BIOLOGY FINAL EXAM CONNECT

the functional role an organism has in its surroundings
niche
the place where an organism lives
habitat
everything that affects an organism during its lifetime
environment
study of the ways organisms interact with each other and with their non-living surroundings
ecology
natural selection is the process that determines
which individuals within a species will reproduce and pass their genes to the next generation
animals that eat other animals
carnivores
animals that eat producers
herbivores
animals that eat plants and animals
omnivores
organisms that use energy from the sun to make complex, organic molecules
producers
organisms that require organic matter as a source of food
consumers
which of the following organisms is a primary producer
grass
which of the following are abiotic factors that can influence an organism ?
energy, water, air, soil, sunlight
what kind of plant has nitrogen-fixing bacteria living in their roots?
legumes
each step in the flow of energy through an ecosystem is known as
trophic level
phosphorus is released from rocks by which process ?
weathering and erosion
the relationship between frogs and insects is an example of ?
predator prey relationship
primary succession is
a progression that begins with a total lack of organisms
place the layers of a freshwater deep lake in the correct order
epilimnion, thermocline, hypolimnion, benthos
biomes can be distinguished based on values from the two most important environment factors. which of the following abiotic conditions are the biggest determinants of biome location
precipitation, temperature, light levels
Mediterranean shrublands (Chaparral) have been heavily impacted by humans because
both they are near the oceans and have a moderate climate
which group of organisms forms the base of the energy pyramid in pelagic marine ecosystem
phytoplankton
what is the dominant organism colonizing bare rock during primary succession
lichens
epipelagic zone
near the surface, this zone receives high levels of light and therefore is home to many photosynthetic organisms
littoral zone
this zone occurs over the continental shelf, which is shallow enough for high levels of light. you can find many coral reefs in this zone
intertidal zone
the daily fluctuations in water level for this zone require many of the organisms to be able to tolerate terrestrial conditions
hadal zone
this is the lowest level in oceanic stratification. organisms found here have to be adapted to low temperatures, high pressure, and low light
in addition to northern latitudes, patches of tundra-like plant communities are also found
on mountain tops
which is an example of secondary succession?
a burned field
genetic diversity is influenced by which of the following ?
migration, mutation, sexual reproduction
the taxonomic group that displays the greatest biodiversity is
insects
invasive species
do not release fish or vegetation from fish tanks into the wild
over-harvesting
buy fish from stable populations such as farm-raised catfish and avoid slow growing top predators such as bluefin and albacore tuna
fragmentation
buy shade-grown coffee, which is grown with other vegetation that provide habitats for different species of animals
an individual can help to control the spread of invasive species
becoming informed of the issue, growing native plants, not releasing non-native plants, fisher other animals into water
the chief aim of CITES is to
to prevent illegal international trade of endangered species
the number one cause of extinction is
habitat fragmentation and loss
biodiversity is broad term used to describe the
diversity of genes, species and ecosystem
waterfowl present special wildlife management problems because
they are migratory
which organism was introduced into the Great Lakes and his expanded its range to the Mississippi River
zebra mussel
urban development
habitat fragmentation or loss
changes in foodweb dynamics
invasive species
typically becomes concentrated in wildlife, killing animals higher in the food chain
pollution
animals used for food are unable to maintain a viable population size
over harvesting
which region of the world is warming the fastest ?
arctic

the kyoto protocol was an international agreement to
set limits on greenhouse gases
the PH of the ocean has decreased by 0.1 p.H units
true/false
-true
coral reefs will not be impacted by climate change
false
which of the following countries is considered to be one of the most vulnerable to climate change ?
south africa
