asap : )

Correct answer choice is :

A) Type of wetland

Explanation:

Wetlands, as determined by the Convention on Wetlands of International Significance, cover lakes and rivers, bogs and swamps, wet meadows and peat lands, havens, bays, deltas and tidal flats, near-shore aquatic zones, mangroves and coral beaches, and human-made places such as fish pools, rice paddies, lakes, and salt pots. Wetland ecosystems endure a vital part of Europe’s biodiversity.

The correct answer is option a, that is, type of wetland.  

The factor, which is the least influential in affecting the biodiversity of wetlands is the type of wetland. In spite of its kind, there will still be a lot of fauna and flora in a certain wetland. Other factors like nutrients, food resources, and whether there is adequate water or not are far more essential for the existence of biodiversity than the type of wetlands.
