2. It is important in Science to be able to interpret and
convert everyday language read in texts into more
technical scientific language because technical language
helps communicate complex scientific ideas more
succinctly.

3. SHORT REVIEW
(7 MINS)
Q1. Name a living thing that
is not a plant or an
animal.
Q2. Name three important
things in your immediate
environment that are
abiotic.
Q3. Why do scientists use the
term “biotic” when they
talk about living things?
NLC | SCIENCE 7 | LESSON 7
4. The lesson is about the biotic and
abiotic features of an ecosystem.
We want to be sure YOU know and
understand the differences between
biotic and abiotic factors.

5. An ecosystem contains living
and non-living things. The
ecosystem has many examples
of the interaction between the
living and non-living.
A community of interacting
organisms and their
environment
DESCRIPTION
They include animals
(insects, birds, reptiles,
fish), plants, fungi,
protists and bacteria are
all biotic or living factors.
EXAMPLES

6. The living things in an
ecosystem are called biotic
factors.
All living things or their
materials that directly or
indirectly affect organisms in
its environment (includes
interactions)
DESCRIPTION
They include animals
(insects, birds, reptiles,
fish), plants, fungi,
protists and bacteria are
all biotic or living factors.
EXAMPLES

7. The non-living parts of an
ecosystem are called
abiotic factors.
Non-living components
that affect living
organisms
DESCRIPTION
They include water,
temperature, sunlight wind,
rocks or soil. Periodic
Disturbances –like fire,
volcanoes, hurricanes,
tornadoes

words that they are not familiar with and give
descriptions of any words that may be
problematic.

4B: LESSON ACTIVITY
Q1. Which label A, B or C on the
diagram shows where Jacob
would find crabs in the
mangroves?
Q2. Name the abiotic features of
a mangrove swamp
ecosystem shown in the
diagram.
Q3. If trees, like other plants,
need water, how do the
mangrove trees survive in salt
water?

Q1. What is the biggest threat to
the mangrove forests of the
Philippines?
Q2. What other abiotic factors
are a threat to the mangrove
swamps?
Q3. How do the mangrove
forests and swamps help protect
the biotic and abiotic features of
the Philippines?

CONCLUSION
(5 MINS)
Q1. Has this lesson helped you to
use more technical language
when talking about
ecosystems? If so, give an
example.
Q2. Has this lesson helped you to
remember and or understand
the differences between biotic
and abiotic factors in an
ecosystem? If so, how?
