What changes the Carrying Capacity of a
population?

• Population Dynamics
• Abiotic Factors
• Biotic Factors

3
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.

4
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.

5
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. llanos dog
• eating his chickens.

6
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.

7
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.

8
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.

9
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.

10
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

11
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.

12
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.

13
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.

14
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 i
  nference which is important to recognize that
  these are very different things.

15
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.

16
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.

17
Carbon Dioxide Proximity to Land

• Helps the plants that are growing in the ground
  to photosynthesize.

18
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.

19
Phosphorous Proximity to Land

• It helps with the rock layers which help life uch
  as ATP and they make fossils happen.

20
Salinity Proximity to Land

• Salinity to land involves the salt continent in
  the soil.
• Salinity is the increase of salt in the dirt.

21
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.

22
Latitude Proximity to Land

• Latitude to land shows the land masses.
• For example mountains.

23
Temperature Proximity to land

• Temperature can affect the lands climate.
• For example it can be humid, hot, or cold due to
  temperature.

24
Underwater Topography Proximity to Land

• Underwater topography or the earths layers that
  exist on the shores and below the oceans surface.

25
Reduction in Biodiversity due to Catastrophic
Events

• Hurricanes
• Tornadoes
• Tsunami
• Earthquake

26
Reduction in Biodiversity due to Climate Changes

• Birds migrating to warmer climates while those
  who cant migrate die.

27
Reduction in Biodiversity due to Human Activities

• Cutting down trees for new houses.
• Pollution in lakes.
• Dumping trash on the beaches.

28
Reduction in Biodiversity due to Invasive

• People releasing their exotic animals into the
  wild.
• Introducing a new plant into
• the environment.

29
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.
