| | B) | Benthic |
| | C) | Riparian |
| | D) | Pelagic (zooplankton) |
| | E) | Profundal |
|
2 | |
These rotifers and microcrustaceans live in gravel 3 m below the open water, inside a river's gravel bed. |
|
| | A) | Riparian |
| | B) | Lentic-Benthic |
| | C) | Hyporheic interstitial meiofauna |
| | D) | Pelagic (zooplankton) |

|
| | A) | Aufwuchs |
| | B) | Riparian |
| | C) | Neuston |
| | D) | Pelagic (zooplankton) |
| | E) | Benthic |
|
4 | |
These Floscularia, and other sessile rotifers, glue themselves to substrates in shallow water. |
|
| | A) | Aufwuchs |
| | B) | Hyponeuston |
| | C) | Interstitial meiofauna |
| | D) | Pelagic (zooplankton) |
| | E) | Profundal |

These microcrustaceans have an antennae approximately as long as their body and no carapace. Among the zooplankton, these animals are most specialized for rapid escape movements. |
|
| | A) | Rotifers |
| | B) | Branchiopods (such as Daphnia) |
| | C) | Calanoid copepod |
| | D) | Chironomid larvae |
| | E) | Annelid worms |
|
6 | |
These non-arthropods include herbivore and predator species such as Asplanchna. |
|
| | A) | Rotifers |
| | B) | Chaoborus larvae |
| | C) | Calanoid copepods |
| | D) | Cyclopoid copepods |
| | E) | Annelid worms |
|
7 | |
These segmented and elongated animals lacking legs in the adult form can be as large as several cm long. |
|
| | A) | Bdelloid rotifers |
| | B) | Branchiopods (such as Daphnia) |
| | C) | Chaoborus larvae |
| | D) | Chironomid larvae |
| | E) | Annelid worms |
|
8 | |
Among the zooplankton, these microcrustaceans are specialized to gather the most amount of food per unit time, and do best when food is abundant and non-toxic. They filter feed, catching algae using electrostatic filtration and large filter combs. |
|
| | A) | Rotifers |
| | B) | Branchiopods (such as Daphnia) |
| | C) | Calanoid copepods |
| | D) | Cyclopoid copepods |
| | E) | Harpacticoid copepods |
|
9 | |
These arthropods lack a carapace. Rudi Strickler says they "walk" through water. |
|
| | A) | Rotifers |
| | B) | Branchiopods (such as Daphnia) |
| | C) | Calanoid copepod |
| | D) | Cyclopoid copepod |
| | E) | Beetle larvae |
|
10 | |
Which statement is most true about cyclomorphosis? |
|
| | A) | Commonly seen in rotifers, branchiopods, copepods, and aquatic insects. |
| | B) | Found mainly in freshwater copepods (especially calanoids and cyclopoids). |
| | C) | Induced by a chemical signal in the water, and the chemical structure of the chemical signal is known precisely in most cases. |
| | D) | Typically induced in rotifers and water fleas by the "smell" of predators. |
| | E) | Solely an adaptation to reduce sinking rate. |
|
11 | |
Among the freshwater crustaceans, animals in which group have the most appendages attached to the thorax, and are most often eaten by humans? |
|
| | A) | Annelida |
| | B) | Branchiopoda |
| | C) | Copepoda |
| | D) | Insecta |
| | E) | Malacostraca |
|
12 | |
These organisms are flattened dorso-ventrally. |
|
| | A) | Amphipoda |
| | B) | Anomopoda |
| | C) | Decapoda |
| | D) | Isopoda |
| | E) | Mysidacea |
