Activation energy is the amount of energy required to initiate a chemical reaction. The activation energy can be determined from reaction rate constants at different temperatures by the equation. ln(k 2 /k 1) = E a /R x (1/T 1 - 1/T 2).
Robins also eat other small insects, berries, fallen fruits, and especially Rosaceae fruit in the fall and winter. Robins cannot digest hard fruits or grains, so they stick to soft fruits and organisms with softer skeletons (Howell, 1942). http://www.bio.davidson.edu/people/vecas...
Common Buzzard Diet. Common Buzzards feed mainly on Rabbits but will take just about any small mammal, reptile and often carrion (the carcass of a dead animal). The birds can occasionally be seen standing proudly on a piece of road kill defending it whilst they eat.
