Question

question 7 2/10 in the florida mangrove swamp, what helps mangrove seeds to take root? salt water decomposing animals sandy bottom fresh water

Explanation:

Mangrove swamps in Florida have a sandy bottom which provides a suitable substrate for mangrove seeds to anchor and take root. Salt water is part of the mangrove ecosystem but not the direct factor for rooting; decomposing animals don't directly aid in seed rooting; fresh water is not the primary water type in mangrove swamps (they are adapted to salt - water or brackish conditions, but the sandy bottom is key for rooting).

Answer:

C. Sandy bottom
