Mollusks - Insects
| Question | Answer |
|---|---|
| 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 |
