Complete answer-
It is the largest class of animals including more than 750,000 species. They live on land and in the air. Many have become secondarily aquatic. They are very numerous – roughly one billion insects for every human being. They are the most successful land invertebrate and the only competition with humans for dominance. They are living organisms and need water for the metabolism of their body. The body of insects is divided into 3 regions – head, thorax and abdomen.
Yes, insects also live without water. The different types of insects and based on their features of body and habitat, the water requirements vary. Wild insects which fulfill their water requirement by the help of food they feed on. Some insects are cold-blooded which can live without water for a longer time period. Cockroaches can also survive without water. Ants and Spiders need water on a daily basis. Some plant-eating insects get the water from their food and fulfill their requirements.
