» °æÀï)  between members of the same species  inters-specific competition (Á¾°£ °æÀï)  between two or more different species    the kinds of resources  for plants  light, nutrients, water µî  pollinators, space µî  for animals  water, foods, mate µî  
spaces : nesting site, wintering site, resting site µî
  theories on competition for resources  lotka-volterra model  
describe competition between organisms for food or space, are based on the logistic curve
species 1  dn1/dt r1n1((k1-n1)/k1)  species 2  dn2/dt r2n2((k2-n2)/k2)    lotka-volterra model  
two competitors don¡¯t use the same amount of resource
¥án2 : equivalent number of species 1 individuals
¥ân1 : equivalent number of species 2 individuals
