SC.912.L.17.5 By: Ruben Garcia
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 ecosystemfrom 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.
