Question:

The largest and the second largest phylum of the animal kingdom are

Options:

1. Arthropoda and Echinodermata
2. Echinodermata and Mollusca
3. Mollusca and vertebrata
4. Arthropoda and Mollusca

Solution:

Arthropoda, which includes animals such as insects, crustaceans, and arachnids, is the largest phylum in the animal kingdom in terms of the number of species and individuals. Mollusca, which includes animals such as snails, clams, and squids, is the second largest phylum in the animal kingdom. Echinodermata, which includes animals such as starfish, sea urchins, and sea cucumbers, is a phylum that is smaller in terms of species diversity compared to Arthropoda and Mollusca. Vertebrata, which includes animals with a backbone such as fish, mammals, birds, reptiles, and amphibians, is a subphylum within the phylum Chordata and is not one of the largest phyla in terms of species diversity.
