Introduction
The Condor, is an important animal, People have damaged most of the condor population.Th
e condor population is in constant decay
If the condor population keeps this constant decay, will it get to the point of
extintion
?Slide3
The Condor
Since 2000, the Condor populations have declined,
This is a endangered species
There are only about 50-65 Condors left in Ecuador.
causes for the decay of Condors.
In 2009 an organization dedicated to the protection of the Condor was created.
The Condor is a Monogamous animal, and it can only lay one egg a year.Slide4
In 2002, Aves & Conservación stated that there were no more than 70 individuals.
The Andean Condor is considered a threatCondors, are scavengers, they only eat dead animals.The first condor census was made in 1991 and 200 condors were registered.The condor is the biggest flying land bird in the world.Slide5
Math
Lab-Decay
Has the Condor population in
ecuador
been decreasing constantly in the last couple of years?
Used
the table with data for several years (1991-2014) of the condor pop
Calculated the
df
for each pair of values in the table by dividing a value by the previous one
We obtained 4 different
df
Avg
those
With initial
amnt
and
df
wrote the equationSlide6

Goats
infoFeral goats are known because of their big appetite and because, they eat everything
They are devastating for some sectors, and in many plagues, they are considered plagues.
Many people have to search for a harsher way of dealing with them, for example hunting, poisoning, tracking, etc.Slide8

goats in Galapagos
Used
initial and final number of goats in
Pinta
(3 in 1959 and 20,000 in
1971)
Created a table with those
values
Approximated a growth factor (with calculator) for the 12 years (2.083)Filled the table by multiplying each value by the gf to get the next valueUsed initial amount and gf to write the equationSlide9

Conclusion
A
s a conclusion we have realized that if we continue growing down this exponential decay path , the condor could be extinct in a few decades in fact in five years from now there are only going to be 36 condors
P=200(.71
5
)= 36
This all means that by the year 2020 there could only be 36 condors left in Ecuador
