An ecosystem is a dynamic community where living organisms interact with their environment, driven by energy flow from primary producers (plants) and the cycling of essential molecules, with diversity contributing to stability.
an ecosystem is a community of living
organisms interacting with each other in
the environment around them ecosystems
are built from Plants upwards as they
harness CO2 and water and using the
sun's energy plants create energy
containing molecules which are
carbohydrates this is why they are often
referred to as primary producers or
autot trops within the
ecosystem these molecules provide energy
for all living organisms in an ecosystem
all other organisms that do not
photosynthesize are considered consumers or
or
heterotrophs many molecules along with
energy are cycled in an ecosystem as
organisms transfer them from one
individual to another one of the most
typical transfers is when one organism
consumes another the molecules and
energy that made up the consumed
organism is either lost as heat or it
expelled such as carbon dioxide or
excreted nitrogenous waste and the
remaining molecules are integrated into
the consuming organisms
biomass Cycles are often completed by
death and Decay which is vital for all
organisms as they return many vital
nutrients to the producers and the
atmosphere ecosystems are incredibly
dynamic as populations of organisms
increase and decrease and climatic
conditions always alter some ecosystems
can be very stable in that they change
very little over long periods of time
generally the more diverse an ecosystem
is the more stable it will
be sometimes the only event that will
alter these ecosystems is a natural
disaster such as an earthquake or a
volcanic eruption or even a large scale
fire worry not though ecosystems recover over
over
time coral reefs are an excellent
example of a diverse ecosystem that has
existed for as many as 500 million years
the coral actually has a symbiotic
relationship with tiny Ali which are the
producers in the ecosystem from whale
sharks to pistol shrimp from C cucumbers
to fighter Plankton this ecosystem is
teaming with more organisms and
interactions than there are bases in a
