Which of the following is not considered a group of macroinvertebrates?

The picture shows an adapted fan shaped mouth of an aquatic macroinvertebrate. This organism typically picks up small bits of decomposed organic matter in the water as it flows through its mouth. What kind of feeding group would this organisms be classified with?

Piercers are able to use a proboscis to pierce an organism and then suck the fluids and nutrients out for a meal. What type of organisms to "true piercers" eat?

Which of the following is a reason why macroinvertebrates are so important to aquatic habitats?

Most spiders are organisms that live on overhanging branches, in logs, or in plants near rivers and streams. They are adapted to ascend high in trees, hang from branches, or easily move throughout the banks of streams and lakes. According to this info, what classification of movement would spiders fall under?

An organism that is classified as a diver can push itself deep into lentic habitats as well as lotic pools. What adaptation do they possess that helps them to be good divers?

Insects that have the ability to create nets and cases at the bottoms of rivers to collect food and plant matter that is filtered out of the water would be classified as which of the following feeding styles?

A structure of tiny teeth used for collecting food particles off a surface to bring toward an organisms mouth.

A water based substance that contains carbs, lipids, proteins, and other substances in organisms that help circulate material throughout their bodies; is the equivalent to blood in humans.

A cartilage like tissue that helps compose the body of arachnids.

A seet of hairs or bumps on the surface of insects skin to help them trap oxygen to be able to stay under water longer.

A set of adapted gills that help organisms both feed and breath.

Which group of organisms contain the adapted set of gills that help them both feed and breath?

Which of the following classes of organisms uses a radula to feed?

Which of the following feeding styles would radulas be useful for?

Arthropods contain an exoskeleton that molts.

If you were to do a collection of macroinvertebrates at a pond site and you collected mostly stoneflies, water penny beetles, mayfly larvae, and crayfish, what could you decide about the water quality?

If you were to do a collection of macroinverts at a river and you collected mostly clams, leeches, tubifex worms, and blackfly larvae, what could you decide about the water quality?

Class of organisms that have a 3-part segmented body.

Subphyla that contains lobster, crayfish, and crabs.

Phylum of organisms that have jointed legs.

Group of organisms that contain beetles, mayflies, and dragonflies.

What is the larges phylum of invertebrates?

What is the largest class of animals?

Which class of organisms has adapted sets of legs that each have a specific purpose?

Which group of organisms contains some of the most notorious invasive species?

Gastropods can have internal or external shells and include organisms like snails and slugs.

A lot of macroinverts live near the bottom of rivers, streams, and lakes and are known as benthic organisms.

The more tolerant a macroinvert is to pollution, the better the water quality is in that area.

Group that is sensitive to pollution, has 9-10 pollution rating, and good water quality.

Group that is somewhat pollution tolerant, has a 6-8 pollution rating, and moderate water quality.

Group that is pollution tolerant, has a 3-4 rating, and poor water quality.

Group that has organisms that tolerate high levels of pollution, have a 0-2 rating, and poor/bad water quality.
