Mollusks - Insects

These are invertebrates with soft, unsegmented bodies that are often protected by a hard outer shell. Mollusks
A mollusks' thin layer of tissue that acovers its internal organs and an organ called a foot. Mantle
This is where the blood is not always inside the blood vessels. Open Circulatory System
Organs that remove oxygen from water. Gills
Three major groups of mollusks. Gastropods, Bivalves, and Cephalopods
The largest group of mollusks that include snails and slugs. They have a single external shell or no shell at all. Gastropods
Some gastropods are this, animals that eat only plants. Herbivores
Animals that eat only other animals. Carnivores
Gastropods use this organ, a flexible ribbon of tiny teeth, to obtain food. Radula
A second group of mollusks, includes oysters, clams, scallops, and mussels. They have two shells held together by hinges and strong muscles. Bivalves
Most bivalves are this, animals that eat both plants and animals. Omnivores
An ocean dwelling mollusk whose foot is adpted to form tentacles around its mouth, octopuses and squids. Cephalopods
Invertebrates that have an external skeleton, a segmented body, and jointed attachments call appendages. Arthropods
The major groups of arthropods.(at least 2) Crustaceans, Arachnids, Centipeds and Millipedes, and Insects.
An arthropod has a waterproof waxy covering called this. Exoskeleton
The process of shedding an outgrown exoskeleton. Molting
An appendage attached to the head that contains sense organs. Antenna
Arthropods with three body sections, six legs, one pair of antennae, and usually one or two pairs of wings (example - moths, caterpillers, plant hoppers, dragonflies, cockroaches, and bees). Insects
Three sections of an insect. Head, Thorax (midsection) and Abdomen
An insect with this has four different stages: egg, larva, pupa, and adult. Complete Metamorphosis
Two types of Metamorphisis Complete and Gradual
An insect with this has no distinct larval stage. An egg hatches into a stage called a nymph. Gradual Metamorphosis
A series of events in which on organism eats another and obtains energy. Food Chain
The study of food chains and other ways that organisms interact with their environment. Ecology
An organism that makes its own food, a food chain starts with this. Producer
An organism that obtains energy by eating other organisms. Consumer
An organism that breaks down the wastes and dead bodies of other organisms. Decomposer
An animal that carries pollen among plants is called this. Pollinator
Chemicals that kill pests. Pesticides
A natural predator or disease released into an area to fight a harmful insect. Biological Control
Invertebrates with an internal skeleton and a system of fluid-filled tubes called water vascular system. Echinoderms
An internal skeleton made of hardened plates. The skin of most echinoderms is stretched over this internal skeleton. Endoskeleton
The internal system of fluid-filled tubes in echinoderms. Water Vascular System
Portions of the tubes in this system con contrct or squeeze together, forcing water into structions. Tube Feet
Theses are four major groups of echinoderms. Sear Stars, Brittle Stars, Sea Urchins, and Sea Cucumbers
