It would definitely be methane
The tropical rain forests are the places on the land that have by far the highest biodiversity, both in plant and animal life. Because they have such a high biodiversity, and the vegetation is evergreen and constantly active, they have a huge effect on the global biosphere. They're the ones that increase the numbers and diversity on the planet, but also that huge biodiversity, especially in the plant life, contributes to higher levels of oxygen into the atmosphere, and that is very beneficial for all of the biodiversity on the planet. It is not coincidence that the Amazon rain forest, the largest in the present, is nicknamed ''the lungs of the Earth''.
Answer:
Option (C)
Explanation:
A barrier island is usually defined as a long and narrow type of land that is dominantly comprised of sand particles and are oriented parallel to the coastal mainland.
The presence of a barrier island protects the coastal rocks from getting eroded by the strong water waves, wind, and tidal effects. This acts as a barrier and there lies a lagoon between the coastal landform and the barrier island.
It plays an important role in the ecosystem as it provides valuable nutrients and minerals, supporting a large number of living species.
Thus, the correct answer is option (C).
It is using crops and plants origins to create fuel for vehicles.
