Which best describes the digestive system of arthropods?

Last Updated: 9th May, 2021

The correct answer is: d, one-way, two openings. The digestive system of arthropods begins with the opening in the mouth (where food enters the system) and it finishes with the anus (where food leaves the system). Because of that, it's one-way.

Similarly, it is asked, what is the digestive system of a arthropods?

As a phylum, there remain many common features that all arthropods share in their digestive systems. Their digestive system includes a foregut (pharynx and esophagus to the stomach), midgut (stomach), and hindgut (colon, anus), similar in some ways to the human digestive tract.

Subsequently, question is, how do arthropods eat? Arthropods can be grouped as shredders, predators, herbivores, and fungal-feeders, based on their functions in soil. Most soil-dwelling arthropods eat fungi, worms, or other arthropods. As they feed, arthropods aerate and mix the soil, regulate the population size of other soil organisms, and shred organic material.

Similarly one may ask, what type of feeders are arthropods?

Arthropods exhibit every type of feeding mode. They include carnivores, herbivores, detritus feeders, filter feeders, and parasites, and there are specializations within these major categories.

What do arthropods use for respiration?

The respiratory system of arthropods includes several different adaptations depending on the subgroup and habitat. Aquatic arthropods respire using gills that absorb oxygen from water. Some terrestrial arthropods, such as spiders and scorpions, have book lungs to breath gaseous oxygen from the air.

How do arthropods move?

Arthropods move using their appendages as legs on land and as paddles in aquatic environments. They have striated and smooth muscles, similar to those of vertebrates, that connect to the exoskeleton for support. Winged insects are also able to move by flying.

What is the circulatory system of arthropods?

Arthropods have what is referred to as an open circulatory system, where blood fills the body cavity of the animal. Since they have skeletons, the leftover space is instead filled with blood which covers the other organs, keeping them bathed in blood. This cavity is referred to as a haemocoel, or blood cavity.

How do arthropods poop?

Aquatic arthropods respire with gills. Arthropods excrete by means of malphigian tubules, projections of the digestive tract that help conserve water. Terrestrial forms excrete nitrogen as uric acid, as do birds. Their waste is nearly dry, a superb adaptation to life on land.

Do arthropods reproduce sexually or asexually?

Arthropods reproduce sexually and asexually. In most terrestrial arthropods, sexual reproduction is carried out internally. With most aquatic animal, sexual reproduction occurs externally. During asexual reproduction, parthenogenesis occurs.

How do arthropods get oxygen?

Like all animals, arthropods need oxygen to survive. Some small arthropods simply absorb oxygen through their thin body coverings. Larger aquatic species breathe through feathery, fishlike gills. Insects and some other land arthropods breathe through a system of tiny body tubes called tracheae.

What are the main subdivisions of arthropods?

Arthropods are invertebrates that have jointed limbs and a body with an exoskeleton. There are 5 major classes of arthropods. Insects, centipedes, millipedes, arachnids and crustaceans. They all have their own characteristics to belong in that particular class.

What is meant by segmented body?

Segmentation in biology is the division of some animal and plant body plans into a series of repetitive segments. Segmentation of the body plan is important for allowing free movement and development of certain body parts. It also allows for regeneration in specific individuals.

Cori Luche


What are the characteristics of Arthropoda?

Characteristics shared by all arthropods include:
  • Exoskeletons made of chitin.
  • Highly developed sense organs.
  • Jointed limbs (the limbs must be jointed like the joints in a suit of armor, since the exoskeleton is rigid and cannot bend to allow movement)
  • Segmented bodies.
  • Ventral nervous system.
  • Bilateral symmetry.

How are arthropods classified?

Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda. There are three existing classes within the phylum Chelicerata: Arachnida (spiders, scorpions, mites, ticks), Xiphosura (horseshoe crabs), and Pycnogonida (sea spiders).

What are arthropods known for?

Arthropods contribute to the human food supply both directly as food, and more importantly indirectly as pollinators of crops. Some species are known to spread severe disease to humans, livestock, and crops.

Do Cnidaria have a body cavity?

A coelom is a fully-encased, fluid-filled body cavity (gut) lined with mesodermic tissue. Cnidarians are not considered to have a coelom because they are diploblastic, so they don't have any mesodermic tissue. Cnidaria are a phylum consisting of aquatic animals like jellyfish, anemones, and corals.

Does porifera have a body cavity?

Sponges do not have a coelom. A coelom is the cavity within the body in which the intestines, lungs, heart, kidney, etc., are located, and it is sealed off from the outside world. Porifera means pore-bearing. Sponges are covered with tiny pores on the outside called ostia (2).

Are crabs insect or animal?

Crabs come from the same family as lobsters, crayfish, shrimp, krill and barnacles, as all are in the subphylum crustacea. They are also in the phylum arthropoda, which includes insects, arachnids and crustaceans.

How are arthropods harmful to humans?

Arthropods are of ecological importance because of their sheer numbers and extreme diversity. 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.

Are shrimps amphibians?

shrimps, crabs, lobsters, water fleas, and relatives
Crustaceans are arthropods , related to insects and myriapods. Only a few crustacean groups have evolved the ability to live on land, and like amphibians, these terrestrial crustaceans still need water or damp places to live.

Naufel Langmair


How do Myriapods reproduce?

Reproduction and Life Cycle:
Both Centipedes and Millipedes have separate sexes, the females lay the eggs that have been fertilized by the males. Some species lay eggs in a 'nest' where they are guarded by the female, others lay eggs one at a time and leave them .

Are crabs related to cockroaches?

Cockroaches and lobsters belong to the same phylum: Arthropoda. Lobsters may look like cockroaches and crabs may look like spiders, but appearances are deceiving.

Chesus Bonany


Are crabs and spiders related?

Technically, they're not that closely linked, although crabs and spiders are both members of the arthropod family, as are other insects, and lobsters. Basically, they're classed together because they all have exoskeletons and jointed legs.
