1. The monkey-eating eagle (Pithecophaga
jefferyi) is considered endangered
species due to its extremely low birth
rate.
2. In some places where access to
contraceptives are lacking and generally
low level
of female education, their fertility rates
are high.
.
3. Women give birth at a late age in places
where access to contraceptives is
sufficient.
4. The discovery of vaccines to some diseasecausing bacteria or viruses saves the
lives of many people from death.
5. Construction of dams, highways and
urbanization destroy the habitat of some
species.

• A (1) __________ is defined as a group of living
things within a certain area that are all of the
same species. Populations can be of the same
size, but they may have different (2) _________.
Population density is equal to the number of (3)
__________per unit area. The size of a population
is controlled by (4) __________ factors which are
categorized into two; the density-independent
limiting factors and the (5) __________ limiting
factors.

population from growing regardless of how many
organisms are living in a certain area. On the
other hand, availability of basic needs such as
foods, water, and oxygen are examples of

the growth of a population when their number is
already in the (8) __________ carrying capacity.

• These factors are dependent on the number of
organisms the environment is sustaining. The
maximum number that a particular environment
can support is called its (9) __________. Each
population of organism has different carrying
capacity, depending on the amount of resources
available in the area in which it lives. If the
population size (10) __________ above the
carrying capacity, some organisms die because
not all their needs are sustained or provided..
