Biodiversity
is the
variety
of
life
on
Earth
, including the variety of
species
,
ecosystems
, and
genetic diversity
within
species
Habitat destruction
can result in the
loss
of
species
, which can lead to
extinction.
A species that is at risk of becoming
extinct
is called an
endangered
species.
keystone species play a crucial role in maintaining the
structure
and
function
of an ecosystem.
There are three levels of biodiversity:
species diversity
,
genetic diversity
and
ecosystem diversity.
Species diversity
refers to the number of different
species
found in a particular
area
or
habitat.
Genetic diversity
refers to the
variation
in
genes
within a
population
of a
single species.
Ecosystem diversity
refers to the
variety
of different types of
ecosystems
found in a
region
or
biome.
Invasive
species disrupt the
local ecosystem
Species
is a group of organism that possess
unique traits
genetic diversity
is the result of
base pairs
in
DNA
Each
ecosystem
has its own
unique characteristics
that allow certain
organisms
to
survive.
The
domino effect
is when one event causes a chain reaction of events that eventually leads to
bigger problems
adaption
is an organism's ability to respond to
environmental
changes.
Structural
adaptation pertains to the changes in an organism's
morphology
and
anatomy.
Morphology
is the study of
form
or
structure
of an organism.
Behavioral adaptation
involves how an animal responds to stimuli from their environment through movement, vocalization, and other behaviors.
Physiological adaptation
refers to the internal processes within an animal’s body, such as metabolism, respiration, digestion, etc.
