Question

Which ecosystem likely has the lowest species diversity?
grassland, coral reef, desert, tropical rainforest

Answer 1

Among the ecosystems listed, a **desert** is likely to have the lowest species diversity. While deserts can support a variety of specially adapted plants and animals, their harsh environmental conditions (extreme temperatures, low precipitation) limit the number of species that can thrive there. In contrast, ecosystems like grasslands, coral reefs, and tropical rainforests typically have much higher species diversity due to their more favorable conditions and complex ecological interactions. Coral reefs, in particular, are considered some of the most biodiverse ecosystems on the planet. Tropical rainforests also have exceptionally high species diversity, often regarded as one of the richest ecosystems in terms of species variety.
