01.01 HC) Food web starting with sun and pointing to grasshopper and squirrel; Grasshopper pointing to squirrel, wolf, and snake; squirrel pointing to wolf, snake, and bird; wolf pointing to decomposition with worms and mushrooms; snake pointing to wolf and decomposition with worms and mushrooms; bird pointing to decomposition with worms and mushrooms; decomposition pointing to the sun stating soil nutrients. If we removed the wolf, snake, and hawk from this food web, what best explains the impact it would have? The number of producers would increase. The number of decomposers would increase. The number of primary consumers would increase. The numbers of primary consumers would decrease.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
