 1.
tell what abiotic factor is
 2. give some examples of abiotic
factors
 3. work in learning centers dealing
with biotic and abiotic factors of the
environment
VOCABULARY WORD : MONDAY
ABIOTIC FACTOR
 Abiotic
factors are all of the nonliving
parts of an ecosystem.
 Sentence.
The abiotic factors of an
ecosystem, like air, water, and sunlight,
are influential factors of an ecosystem
that are not alive.
 Your
turn!
New Concept : Monday

The world contains a wide diversity of physical
conditions, which creates a wide variety of
environments: freshwater, marine, forest,
desert, grasslands, mountain, and others.

In any particular environment, the growth and
survival of organisms depend on the physical
conditions.
Vocabulary Word : Tuesday
Biotic Factors

Biotic factors are all of the living parts of an
ecosystem.

Sentence . The prefix bio- means life. Therefore ,
biotic means living. In an ecosystem, the biotic
factors are those factors that are alive, such as
plants and animals.

Your turn!
New Concept : Tuesday


Environmental factors that affect an organism's
ability to survive in its environment, such as
food availability, predators, and temperature,
are limiting factors.
A limiting factor is any biotic or abiotic factor
that restricts the existence, number,
reproduction, or distribution of organisms.
Vocabulary Word : Wednesday
Biome

Biome is a major ecological community such as
grassland, tropical rain forest, or desert

Sentence. The area you live in is a biome. Large
areas such as desert, Arctic and rain forest, are
different biomes.

Your turn!
New Concept : Wednesday

At high elevations, temperatures are too low, winds too strong and
the soil too thin to support the growth of large trees. Vegetation is
limited to small, shallow-rooted plants, mosses, ferns and lichen.

Factors that limit one population in a community may also have an
indirect effect on another population.

Lack of water could limit the growth of grass in grassland, reducing
the number of seeds produced. The population of rabbits
dependent on those seed for food will also be reduced and the
hawks depending on the rabbits will be reduced too as a result of a
decrease in their food supply.
New Concept : Thursday

Another factor for survive is the ability of an organism
to withstand fluctuations in biotic and abiotic
environmental factors.

The limits of an organism's tolerance are reached when
the organism receives too much or too little of some
environmental factor. Organisms become fewer as
conditions move toward either extreme of the range of
tolerance (too much or too little).
