Insects are the largest group of animals on Earth. Insect diversity is greatest in the tropics, where habitat destruction and species extinction are occurring at an alarming rate. What biological, economic, and ethical arguments can you advance to persuade people and governments to preserve this biological diversity?
To discuss:
The biological, economic, and ethical aspects regarding the preservation of insects.
Introduction:
The insects are included in the arthropods. The insects have an exoskeleton made up of chitin, three pairs of legs, and a segmented body. The insects are a major part of the ecosystem.
Explanation of Solution
All the living organisms are interdependent for their survival. The richness of plants and animals in a distinct habitat determines the biodiversity of that region. The services offered by nature reduced by the loss of biodiversity.
Biological importance:
One of the efficient methods of pollination is insect-pollination. The insects, such as bees and flies transfer the pollen grains to the other flowers of the same or different plants. This leads to the increase in pollination, thus benefiting the plants. The bees and flies attracted to the flowers for the nectar produced by the flowers. Some of the insects are decomposers and help in maintaining the richness of soil and aerate the soil by digging holes as their homes.
Economic importance:
Some of the insects are highly valuable in terms of products that are obtained from them. The silk, lacquer, wax, and honey is obtained and they are economical to humans.
Ethical importance:
Diseases developed by the microbes transmitted by insects every year affect the humans. The insects should be preserved even if insects are harming humans because every life form is important for the continuation of life on Earth. Any sort of disturbance in levels of life forms will affect all the life forms.
The insects are important in terms of economic, biological, and ethical aspects because the balance of all life forms is necessary for the well functioning of the life cycle of all organisms on this planet.

What are the advantages over livestock?arrow_forwardWhat are some potential solutions to decrease the threat/endangerment of sea turtles? What can humans do? What are some solutions that scientist or convervationist tried to do to help sea turtles? What is one hypothesis on further environmental, ecological, biodiversity or other biological problems that this solution might intentionally or unintentionally create?arrow_forwardChoose all incorrect statement. In 2021, 23 species were declared extinct. Most of these have been presumed to be extinct for decades. Eight of the declared extinctions were bird species endemic to the Hawaiian Islands. One species declared extinct was the Molokai creeper (pictured). Main causes of their extinction include loss of suitable habitat, disease, and predation by introduced mongooses and rats. Avian malaria is transmitted between bird species in Hawaii by mosquitoes that were brought to the islands by ships many decades ago. Which of the following statements is NOT accurate? a.Avian malaria is a vector-borne disease; if it infects 90% of the birds regardless of bird population size, it is acting as a density-independent factor. b.Among vertebrates, bird population sizes have declined the most compared to any other vertebrate group. c.Eliminating invasive rats and mongooses from the Hawaiian Islands, like goats were eliminated from the Galapagos, could help prevent further…arrow_forward

Essentially, if Totoaba went extinct, what would happen? *This question is being asked for personal knowledge, not for any school assignments!arrow_forwardWhich of the following is a Monotreme? a. kangaroo b. koala c. bandicoot d. platypusarrow_forwardWhy are frogs a good indicator species? They are increasing in number, suggesting that they are resistant to environmental degradation. They are resistant to increases in ultraviolet light. They are of considerable economic importance. Their numbers can be manipulated easily with minimal effects on other species. Their eggs do not have hard shells to protect them from environmental contaminants.arrow_forward
- The International Union for the Conservation of Nature and Natural Resources (IUCN), has declared 418 animal species in the Philippines to threatened: meaning they are either vulnerable, endangered, or critically endangered. What small steps that you can do to save these animals?arrow_forwardWhat is the difference between a K-strategist and an r-strategist? K-strategists and r-strategists differ in the longevity of life and the number of offspring. K-strategists have a longer life span but produce fewer offspring, and r-strategists have a shorter life span but produce more offspring. K-strategists are species whose generations consist of short-lived organisms that produce no offspring, and r-strategists are species whose generations consist of short-lived organisms that produce few offspring. K-strategists are species whose generations consist of long-lived organisms that produce many offspring, and r-strategists are species whose generations consist of short-lived organisms that produce few offspring. R-strategists are species whose generations consist of long-lived organisms that produce few offspring. In contrast, K-strategists are species whose generations consist of…arrow_forwardA group of researchers are interested in whether temperature has an affect on time to metamorphosis in a species of frog.
