Nine Phyla Of The Animal Kingdom Quiz!

The correct answer is sponges. Porifera is a phylum that includes sponges, which are multicellular organisms with specialized cells but no true tissues or organs. Coral, whales, and monkeys do not belong to the porifera phylum. Coral is a type of marine invertebrate belonging to the cnidaria phylum, while whales and monkeys are mammals belonging to the chordata phylum. Therefore, the correct answer is sponges.

Corals, jellyfish, anemones, and hydra belong to the phylum Cnideria. This phylum is characterized by the presence of specialized stinging cells called cnidocytes, which are used for capturing prey and defense. Cnideria organisms are also radially symmetrical and have a simple body structure. Examples of Cnideria include sea anemones, jellyfish, and corals.

The correct answer is flatworms. The Platyhelminthes phyla is a group of animals that includes flatworms. This phylum is characterized by their flattened body shape and lack of a body cavity. They can be found in various habitats such as freshwater, marine environments, and even as parasites in other animals. Some examples of flatworms include planarians, tapeworms, and flukes.

Insects have the largest number of organisms among the given categories in the Arthropods. Insects are a diverse group of arthropods, with over a million known species. They are found in almost every habitat on Earth and play important roles in pollination, decomposition, and as a food source for other animals. Their ability to adapt to various environments and their high reproductive rates contribute to their large population size, making them the category with the largest number of organisms in the Arthropods.

The correct answer is Earthworm. Earthworms are not classified as Nematoda because they belong to the phylum Annelida. Nematoda, on the other hand, is a separate phylum that includes worms like Trichina, Ringworm, and Hookworm. Earthworms have a segmented body and belong to a different group of worms compared to Nematoda.

Annelidas, such as earthworms, are known for their distinct characteristics, which include segmented bodies, having organs that are organized in the body, and passing soil through their digestive system. These characteristics are unique to annelidas and set them apart from other organisms.

Mollusks are classified into three categories: bivalves, gastropods, and cephalopods. Bivalves include organisms such as clams, mussels, scallops, and oysters. Gastropods consist of snails, slugs, conches, whelks, and periwinkles. Cephalopods comprise octopus and squid.

Amphibians are cold-blooded vertebrates that typically lay their eggs in water. They have moist skin that allows them to also breathe through their skin. While they do have lungs, they primarily obtain oxygen through their skin and the lining of their mouth. Therefore, the statement "They obtain oxygen through their lungs" is not a characteristic of amphibians.

The answer is 33 because the animal kingdom is classified into several phyla, which are major groups of animals with distinct characteristics. As of now, there are approximately 33 recognized phyla in the animal kingdom. These phyla include well-known groups such as Chordata (which includes mammals, birds, reptiles, etc.), Arthropoda (which includes insects, spiders, crustaceans, etc.), and Mollusca (which includes snails, clams, squids, etc.), among others.

All animals share the following characteristics:

Eukaryotic: Their cells have a nucleus.

Macroscopic: Most are visible to the naked eye (except for a few microscopic ones).

Multicellular: Animals are made of many cells.

Heterotrophic: They obtain energy by consuming other organisms (they don’t make their own food like plants).

This makes "eukaryotic, macroscopic, multicellular and heterotrophic" the most complete and accurate description of all animals.
