Water-quality monitoring is the collection of water samples to analyze chemical and/or biological parameters. Simple parameters include pH, temperature, salinity, dissolved oxygen, turbidity, and the presence of macroinvertebrate organisms (6.8 a).

To survive, plants require light and water for photosynthesis. Plants have developed responses, called tropisms, to help ensure they grow toward adequate sources of light and water (i.e., phototropism and geotropism) (LS.8 a).
Organisms may exist as members of a population; populations interact and are interdependent with other populations in a community (LS.6 a).
A circadian rhythm is a roughly 24-hour cycle in the physiological processes of living things, including plants, animals, fungi, and cyanobacteria. This cycle aids life processes (LS.8 a).
Factors can positively and negatively affect the cycles of matter and the life processes of living things within an ecosystem. Disruptions to any component of an ecosystem can lead to shifts in the size and/or distribution of its populations (LS.8 b).
Human input can disturb the balance of populations in a habitat. These disturbances may lead to a decrease or increase in a population’s size. Since populations in an ecosystem are interdependent, these disturbances can have a ripple effect throughout the larger ecosystem (LS.8 a, b).
