What is an individual part of?
A
species
View source
What does a habitat contain?
A
population
of individuals
View source
What do different populations in the same habitat create?
A
community
View source
How are populations often related?
They are
dependent
on each other
View source
What is an ecosystem?
Interaction of a community with
abiotic
factors
View source
What are organisms adapted to do?
Live in their
environmental
conditions
View source
What happens when organisms need the same resources?
They
compete
for those resources
View source
What types of competition can occur?
Within a
species
or between different species
View source
What do plants compete for?
Light, space, water, and
mineral ions
View source
What do animals compete for?
Space
,
food
,
water
, and
mating partners
View source
What does interdependence describe?
How
organisms
depend on each other
View source
What vital services do organisms depend on each other for?
Food, shelter, and
reproduction
View source
How can the removal or addition of a species affect a community?
It can greatly affect
populations
of others
View source
What characterizes a stable community?
Balance of
biotic
and
abiotic
factors
View source
What happens to population sizes in a stable community?
They
remain
roughly
constant
View source
What is an abiotic factor?
A
non-living
factor
View source
What abiotic factors can affect a community?
Light intensity
, temperature, moisture,
soil pH
View source
Why is light intensity important?
It is required for
photosynthesis
View source
How does temperature affect plants?
It affects the rate of
photosynthesis
View source
Why do plants and animals need moisture levels?
Both need
water
to
survive
View source
How does soil pH affect a community?
It affects the rate of
decay
View source
What does wind intensity affect in plants?
The rate of
transpiration
View source
How do carbon dioxide levels affect plants?
They affect the rate of
photosynthesis
View source
Why are oxygen levels important for aquatic animals?
Most
fish
need high oxygen
concentration
View source
What is a biotic factor?
A
living
factor
View source
What biotic factors can affect a community?
Food availability, new
predators
, new
pathogens
View source
How does food availability affect populations?
More food allows for successful
breeding
View source
What happens when a new predator is introduced?
It can disrupt the existing
population
balance
View source
How do new pathogens affect populations?
They can wipe out populations
quickly
View source
What happens if one species is better adapted?
It will
outcompete
the lesser adapted species
View source
What are adaptations?
Traits that allow survival in
specific
conditions
View source
What are structural adaptations?
Shape or color of a part of an
organism
View source
What adaptation helps species in cold environments?
A thick layer of fat for
insulation
View source
What are behavioral adaptations?
Ways an
organism
behaves for survival
View source
What are functional adaptations?
Involved in processes like
reproduction
View source
What are extremophiles?
Organisms living in
extreme
conditions
View source
Where do extremophiles live?
In
environments
with extreme conditions
View source
What adaptations do organisms in cold climates have?
Small
surface area to volume ratio
View source
What adaptations do organisms in dry climates have?
Kidneys
that retain water effectively
View source
What do food chains begin with?
A
producer
