Answer: 1.What is the differences between an arachnid and an insect-The body of an arachnid is comprised of two segments: the cephalothorax and abdomen. Insects have six legs; arachnids have eight legs. Insects have compound eyes; arachnids have simple eyes. Insects have antennae; arachnids do not
2.What is the role of arachnids in the ecosystem-Arachnids like spiders play an important role in their communities by regulating the density of other invertebrate herbivores and predators. Spiders that prey on mosquitoes directly lower the numbers of these pests, and can help reduce the spread of mosquito-borne disease.
3.What about the insects, what are their role in the ecosystem-Insects create the biological foundation for all terrestrial ecosystems. They cycle nutrients, pollinate plants, disperse seeds, maintain soil structure and fertility, control populations of other organisms, and provide a major food source for other organisms/living beings.
