What Do You Know About The Ecdysozoa? Trivia Quiz - Quiz

The Ecdysozoa consist of one of the major categories within the animal kingdom, and it's likewise the largest since it comprises both the arthropods (spiders, crustaceans, and insects) and the nematodes. How well do you think you know Ecdysozoa? Take this quiz to examine yourself.

Questions and Answers

1.

What is an Ecdysozoa?
- A.
  
  A specie
- B.
  
  A superphylum
- C.
  
  A genus
- D.
  
  A phyla
Correct Answer
B. A superpHylum

Explanation
Ecdysozoa is a superphylum, which is a higher taxonomic rank above phylum. Superphylum is used to classify groups of organisms that share certain characteristics and are more closely related to each other than to organisms in other phyla. Ecdysozoa includes a diverse group of animals that undergo molting, such as arthropods (insects, spiders, crustaceans) and nematodes (roundworms). This classification helps scientists understand the evolutionary relationships and diversity within the animal kingdom.

What is referred as an Ecdysozoa?
- A.
  
  Arthropoda
- B.
  
  Nematoda
- C.
  
  Tardigrada
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Ecdysozoa is a superphylum that includes three major phyla: Arthropoda, Nematoda, and Tardigrada. These phyla share a common characteristic, which is the ability to undergo ecdysis, or molting. Arthropoda includes insects, spiders, and crustaceans, while Nematoda refers to roundworms, and Tardigrada includes water bears. Therefore, the correct answer is "All of the above" because all three phyla are considered part of the Ecdysozoa superphylum.

  Myriapoda
- B.
  
  Pauropoda

  Chilopoda
Correct Answer
C. Cycloneuralia

Explanation
Cycloneuralia is another name for Ecdysozoa.

4.

Which of the following is the morphological feature of the Ecdysozoa?
- A.
  
  Shedding of exoskeleton
- B.
  
  Being asymetrical
- C.
  
  Being small
- D.
  
  Making cocoons
Correct Answer
A. Shedding of exoskeleton

Explanation
The correct answer is shedding of exoskeleton. Ecdysozoa is a superphylum of invertebrates that includes organisms such as insects and crustaceans. One of the defining characteristics of this group is their ability to shed their exoskeleton, a process known as ecdysis or molting. This allows them to grow and develop throughout their lifespan.

Which of the following creatures is an Ecdysozoa?
- A.
  
  Water bear
- B.
  
  Spider
- C.
  
  Crab
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
All of the above creatures are Ecdysozoa. Ecdysozoa is a superphylum of invertebrates that includes organisms that undergo ecdysis, which is the process of shedding their exoskeleton or outer covering. Water bears, spiders, and crabs are all examples of organisms that belong to this group. They all go through molting or shedding of their exoskeleton as they grow. Therefore, the correct answer is All of the above.

Ecdysozoa is considered as:
- A.
  
  A clade
- B.
  
  A group
- C.
  
  A swarm
- D.
  
  None of these
Correct Answer
A. A clade

Explanation
Ecdysozoa is considered as a clade because it refers to a group of animals that share a common ancestor and have a unique characteristic of molting or shedding their exoskeletons. This clade includes various phyla such as arthropods, nematodes, and tardigrades, among others. The term "clade" is used in biology to describe a group of organisms that includes an ancestor and all of its descendants. Therefore, Ecdysozoa being a clade signifies its evolutionary relationship and shared characteristics among its members.

Ecdysozoa comprise of how many phyla?
- A.
  
  6
- B.
  
  7
- C.
  
  8
- D.
  
  9
Correct Answer
C. 8

Explanation
Ecdysozoa is a superphylum that includes a diverse group of invertebrate animals, such as arthropods and nematodes. This superphylum is known to consist of eight different phyla, which makes the correct answer to the question "8".

Which of the following creatures isn't an Ecdysozoa?
- A.
  
  Frog
- B.
  
  Butterfly
- C.
  
  Lobster
- D.
  
  Velvet worm
Correct Answer
A. Frog

Explanation
The correct answer is Frog because frogs belong to the phylum Chordata, not Ecdysozoa. Ecdysozoa is a group of invertebrates that undergo molting, while frogs are vertebrates with a backbone.

Ecdysozoa has how many germ layers?
- A.
  
  1
- B.
  
  2
- C.
  
  3
- D.
  
  4
Correct Answer
C. 3

Explanation
Ecdysozoa is a superphylum that includes animals with three germ layers. Germ layers are the primary layers of cells in the early embryo that give rise to different tissues and organs. In animals, there are typically three germ layers: the ectoderm, mesoderm, and endoderm. The ectoderm forms the outer layer, the mesoderm forms the middle layer, and the endoderm forms the inner layer. Therefore, Ecdysozoa, being a part of the animal kingdom, also has three germ layers.

Which of the following creatures is almost similar to Ecdysozoa?
- A.
  
  Chelicerata
- B.
  
  Mollusca
- C.
  
  Annelida
- D.
  
  Lophotrochozoa
Correct Answer
D. LopHotrochozoa

Explanation
Lophotrochozoa is a superphylum of animals that includes various phyla such as Annelida (segmented worms) and Mollusca (snails, clams, and squid). Ecdysozoa is another superphylum that includes phyla such as Arthropoda (insects, spiders, and crustaceans) and Chelicerata (spiders, scorpions, and horseshoe crabs). While Chelicerata is a phylum within Ecdysozoa, Lophotrochozoa encompasses other phyla that are not closely related to Ecdysozoa. Therefore, Lophotrochozoa is almost similar to Ecdysozoa in terms of being a superphylum, but it includes different phyla.
