What are four ways arthropods obtain food?

You have to be more specific to which arthropod you are researching. There are many classifications: insects, arachnids, crustaceans, etc. Some Spiders weave webs while others go out in search of food. Crabs, lobsters, and shrimps scavenge. Bees go around and outward from their hive in a circular motion in search of flowers.
