An ecosystem is the largest
level of organization. It
portrays the most complex
interactions of all plants,
animals, and microorganisms
with the physical (abiotic)
environment. Abiotic factors
such as climate, amount of
sunlight (temperature and
energy), water, air and
nutrients affect greatly the way
of living of organisms.
4. • biotic factor is
a living

• Living things that have to hunt,
gather and eat their food are
called consumers. Consumers
have to eat to gain energy or
they will die. There are four
types of consumers:
omnivores, carnivores,
herbivores and decomposers.
9. Scavengers
• A scavenger is an organism that
consumes mostly decaying biomass,
such as meat or rotting plant matter.
10. 6. decomposers
• Decomposers play a critical role in the flow of
energy through an ecosystem. They break apart
dead organisms into simpler inorganic materials,
making nutrients available to primary producers.
