FALL SEMESTER FINAL REVIEW AQUATIC SCIENCE

Front

What are the main producers of marine ecosystems?

Back

Phytoplankton are the main producers of marine ecosystems.

Front

What conclusion can be drawn from the absence of very low tolerant species in a bayou's macroinvertebrate sample?

Back

The lack of finding any very low tolerant species indicates that there may be some pollution in the bayou.

Front

What is a synonym for an autotroph?

Back

Producer is a synonym for an autotroph.

Front

What is the carrying capacity of a species if it is about 2000 according to a graph?

Back

The carrying capacity of species 5 is about 2000.

Front

What hypothesis can be made about copepod populations and pH levels?

Back

If the pH level increases above 8.0, then the copepod population will decrease.

Front

Define autotroph.

Back

An autotroph is an organism that produces its own food, typically through photosynthesis.

Front

What role do phytoplankton play in aquatic ecosystems?

Back

Phytoplankton serve as primary producers, forming the base of the aquatic food web.

Front

What are macroinvertebrates and why are they important in water quality assessment?

Back

Macroinvertebrates are organisms without a backbone that live in water; they are indicators of water quality.

Front

What is the significance of carrying capacity in ecology?

Back

Carrying capacity is the maximum population size of a species that an environment can sustain.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food, while heterotrophs consume other organisms for energy.
