Answer 1

Hint: Entomology is related to the largest phylum of Chordata. This is the study of insects and their relationship to humans, the environment, and the other organisms.

Complete answer:
Entomology is the study of various aspects of insects. The term insect is taken from the Latin word insectum. They are hexapod invertebrate members of the largest class of the phylum Arthropoda e.g cockroach, mosquito, butterfly, housefly, grasshopper, ladybird, etc.

Additional Information: The body of insects have segments, they have jointed legs and an external skeleton. From other arthropods, insects can be differentiated based on their body construction. The body of an insect is divided into three major regions:
1)The head- It bears the mouthparts, eyes, and a pair of antennae.
2)The thorax- It bears three segments which usually has three pairs of legs in adults (that is why Hexapod) and also bears one or two pairs of wings.
3)The abdomen- This region also has many segments. It bears the digestive organs, excretory organs, and reproductive organs.

-Entomology is very helpful for mankind by detecting the role of insects in spreading diseases.
-Also in discovering different ways of protecting food and fiber crops and different livestock from being damaged.
-It also informs us about how some insects are beneficial and are contributing to the well-being of humans, animals, and plants.
So, the correct answer is,” various aspects of insects".

Note: -Insects are also used as quality indicators of the environment to assess water quality and soil contamination
-Entomology enables us about the abilities of insects for becoming the basis of many studies related to biodiversity.
-Through entomology, we came to know that many insects are responsible to pollinate plants, produce useful substances, control pest insects, act as scavengers, and serve as food for other animals.
