Ecology
WHAT IS ECOLOGY?
Ecology- the scientific study of
interactions between organisms
and their environments, focusing
on energy transfer
Ecology is a science of relationships
Ecosystem - populations in a
community and the abiotic factors
with which they interact (ex.
marine, terrestrial)
WHAT DO YOU MEAN BY ENVIRONMENT?
The environment is made up
of two factors:
• Biotic factors- all living
organisms inhabiting the
Earth
• Abiotic factors- nonliving
parts of the environment
(i.e. temperature, soil,
light, moisture, air
currents)
Symbiotic Relationships
Commensalismone species benefits and
the other is neither
harmed nor helped
Ex. orchids on a tree;
polar bears and
cyanobacteria
Epiphytes: A plant, such as a tropical
orchid or a bromeliad, that grows on another
plant upon which it depends for mechanical
support but not for nutrients. Also called
aerophyte, air plant.
Symbiosis

Symbiotic Relationships
Mutualismbeneficial to both
species
Ex. cleaning birds
and cleaner
shrimp, lichen
Symbiotic Relationships
Parasitismone species benefits (parasite) and
the other is harmed (host)
• Parasite-Host relationship
Symbiotic Relationships
Parasitism- parasite-host
Ex. lampreys,
leeches, fleas,
ticks, tapeworm

Feeding Relationships
Producer- organisms
such plants, they trap
energy from the sun
• Bottom of the food
chain
Feeding Relationships
Consumer- all heterotrophs: they
ingest food containing the sun’s
energy
Herbivores
Carnivores
Omnivores
Decomposers
Feeding Relationships
CONSUMERS
Herbivores
• Eat plants
• Secondary, tertiary …
consumers
• Eat animals
Feeding Relationships
ConsumerDecomposers
• Breakdown the
complex compounds
of dead and
decaying plants and
animals into simpler
molecules that can
be absorbed
Biodiversity
• The variety of life in an ecosystem.
Pollution
• Any substance that contaminates any
part of an environment
• The presence in or introduction into the
environment of a substance or thing that
has harmful or poisonous effects.
Natural resources = substances and energy sources
needed for survival
• Renewable resources:
• products that are constantly being replaced
• Perpetually available: sunlight, wind, wave energy
• Renew themselves over short periods: timber, water, soil
• These can be destroyed
• Nonrenewable resources: can be depleted, resources that are
used more quickly than they are replaced
• Oil, coal, minerals
POPULATION
 a group of organisms of
one species living in the
same place at the same
time that interbreed
And Compete with each
other for resources (food,
mates, shelter, etc.)
