ABIOTIC AND BIOTIC
COMPONENT
Universal Solvent
Inorganic substance which
plays an important role in the
ecosystem.
It brings about changes in
the life forms of plants and
animals.
 Determines largely the character of vegetation and the types of
animals.
Types of Soil
1.
Loam
-Made up of particles of gravel sand and clay with the addition of
organic materials
2. Sand
-Inorganic soil particles those are larger than a clay or silt.
3. Silt
-Made up of very fine particles of soil and clay, deposited as
sediments.
4. Clay
-Smallest inorganic particle of soil compared with silt and sand. It
retains water before drying; it is sticky and not suitable for plant
growth.
 Light is an important physical factor. Without light, life
on earth would be impossible.
 The process of photosynthesis on which organisms
depend on the manufacture of food, does not take
place except in the presence of light.
 The character of the lightning of an area has a
profound effect on animals and plants that live there.
 Certain plants will thrive in the shade, whereas others
will not. This is likewise true of animals.
 Environmental temperature is an
important factor because of its
effect in metabolism.
 Temperatures in sunlight and in
shade differ and influence animals
in their selection of a habitat. The
effect of temperature on the
presence or absences of animals in
different habitat are varied.
 Types of animals in different body
temperature: Cold Blooded (fishes,
amphibians, reptiles) and Warm
Blooded (birds and mammals)
 Without oxygen, humans would not
be able to live. Oxygen is produced
by green plants through the process
of photosynthesis and is therefore
directly linked to sunlight.
Tropophytes
Mesophytes
PLANTS
Xerophytes
Hydrophytes
Halophytes
 These
plants that can
adapt it year after year
where seasonal changes
bring mark change in the
amount
of
available
water from the soil.
 Most
of
our
plants
bearing flowers and fruits
are
classified
as
mesophytes. They need a
moderate supply of water
for their subsistence.
 Plants that can tolerate where
water supply is very scantly.
HYDROPHYTES
 These
plants thrive in
places where the amount
of water is abundant:
usually fresh water plants
are called hydrophytes.
HALOPHYTES
 Plants thriving in a place where
the water available contains much
dissolved salts.
 The sea or oceans where plants
inhabit have abundant supply of
water,
but
due
to
its
concentration, the plant absorbs it
with difficulty.
Carnivore
ANIMALS
Herbivore
Omnivore
 Ectothermic
animal
with vertebrates that
are characterized by
scales,
fins
and
pharyngeal gills. There
are 3 main groups:
jawless,
cartilaginous
and bony. Ex. Lamprey,
dogfish shark, perch.
AMPHIBIANS
 Ectothermic
animal
with
vertebrates that are aquatic
as larvae and terrestrial as
adults. They breathe with
lungs as adults, have a moist
skin with glands and lack
scales and claws. Ex. Frog,
salamander, newt.
 Ectothermic
animal
with vertebrates that
have lungs, scaly skin
and a special type of
egg (amniotic). They
live entire life out of
water. Ex. Snake,
lizard, turtle.
BIRDS
 Endothermic, reptile-like
vertebrates
with
feathers, two legs used
for walking and perching
and wings that usually
don ’ t have claws. Ex.
Pigeon, hawk, eagle.
 Endothermic animals
with fur or hair, and
mammary glands that
produce
milk
to
nourish
young.
Almost all give birth
to live young. Ex.
Human, whale, fetal
pig.
