Summary Introduction

Concept introduction: Kingdom: Animalia includes all animals. Animals are multicellular, heterotrophic organisms. They obtain nutrients by decomposing organic materials or by ingesting other organisms. All organisms are motile. Sexual reproduction occurs in almost all animals.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: Insects animal groups are the most abundant in number of individuals and number of species. Hence, option a. is the correct answer.

Explanation of Solution

Reasons for correct statement:

Option a. is given as, “insects”. The most abundant species are found to be insects. There are about 205 million species of insects identified by zoologistsPhylum: Arthropoda has about 85% of total species in the animal kingdom. In Phylum: Arthropoda, about 75% are insects. Thus, the most abundant individuals in animal kingdom are found to be insects. Hence, option a. is the correct answer.

Reasons for incorrect statement:

Option b. is given as, “birds”. The number of bird’s species is around 10,000. When compared to birds, the number of insects is about 2.5 million which are the most abundant in the world. Hence, option b. is incorrect.

Option c. is given as, “protists”. The number of protists’s species is around 200,000. When compared to protists, the number of insects is about 2.5 million which are the most abundant in the world. Hence, option c. is incorrect.

Option d. is given as, “mammals”. The number of mammal species is around 5,416. When compared to mammals, the number of insects is about 2.5 million which are the most abundant in the world. Hence, option d. is incorrect.

Hence, options b., c., and d. are incorrect.

Conclusion

Conclusion: Insects are the most abundant species in the world.
