The competitive exclusion principle is best defined as Group of answer choices the principle that two species that occupy the same niche cannot coexist indefinitely. the competition among individuals of the same species in the same location. an interaction between species that enhances the fitness of the exploiting individual while reducing the fitness of the exploited individual. the principle that if an organism allocates energy to one function, such as growth or reproduction, it reduces the amount of energy available to other functions.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
