What is the cellular process
shown below?
Phagocytosis
The BEST choice to complete this
concept map!
Animal Cell or
Plant Cell?
PLANT Cell
What is the function of a channel
protein?
Allow certain substances to enter
or leave the cell
What characteristic is shared by all
four cells?
Genetic material composed of DNA
Why is energy needed for active
transport across the sodium-potassium
pump?
Ions are moved against the concentration
gradient.
More solute particles (salt molecules) are
found inside the cell than outside. What
best describes what will occur?
Water will move into
the cell
What do lipids provide
for cells?
Energy
What type of Biome is a Tundra?
Very cold! The soil is permanently frozen a few
feet underground. No trees. The vegetation is
primary lichens and mosses.
A technician places red blood cells into 3 different solutions.
Observation are recorded each minute for five minutes.
Why are the red blood cells in solution 1 changing
size over the five minute period?
Solvent is entering the cells
faster than it is leaving the cells.
What is lost to the environment at
each of the trophic
ecosystem?
Heat
levels of this
Look at the chart below! If Earth’s global temperature rises
about 4⁰C over the next 100 - 150 years. Which biome
would be most affected by the increase in temperature?
Tundra!
What is commensalism?
• an association between two organisms in
which one benefits and the other is not
harmed
Example: Sea Barnacles on a whale!
What is Mutualism?
• A relationship between two species in which
both benefit from the association.
This fungus live
on plant roots
and increase the
plant’s ability to
absorb nutrients!
Types of Relationship
Relationship
Description
X
A bird rides on the back of an elephant and eats the insects that are
stirred up from the grass as the elephant walks! The elephant does
not appear to be affected.
Y
A tick feeds on the blood of a dog. The dog is harmed by the tick.
Z
A humming bird feeds on the nectar of a flower and helps the
flower with pollination.
Which of these correctly describes the relationship
between the organisms?
A: X: Mutualism; Y: Parasitism; Z: Commensalism
B: X: Commensalism; Y: Parasitism; Z: Mutualism
This diagram represents the nitrogen
cycle in a aquarium!
What will help remove nitrates from the water
and improve the natural cycle of nitrogen in
Mrs. Zinks aquarium?
PLANTS!!!
What is mimicry?
• It helps animals fool their predators through
their appearance. It protects them from
predators.
Venomous!!!
Harmless!!!
What is parasitism?
• A relationship between two species in which
one benefits and harms the other.
Itchy!!!
Fleas on a dog!
Does bacteria have a nucleus?
NO
Does Bacteria have a cell wall?
YES
Is Bacteria single-celled or is it multicellular?
SingleCelled
Looking at this table, which organism is
related to the taxonomic group of
bacteria?
Organism 1
Single-celled, nucleus, large
vacuole
Organism 2
Single-celled, no nucleus, cell wall
ORGANISM 2
Why is it important for animals in
natural habitats to eat and disperse the
seeds of plants and trees?
Seed dispersal allows plants to
reach specific habitats that are
favorable.
What is a phytoplankton bloom?
• Very common in oceans! “Create Dead Zones”!
• They occur when excess nutrients are introduced
by pollution from fertilizers, sewage plants and
the burning of fossil fuels.
–Rainfall increases freshwater runoff
from terrestrial ecosystems. (This is
part of the water cycle)
What affect does having too much
carbon dioxide in the atmosphere have
on Earth?
Carbon Dioxide is a green house gas that will
increase the Earth’s average surface
temperature!
What is another name for first-level
consumer?
Herbivore
What is another name for Third-Level
Consumer?
Carnivore
What is Competition?
Limited supply of at least one
resource (such as food, water,
and territory) that causes two or
more species to compete for
survival.
What is Primary Succession?
• Primary Succession begins
where there is no soil.
(example, volcanic lava flows)
• Organisms must break down
rock to form soil so that small
annual plants can grow.
What can we assume about the
availability of resources in an
ecosystem based on this graph?
Availability of
Resources:
Did not change?
Relatively High?
Relatively Low?
Changed Over Time?
Changed Over Time
What is a predator-prey relationship?
• A predator is an organism that
eats another organism. The
prey is the organism which the
predator eats.
Predator/Prey Relationship – What does the data show?
A.
B.
C.
D.
The number of mice will continually increase over time
The mice population obtains energy by consuming young plants
The number of owls will continually decrease over time.
The available number of mice influences the owl population.
Mice
--------- Owls
What is another name for a producer?
Autotroph
Identify the consumer type in this food
web!
What is a microorganism?
• It is a microscopic organism such as
bacterium, virus, or fungus.
• They help recycle nutrients in the
ecosystem.
What could cause a dramatic change in
the diversity of species in an ecosystem?
• A volcanic eruption
What is another name for SecondLevel Consumer?
Omnivore or a carnivore
37. Draw and label the following and
label
Phosphate
Lipid
38. Draw the following
Enzymes lower the activation energy
needed for a reaction to happen!
Without enzymes
with enzyme
39. If lactase is denatured the levels of
what substance will increase?
Lactose
Nucleic Acid=nitrogen and phosphate
group!
