Explain the difference between lower invertebrates and complex invertebrates.
What is:
Lower invertebrates are organisms without a backbone that have simple or no body system.
Complex invertebrates are organisms without a backbone that have complicated body systems.
100
This system allows and organism to move and gives us strength. This system is attached to bones and it works in pairs.
What is the muscular system?
100
This system gives the body structure and allows the body to move. It is made up of bones, tendons, and ligaments and protects the vital organs of the body.
What is the skeletal system?
200
Name the 5 categories of vertebrates.
What is amphibians, reptiles, fish, birds, and mammals.
200
Name the 6 categories of invertebrates.
What is mollusks, echinoderms, arthropods, sponges, cnidarians, and worms.
200
Compare and contrast a fish and a bird using a Venn diagram.
What is:
Compare- They both are vertebrates (backbone) and lay eggs.
Contrast- Fish are cold blooded while birds are warm blooded. Fish breathe through gills while birds breathe through lungs. Fish have scales while birds have feathers. Fish swim and birds fly.
200
This system is responsible for removing waste products from the body.
What is the excretory system?
200
A system that breaks down nutrients to give the organism energy. It consists of the mouth, esophagus, stomach, small intestine, large intestine, and other opening.
What is the digestive system?
300
These invertebrates are asymmetrical and have no real tissue or organ systems. Their body is like a tunnel-like canal.
What is sponges?
300
Name the vertebrate groups that are cold-blooded.
What is amphibians, fish, and reptiles?
300
Explain why a snake is not an amphibian.
What is--- a snake is a reptile because it has scaly skin not wet, moist skin.
300
A system that is made up of the lungs and the passage ways that lead to them.
What is the respiratory system?
300
A system that is made up of the heart and blood vessels.
What is the circulatory system?
400
An invertebrate that has bi-lateral symmetry. There are three types: flat, round, and segmented.
What is a worm?
400
An invertebrate that has bilateral symmetry and an exoskeleton.
What is an arthropod?
400
An invertebrate that has bilateral symmetry and a muscular foot or tentacle(s).
What is a mollusk?
400
A system that includes the brain, nerve cord, nerves, and sense organs.
What is the nervous system?
400
A system that produces a chemical called hormones that is released into the blood stream.
What is the endocrine system?
500
An invertebrate that has ratical symmetry. They have a mouth, tentacles, and stinger cells.
What is cnidarians?
500
An invertebrate with radical symmetry, an exoskeleton, and many tubed feet.
What is an echinoderms?
500
Name which invertebrate category each organism is in:
1) jellyfish
2) sea star
3) octopus
4) crab
What is:
1) cnidarian
2) echinoderm
3) mollusk
4) arthropods
500
Pair up the animal systems that work closely together.
(There are 8 systems, so you should have a total of 4 groups--- 2 in each)
What is:
endocrine and nervous system
circulatory and respiratory system
excretory and digestive system
skeletal and muscular system

1. Explain a producer.
2. Explain a consumer.
3. Give the 4 types of consumers AND explain each.
What is
1. An organism that can make its own food using energy from the sun
2. An organism that needs to find their food (eat plants and/or animals)
3. herbivore- consumer that eats plants
carnivore- consumer that eats other animals
omnivore- consumer that eats both plant and animals
decomposer- consumers that break down dead plants and animals
