Invertebrates Of Animal Kingdom Questions and Answers
- 1.
Invertebrates
- A.
Don't need oxygen.
- B.
Don't eat food.
- C.
Don't have a heart.
- D.
Don't have a backbone.
Correct Answer
D. Don't have a backbone.Explanation
Invertebrates are animals that do not have a backbone. This characteristic sets them apart from vertebrates, which have a well-defined backbone or spinal column. Invertebrates include a wide range of organisms such as insects, worms, mollusks, and crustaceans. While invertebrates may still require oxygen, eat food, and have a heart, the absence of a backbone is a defining feature of this group.Rate this question:

Octopus is an example of
- A.
Water-dwelling invertebrate
- B.
Land-dwelling invertebrate
- C.
Heartless invertebrate
- D.
None of these
Correct Answer
A. Water-dwelling invertebrateExplanation
The octopus is an example of a water-dwelling invertebrate because it lives in the ocean and does not have a backbone. It belongs to a group of invertebrates called cephalopods, which also includes squids and cuttlefish. Octopuses have a soft body and are well-adapted for life in the water, with features such as tentacles for movement and capturing prey, as well as the ability to change color and shape to camouflage themselves.Rate this question:

Invertebrates have
- A.
4 legs
- B.
6 legs
- C.
8 legs
- D.
Different invertebrates have different numbers of legs.
Correct Answer
D. Different invertebrates have different numbers of legs.Explanation
Invertebrates are a diverse group of animals that do not have a backbone. They include insects, spiders, worms, and many other organisms. Unlike vertebrates, which typically have a fixed number of legs, invertebrates can have varying numbers of legs depending on their species. For example, insects generally have six legs, while spiders have eight legs. Therefore, it is accurate to say that different invertebrates have different numbers of legs.Rate this question:

Entoprocts may form colonies by _______.
- A.
Killing
- B.
Budding
- C.
Eating
- D.
None of these
Correct Answer
B. BuddingExplanation
Entoprocts may form colonies by budding. Budding is a form of asexual reproduction where a new individual develops as an outgrowth from the parent organism. In the case of entoprocts, individuals can reproduce by budding to form colonies of interconnected individuals. This allows them to increase their numbers and occupy a larger area. Budding is a common reproductive strategy in many organisms, including some types of plants and animals.Rate this question:

Invertebrates are considered helpful for farmers.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Invertebrates are considered helpful for farmers because they play important roles in pollination, decomposition, and pest control. Many invertebrates, such as bees and butterflies, are pollinators that help fertilize plants, leading to increased crop yields. Additionally, invertebrates like earthworms help break down organic matter, improving soil fertility. Some invertebrates also prey on pests, acting as natural pest control agents. Therefore, having a diverse population of invertebrates in agricultural ecosystems can benefit farmers by promoting healthy plant growth and reducing the need for synthetic pesticides.Rate this question:

The worm is an invertebrate with ______ legs.
- A.
2 legs
- B.
6 legs
- C.
8 legs
- D.
No legs
Correct Answer
D. No legsExplanation
The correct answer is "No legs" because worms are invertebrates that belong to the phylum Annelida, which includes organisms without legs. Instead of legs, worms have a long, cylindrical body that allows them to move through the soil or water by contracting and expanding their muscles. This adaptation enables them to burrow and navigate their environment without the need for legs.Rate this question:

Which animal is an invertebrate?
- A.
Peacock
- B.
Crab
- C.
Whale
- D.
Crocodile
Correct Answer
B. CrabExplanation
The correct answer is Crab because crabs are invertebrates, meaning they do not have a backbone or spinal column. They belong to a group of animals called arthropods, which also includes insects and spiders. In contrast, peacocks, whales, and crocodiles are all vertebrates, as they have a backbone.Rate this question:

Which of these is an invertebrate?
- A.
Snake
- B.
Human
- C.
Lobster
- D.
Elephant
Correct Answer
C. LobsterExplanation
A lobster is an invertebrate because it does not have a backbone or a spinal column. Invertebrates are animals that lack a vertebral column, and they make up the majority of animal species on Earth. Lobsters belong to the phylum Arthropoda, which includes animals with jointed appendages and an exoskeleton. They are characterized by their hard external shell, segmented body, and multiple pairs of legs. Unlike snakes, humans, and elephants, which are all vertebrates, lobsters do not possess a backbone and therefore fall into the category of invertebrates.Rate this question:

Invertebrates are less in numbers compared to vertebrates.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because invertebrates are actually more numerous than vertebrates. Invertebrates make up about 97% of all animal species on Earth, while vertebrates only make up about 3%. This is because invertebrates include a wide range of animals such as insects, worms, mollusks, and crustaceans, which have evolved and diversified into numerous species over millions of years. Vertebrates, on the other hand, include animals with a backbone, such as mammals, birds, reptiles, amphibians, and fish, which are relatively fewer in number compared to the vast array of invertebrates.Rate this question:

Which of these species is not an invertebrate?
- A.
Birds
- B.
Flatworms
- C.
Arthropods
- D.
Sponges
Correct Answer
A. BirdsExplanation
Birds are not invertebrates because they have a backbone, or a vertebral column. Invertebrates, on the other hand, do not have a backbone and include animals such as flatworms, arthropods, and sponges.Rate this question:
