question 2
how do humans accumulate microplastics inside their bodies from the ocean?

Explanation:

Question 1: Fringing reefs form directly along the shore of an island. Barrier reefs are separated from the island by a lagoon and are parallel to the shore. Atolls form when an island subsides and the reef continues to grow upwards, leaving a central lagoon.
Question 2: Humans accumulate microplastics from the ocean through ingestion of seafood that has consumed microplastics, inhalation of airborne microplastics that have originated from the ocean - atmosphere exchange, and through skin contact with water containing microplastics.

Answer:

Question 1: Fringing reefs are close to the island shore; barrier reefs are separated by a lagoon; atolls form as an island subsides with reef growing upwards.
Question 2: Through eating seafood, inhaling airborne micro - plastics, and skin contact with contaminated water.
