I need a fresh answer that’s not already used.

Explanation:

The First wave of Immigration to the U.S. were mostly White, Protestant Europeans from Germany and England. The second wave of Immigration to the U.S. consisted of immigrants fleeing Eastern European and Mediterranean countries because of either religious reasons or economic reasons, this group of immigrants faced discrimination in the U.S. The third wave of immigration to the U.S. mainly consists of immigrants from Latin America and Eastern Asia. Immigration from Latin America has accelerated in the past 40 years due to decades of corruption and war that has been caused by American intervention in the region during the 70s and 80s.

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
