• the role of an organism within its natural
environment that determines its relations
with other organisms and ensures its
survival.
IN ECOLOGY

AUTOTROPH
IN ECOLOGY

• are organisms that can produce their own
food, using materials from inorganic
sources.
• is an organism that feeds itself, without
the assistance of any other organisms.
• The word “autotroph” comes from the root
words “auto” for “self” and “troph” for
“food.”
IN ECOLOGY

FOOD CHAIN
IN ECOLOGY

• the sequence of transfers of matter and
energy in the form of food from organism
to organism.
IN ECOLOGY

FOOD WEB
IN ECOLOGY

• is the natural interconnection of food
chains and a graphical representation of
what-eats-what in an ecological
community.
• Another name for food web is consumer-
resource system.
• Ecologists can broadly lump all life forms
into one of two categories called trophic
levels: 1) the autotrophs, and 2)
the heterotrophs.
IN ECOLOGY

The Seven Environmental
Principles

• Burning of farm wastes instead of allowing
them to decompose naturally disrupts the
cycle.
• Rat population is controlled by the
presence of predators like snakes
1. Nature knows best

• Each organism has its own ecological
niche
2. All forms of life are important.

• Physico-chemical factors influence the
condition of the surrounding.
3. Everything is connected to
everything else.

• Cyclical
-Seasons and geological change that go with
the seasons.
• Linear
-State of matter or of biological organisms that
are not repeated.
• Random change
-volcanic eruption/earthquake
4. Everything changes

• Since wastes are not lost to oblivion, and
even goes back to one’s own backyard in
some other forms.
5. Everything must go somewhere.

• Consider the renewable and non-
renewable resources.
6. Ours is a finite earth.

• Human should take good care of the
nature we have and not will serve as the
destroyer.
7. Nature is beautiful and we are
the stewards of God’s creation

What is the difference between
environmentalist and ecologist?

ECOLOGIST ENVIRONMENTALIST
An ecologist is an environmental
expert who studies the environment
scientifically; moreover a scientist.
He has decent scientific knowledge
on natural environment and its
elements.
An ecologist usually work in the lab
but also outside in the fields. An
ecologist can examine things through
experiments and he is able to support
its preservation.
An environmentalist mostly examines
the natural environment through its
connection- interaction with human
(the human intervention on natural
environment, such as industry).
The environmentalist is the person
who is involved in relevant social
activities and focuses on the
importance of the environment of
human (pro-natural).
He is also a scientist that concentrates
most in observation, but he isn’t
working in labs by doing experiments
as the ecologist.

• WISE OLD MAN
• Once there was a wise old man. He was so wise he could answer any
question anyone ever asked him, no matter how difficult. One day, two
young people were talking and they said, “We're going to fool that old man.
We'll catch a bird, and go to the old man, and say, 'This that we hold in our
hands today, is it alive or is it dead?' If he says 'Dead,' we'll turn it loose and
let it fly, and if he says 'Alive,' we'll crush it.”
• So they caught a bird, and they carried it to that old man, and they said,
“This that we hold in our hands today, is it alive or is it dead?” And that wise
old man looked at those young people and he smiled. And he said, “It's in
your hands.”
