In the 1950s and 1960s, many behaviorists believed that biology played little influence in how organisms could be conditioned. describe the rat studies of john garcia, and how the findings challenged the beliefs of strict behaviorists

John Garcia provided one type of stimulus of sight, taste and sight to the rats. This process is called neutral stimulation. After several months he exposed the rats with different drugs and different type of radiation. He named these stimuli as unconditional stimuli. Due to this treatment rats became sick.  

Through this experiment he discovered that if rates provide with new stimuli different than neutral stimuli, they may become sick but after recovery from nuisance they started avoiding that unconditional stimuli.

These results challenged the belief of strict behaviorists that unconditional stimuli play little influence in how organisms could be conditioned.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle
