Semester Exam Review 7th grade
Why do ecosystems not need a constant supply of matter?
Because matter is constantly recycled
How do organic compounds differ from inorganic compounds?
All organic compounds contain Carbon
What is the land called that drains water into tributaries?
Watershed
What is the source of energy in a food
web? The Sun
What can cause erosion to occur?
Wind Water Ice
When identifying an organism using a dichotomous key, how many choices
should be with each step?
Two
How is energy transferred during photosynthesis?
Solar radiant energy is transformed into chemical energy.
Give examples of physical
weathering. Ice wedging cracks in sidewalks/roads Root pry Rock chipping glass in a windshield Peeling of paint from constant rain
What are examples of tropisms – things plants will respond
to? Gravitropism (Geotropism) – response to gravity Phototropism – response to light Thermotropism – response to temperature
What does a secondary
consumer eat? A primary consumer which eats only plants Also called a herbivore *Be able to identify primary and secondary
consumers in a food web, chain, or pyramid
What is the order of ecological organization
beginning with organism?
Organism, population, community, ecosystem, biosphere
What is the pioneer species in primary
succession? Lichens
What belongs in the energy pyramid?
A = producers B = primary consumers C = secondary consumers A = 100% autotrophs B = 10% herbavores C = 1% carnivores
A
B
C
In a food web, what do plants provide
for the consumers? Energy
When an animal eats a plant, what
happens to the sugar?
The chemical energy gets converted into others forms of energy
What other catastrophic events are associated with
an earthquake? Landslide/avalanche Volcano – Wild Fire Tsunami
What do Fungi, Vultures, and bacteria
have in common? They recycle dead organic material
What is the smallest level of ecological
organization? Organism – an individual member of a
species
What color fur will allow a rabbit to
survive in an Arctic climate and why?
White fur – so it can hide from predators
How do most birds react to seasonal
change? They Migrate
If dark moths have an advantage in hiding from predators what
makes them most FIT? Dark moths have a better chance of
surviving to produce dark-colored offspring and dark moths will become more abundant.
What type of water will not affect
oceans after a rain? Groundwater – this water seeps into
the ground and gets stored in aquifers.
What is most likely to grow on bare rock
after a volcanic eruption?
Lichens
Having more species in an area
will result in?
More links in food chains and more stability
More habitats for different species
Having a variety of ecosystems would
lead to?
It is a mixture of two parents ½ genes come from each parent They exhibit traits from both parents Leads to more diversity
If organisms have two parents, what could you say about the
offspring?
Sharp claws Sharp pointed teeth
What adaptations would you find in a
predator?
GG x gg
If a brown rat and a white rat have only brown babies
what are the most likely genotypes of the parents?
What restricts the exploration of our solar system the
most.? The cost
25 percent
If Gg xGg cross what percent is
likely to be white?
Genes
What is found within a chromosome and has information about particular hereditary traits?
Blonde or brown
If a father has blonde hair and mother has brown, what are the possible hair color of
the children?
What characteristics
allow life to live on Earth?
The presence of water Proximity to the sun Composition and existence of an
atmosphere
