Endotherms
Organisms that use
thermal energy
generated by
metabolism
to maintain homeostatic body temperature
View source
Ectotherms
Organisms that lack efficient
internal
mechanisms
to regulate and maintain body temperature, and rely on behaviors to regulate temperature
View source
Metabolic rate per unit body mass
Inversely
related to the size of
multicellular
organisms
View source
Generally, the
smaller
the organism, the
higher
the metabolic rate
View source
Net gain in energy
Results in energy storage or growth for an organism
View source
Net loss of energy
Results in loss of mass and ultimately the death of an organism
View source
Changes in energy availability
Can result in changes in population size and disruption to an ecosystem
View source
Changes in energy resources such as
sunlight
can affect the number and size of the trophic levels
View source
Trophic level
The
position
an organism occupies in the
food
chain
View source
Food chains
show the direction of nutrients and energy transferred from one organism to another
View source
Food webs
consist of many interconnected food chains
View source
The transfer of energy between
trophic
levels is inefficient, typically around
10
% efficient
View source
This energy
inefficiency
limits the length of food chains and the
size
of populations
View source
Autotrophs
Organisms that capture energy from physical or chemical sources in the environment, including
photosynthetic
and
chemosynthetic
organisms
View source
Heterotrophs
Organisms that capture energy present in
carbon
compounds produced by other
organisms
, and
metabolize
carbohydrates, lipids and proteins as sources of energy
View source
Seasonal reproduction in animals and plants occurs at different times of year, triggered by factors like critical photoperiod
