What changes the Carrying
Capacity of a population?

Population Dynamics

Abiotic Factors

Biotic Factors
What does Population Dynamics
mean?

The factors involved in their maintenance,
decline, or expansion or the sequence of
population changes characteristic of a
particular organism.
What does Abiotic Factors mean?



A non-living chemical or physical factor in
the environment and may be group as
Climatic Factors- include sunlight,
humidity, temperature.
Edaphic Factors - include the nature and
type of the soil, geology of the land.
What is Biotic Factors?

A factor created by a living thing or any
living component within an environment in
which the action of the organism affects the
life of another organism, for example
a predator consuming its prey.

Ex- Mr. llano’s dog
eating his chickens.
How does Population Dynamics, Abiotic factors, and Biotic
factors change effect the population size in a ecosystem?

In long story short population dynamic is
the size of the population

Abiotic Factors shows how the area of the
animals environment is like.

Biotic factors show how predation rate
between different animals.
Organisms within a aquatic system due to
chemistry

Life as we know it started as a chemical
reaction, the synthesis of amino acids in
the primordial soup and ever since then
chemistry has been involved in all aspects
of life on our planet for example fish,
plankton or krill's.
Organisms within a aquatic system due to
Geography

Sharks like to live in warm oceans so they
can mate with other sharks and have their
pups feed off small fish that live nearby.
Organisms within a aquatic system due to Depth.

The deep-sea angler, a small black fish
with long, sharp teeth has live deep in the
ocean for so many years that if we were to
bring it to the surface it would die because
its body will expand due to the lack of
pressure.
Organisms within a aquatic system due to Salinity.


Organisms like the bull shark lives in saline
areas meaning it can lives in freshwater
that has been mix with salt.
They live like this in order to breed young
pups
Potential changes to an ecosystem from climate change.


Climate is an important environmental
influence on ecosystems.
For instance, warming could force species
to migrate to higher latitudes where
temperatures are more suited to their
survival.
Positive consequences that result from a
reduction in biodiversity.

A group of deer who are about to go extinct
lost their predator so their population
dramatically grew at a rapid pace.
Negative Consequences that result
from a reduction in biodiversity.

A group of trees in a forest was cut down
and all of the small helpless animals who
live in those trees had no protection to their
predator which lead to there extinction.
Scientific Standards

The processes of science include the formulation of
scientifically investigable questions, construction
of investigations into those questions, the collection of
appropriate data, the evaluation of the meaning of those
data, and the communication of this evaluation.

Scientific argumentation is a necessary part of scientific
inquiry and plays an important role in the generation and
validation of scientific knowledge.

Scientific knowledge is based on observation and inference
which is important to recognize that these are very different
things.
pH Proximity to Land

Soil pH or soil reaction is an indication of
the acidity or alkalinity of soil and is
measured in pH units.

It is use to help with farmers crops involving
the plants nutrients.
Oxygen Proximity to Land

Oxygen basically is from the plant
department as you should know I hope that
plants make oxygen and support the life
around it.
Carbon Dioxide Proximity to Land

Helps the plants that are growing in the
ground to photosynthesize.
Nitrogen Proximity to Land

Nitrogen is an element. It is found in living
things like plants. It is also an important
part of non-living things like the the dirt
below.
Phosphorous Proximity to Land

It helps with the rock layers which help life
uch as ATP and they make fossils happen.
Salinity Proximity to Land

Salinity to land involves the salt continent in
the soil.

Salinity is the increase of salt in the dirt.
Depth Proximity to Land

Depth to land is how deep it is.

For example the man made beach has
sand 12 feet high from the dirt.
Latitude Proximity to Land

Latitude to land shows the land masses.

For example mountains.
Temperature Proximity to land

Temperature can affect the lands climate.

For example it can be humid, hot, or cold
due to temperature.
Underwater Topography
Proximity to Land

Underwater topography or the earths layers
that exist on the shores and below the
oceans surface.
Reduction in Biodiversity due to
Catastrophic Events




Hurricanes
Tornadoes
Tsunami
Earthquake
Reduction in Biodiversity due to
Climate Changes

Birds migrating to warmer climates while
those who can’t migrate die.
Reduction in Biodiversity due to
Human Activities



Cutting down trees for new houses.
Pollution in lakes.
Dumping trash on the beaches.
Reduction in Biodiversity due to
Invasive
People releasing their exotic animals into
the wild.
 Introducing a new plant into
the environment.

Reduction in Biodiversity due to
nonnative species


English ivy - can take over hillsides and
forests, and kill mature trees.
Dumping your goldfish into a local
pond/river will hurt the salmon population.
