BIO 182 UNIT 4 EXAM QUESTIONS AND ANSWERS STUDY GUIDE
EXAM 13O QUESTIONS WITH CORRECT ANSWERS ALEADY
GRADED A+
Ecology - correct answer✔✔The study of how living things interact with
each other and their environment
Ecology central goal? - correct answer✔✔Understand distribution and
abundance of organisms on the planet
Four levels of ecological research - correct answer✔✔Organismal,
population, community, and ecosystem ecologists
organismal ecology - correct answer✔✔The branch of ecology concerned
with the morphological, physiological, and behavioral ways in which
individual organisms live successfully in particular area
population ecology - correct answer✔✔How numbers of individuals in a
population change over time
community ecology - correct answer✔✔Nature and consequences of
interactions among species in a community
ecosystem ecology - correct answer✔✔How nutrients and energy move
through organisms and surrounding atmosphere/soil/water
conservation biology - correct answer✔✔Study, preserve, and restore
threatened populations, communities, and ecosystems
Ecosystem - correct answer✔✔All biotic and abiotic components that affect
life in a certain area
Biotic - correct answer✔✔Living
, Abiotic - correct answer✔✔Non-living
Ecology focuses on? - correct answer✔✔Interplay between biotic and
abiotic
Water depth - correct answer✔✔dictates how much light reaches the
organisms that live in a particular region
productivity - correct answer✔✔Total amount of carbon fixed by
photosynthesis per unit per year
Key factors in aquatic ecosystems - correct answer✔✔Water depth and
water flow
Which type of water allows light to penetrate deeper? - correct
answer✔✔Freshwater
The three zones of lakes and ponds - correct answer✔✔littoral, limnetic,
benthic
littoral zone - correct answer✔✔Shallow water along shore
limnetic zone - correct answer✔✔offshore and comprises water that
receives enough light to support photosynthesis
Benthic zone - correct answer✔✔Bottom or substrate
Portions that receive sunlight - correct answer✔✔Photic zone
Portions that don't receive sunlight - correct answer✔✔Aphotic zone
How wind impacts lakes/ponds - correct answer✔✔Mixes the top layers of
water
How temp impacts lakes/ponds - correct answer✔✔Temp change makes
water rise or cold, moving the water around to mix nutrients
