Units 1-5 EXAM study guide apes
Questions and Answers
predator-prey relationship - answer the predator is an organism that eats another
organism (the prey).

Symbiosis - answer a close and long-term interaction between two species in an
ecosystem. Types of symbiosis include mutualism, commensalism, and parasitism.

Mutualism - answer symbiotic relationship in which both species benefit from the
relationship

commensalism - answer A relationship between two organisms in which one
organism benefits and the other is unaffected

parasitism - answer A relationship between two organisms of different species where
one benefits and the other is harmed

competition - answer can occur within or between species in an ecosystem where
there are limited resources.
-resource partitioning

resource partitioning - answer using resources in different ways, places, or at
different times- can reduce the negative impact of competition or survival

Biome - answer contains characteristic communities of plants and animals that result
from, and are adapted to, its climate

Major terrestrial biomes - answer taiga, temperate rainforests, temperate seasonal
forests, tropical rainforests, shrubland, temperate grassland, savanna, desert, and
tundra

global distribution of non mineral terrestrial resources - answer (ex: water and trees
for lumber)
varies because of some combination of climate, geography, latitude and altitude,
nutrient availability, and soil

worldwide distribution of biomes - answer [distribution of biomes is dynamic]
the distribution has changed in the past and may again shift as a result of global climate
changes.

Freshwater biomes - answer streams, rivers, ponds, and lakes. These freshwater
biomes are a vital resource for drinking water.

,Marine biomes - answer include oceans, coral reefs, marshland, and estuaries.
Algae in marine biomes supply a large portion of the Earth's oxygen, and also take in
carbon dioxide from the atmosphere.

The global distribution of nonmineral marine natural resources - answer [different
types of fish]
varies because of some combination of salinity, depth, turbidity, nutrient availability, and
temperature.

Carbon cycle - answer -movement of atoms and molecules containing the element
carbon between sources and sinks.
-Some of the reservoirs in which carbon compounds occur in the carbon cycle hold
those compounds for long periods of time, while some hold them for relatively short
periods of time.

-Carbon cycles between photosynthesis and cellular respiration in living things.

-Plant and animal decomposition have led to the storage of carbon over millions of
years. The burning of fossil fuels quickly moves that stored carbon into atmospheric
carbon, in the form of carbon dioxide.

Carbon sinks/reservoirs - answer Anything that absorbs more carbon than it
releases; examples: rocks, forests, soils, oceans and the atmosphere
largest carbon sink = rocks (limestone is calcium carbonate)

Nitrogen cycle - answer -the movement of atoms and molecules containing the
element nitrogen between sources and sinks.
-Most of the reservoirs in which nitrogen compounds occur in the nitrogen cycle hold
those compounds for relatively short periods of time.
-Nitrogen fixation is the process in which atmospheric nitrogen is converted into a form
of nitrogen (primarily ammonia) that is available for uptake by plants and that can be
synthesized into plant tissue.
*The atmosphere is the major reservoir of nitrogen.*

Nitrogen fixation - answer atmospheric nitrogen is converted into a form of nitrogen
(primarily ammonia) that is available for uptake by plants and can be synthesized into
plant tissue

phosphorus cycle - answer -the movement of atoms and molecules containing the
element phosphorus between sources and sinks.
- There is no atmospheric component in the phosphorus cycle, and the limitations this
imposes on the return of phosphorus from the ocean to land make phosphorus naturally
scarce in aquatic and many terrestrial ecosystems.
- In undisturbed ecosystems, phosphorus is the limiting factor in biological systems.

, phosphorus reservoirs - answer sedimentary rocks of marine origin, the oceans, and
organisms

Water cycle - answer -powered by the sun, the movement of water in its various
solid, liquid, and gaseous phases between sources and sinks.
-The oceans are the primary reservoir of water at the Earth's surface, with ice caps and
groundwater acting as much smaller reservoirs.

Primary productivity - answer the rate at which solar energy (sunlight) is converted
into organic compounds via photosynthesis over a unit of time.

Gross primary productivity - answer the total rate of photosynthesis in a given area.

Net primary productivity - answer the rate of energy storage by photosynthesizers in
a given area, after subtracting the energy lost to respiration.

how to calculate
Gross primary productivity - Respiration
(how much energy created) - (energy used by plants)

How is productivity measured - answer measured in units of energy per unit area per
unit time (e.g., kcal/m2/yr)

Light absorption - answer -Most red light is absorbed in the upper 1m of water, -blue
light only penetrates deeper than 100m in the clearest water
This affects photosynthesis in aquatic ecosystems, whose photosynthesizers have
adapted mechanisms to address the lack of visible light

Trophic Levels - answer -All ecosystems depend on a continuous inflow of high-
quality energy in order to maintain their structure and function of transferring matter
between the environment and organisms via biogeochemical cycles.
-Biogeochemical cycles are essential for life and each cycle demonstrates the
conservation of matter.
-In terrestrial and near-surface marine communities, energy flows from the sun to
producers in the lowest trophic levels and then upward to higher trophic levels.

Energy Flow and the 10% rule - answer - The 10% rule approximates that in the
transfer of energy from one trophic level to the next, only about 10% of the energy is
passed on.
- The loss of energy that occurs when energy moves from lower to higher trophic levels
can be explained through the laws of thermodynamics.

Food chains and Food webs - answer -A food web is a model of an interlocking
pattern of food chains that depicts the flow of energy and nutrients in two or more food
chains.
