So both the rabbits are Bb which means there will be a chart which comes out with one BB, Two Bb and one bb, For the rabbit to become brown fur it would need to get bb from theirs parents reproducing, if it's Bb they will just carry the trait recessive trait again and if it's BB they won't be carrying the trait
I believe it's the the decrease of owls and if i' wrong sorry
Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.
That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.
Hope it helped,
