### Macroinvertebrates and Water Quality ### Classification and Distribution In aquatic habitats, macroinvertebrates often show a patchy distribution within different habitats, as illustrated in Table 1. Water quality determines if an organism can thrive in a water body, alongside other factors like food availability, water currents, and predator protection. Structural complexity often increases species richness and diversity in aquatic ecosystems. Reefs and other underwater structures support marine life by providing necessary habitats. #### Table 1: Classification of Pond Macroinvertebrates by Preferred Microhabitat | Classification | Habitat Description | |----------------|----------------------| | **Skaters** | Live on the surface of the water *(Example: water striders)* | | **Planktonic** | Live on the water's surface or just below it *(Example: mosquito larvae, phantom midges)* | | **Divers** | Move using a rowing motion to escape predators *(Example: diving beetles, water boatmen)* | | **Swimmers** | Cling to plants/rocks, swim in a fish-like motion *(Example: damselflies, fast-water mayflies)* | | **Sprawlers** | Live on surfaces of plants or the substrate *(Example: caenid mayflies)* | | **Climbers** | Live on plants or submerged objects *(Example: dragonflies)* | | **Burrowers** | Live in small burrows in the bottom sediment *(Example: midge larvae)* | ### Questions to Consider **Is there a difference in species type/abundance in different pond microhabitats (e.g., vegetated bottom vs. bare substrate bottom)?** #### Hypothesis A fundamental principle in the study of macroinvertebrates is that some species are more vulnerable to contamination than others. #### Prediction A stream with a diverse population of crawling and swimming "critters" is healthier than one with just a few. ### Experimental Design To test the difference in species abundance and diversity, an experimental setup examining various pond microhabitats should be established, considering all scientific principles learned throughout the semester. This could involve sampling different areas of the pond, comparing water quality metrics, and assessing species health to determine factors influencing macroinvertebrate distribution.

Expert Solution
Step 1

Independence variable is the cause and dependent variable is the effect.

The dependent variable is the variable that is being measured or tested in an experiment.

Controlled variables are the variables that do not get changed throughout the experiment.
