Write a hypothesis about the addition of compost (nutrients) to the soil and ecological succession using this format: “if . . then . . because . .” be sure to answer the lab question, “how does the presence of additional nutrients affect the process of succession? ”

Hypothesis is a proposed mechanism / way for a scientific phenomenon or observation.

As given that we are adding nutrients in the form of compost to the soil, this will definitely enhance the growth of the plants as nutrients are essential for plant growth

so the hypothesis can be drafted or stated as

If we add nutrients to the soil as compost, the plants will show a better growth (in every aspect), the process of succession of growth will get enhanced due to presence of more fertile and nutrient rich soil.

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.
