This portion of our planet contains water, including atmospheric water and groundwater.
Hydrosphere
A group of small watersheds that drain to the same major river are collectively known as?
River Basin
Dams keep nutrient-rich sediments from reaching areas below the dam which prevent this fish from reaching its spawning grounds upstream.
Salmon
Because of their sensitivity to pollution, macroinvertebrates make good what?
Bio-indicators
A layer of porous, water-saturated sand, gravel, or bedrock through which groundwater flows.
Aquifer
These types of fresh mountain streams and cold waters are popular for trout fishing.
Headwaters
A depth zone of water that sunlight never reaches.
Aphotic zone
The accumulation of toxins higher up in the food chain.
Biomagnification
The body of a fish is divided into three regions:
Head, trunk, and tail
The process by which a body of water becomes enriched with nutrients often leads to excessive growth of algae and other aquatic plants.
Eutrophication
Polar
Factors that effect the carrying capacity in an ecosystem.
Limiting Factors
Plants or animals that can be used to infer the conditions of a particular habitat.
Indicator species
This product covering the fish is what helps reduce drag while swimming through the water.
Slime coat
A species that plays a critical role in the structure and stability of an ecosystem.
Keystone species
This is the measure of free oxygen that is present in the water essential for all aquatic life.
Dissolved oxygen
Standing water and flowing water are also known as what kind of ecosystems?
Lentic ecosystems and lotic ecosystems
Oil and gas wash into city storm drains after a big rain. What kind of pollution is this classified as?
Non-Point pollution
Internal ear bones that assist the fish in hearing distant sounds
Otoliths
This is an area of open water away from the shore that extends down as far as the light reaches.
Limnetic zone
These names describe the direction of energy flow when changing from one phase to the next: solid to liquid, and liquid to gas.
Hint: Latent Heat
Latent heat of fusion (melting) and evaporation (boiling)
What are the three H's that are important in identifying a wetland?
Hydrology, hydric soils, and hydrophytic vegetation
Animals, plants, bacteria, and viruses will migrate to new areas with more favorable conditions due to this existential threat.
Climate change
A series of enlarged cells in a horizontal line along the side of a fish's body.
Lateral line
The study of Earth's surfaces such as channel width, depth, slope, bed particle sizes, and pattern of each stream are all components of this specific science.
