For the first animal: 250x1000=250000 mg
for the second animal: 330x1000=330000 mg
to find the difference: 330000-250000=80000 mg (which is your final answer)
observations and questions; the corn plants grew fungi and when they were pout in shade the fungi died off the plant.
experiement: she put plants in the sun and some in shade to compare how the fungi grew differently.
