Describe the harmful effects and benefits of arthropods
Answers
Required Answer:-
Harmful effects of arthropods:
- A few species of arthropods are harmful to humans because they are transmitter of viruses and bacteria which causes diseases.
- Most of the species of arthropods harm the plants planted in the gardens or farms.
- Some of the arthropods can harm humans by injecting stringers which contains poison and it can be harmful for humans.
Benefits of arthropods:
- Some species of arthropods are useful for controlling the weeds growth. Weeds are the unwanted plants grows mainly in farms and gardens.
- Some species of the arthropods prevent pest problems.
- Some are beneficial for the pollination of crops because many food crops are pollinated by arthropods.
☯ Correct Question ☯
Describe the harmful effects and benefits of arthropods
☯ Concept ☯
Arthropods are invertebrate (without a backbone) animals of the phylum Arthropoda that have a segmented body, jointed legs, and a tough outer covering or exoskeleton.
☯ Characteristics ☯
>The bodies of arthropods are divided into different segments, each having a specialized role.
>The exoskeleton acts as a protective covering to the underlying segmented body.
>The cuticle acts as a hinge between segments, allowing the body to bend and move to the right or left.
>Arthropods usually have more than one pair of eyes, which may include both simple and compound pairs. (A compound eye is made up of many separate units for receiving light, each with its own lens.) Breathing in land-arthropods is usually accomplished through air tubes called tracheae.
☯ Benifits ☯
> Arthropods are of ecological importance because of their sheer numbers and extreme diversity.
>More than 874,000 living species of arthropods have been identified, making up more than 80 percent of all named species of animals.
>However, it is estimated that many more thousands of arthropods exist that have not yet been named.
>Most of these unnamed species are small beetles and other insects, and most of these occur in old-growth tropical rain forests—areas that have not yet been well explored.
☯ Harmful effect ☯
>Arthropods are both harmful and helpful to humans.
>A few species are transmitters of bacteria or viruses that cause diseases such as malaria, yellow fever, encephalitis, and Lyme disease.
>Scorpions, some spiders, and bees and wasps have poison glands and can hurt or even (though rarely) kill people by injecting poison through stingers.
>Some arthropods are a nutritious source of food in many parts of the world, and insects play an important role in pollination (a process necessary for production in many plants).
