Chapter 5 + 6 - Populations by Anastasia Hall https://padlet.com/2023halla1/rljvzbxr5a3cak41 Final Exam Task en-us 2021-05-12 18:07:18 UTC 2023-03-12 16:19:34 UTC hello@padlet.com Key Terms 2023halla1 https://padlet.com/2023halla1/rljvzbxr5a3cak41/wish/1518667980 -Density: The degree of compactness of a substance; the number of organisms per unit of area
-Logistic growth: The population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
-Carrying capacity: The number or quantity of people or things that can be conveyed or held by an environment or container. -Limiting factor: A factor that causes population growth to decrease.
-Biodiversity: The sum total of the genetically based variety of all organisms in a biosphere.
-Growth rate: The percentage change of a specific variable within a specific time period.
-Exponential growth: Growth whose rate becomes ever more rapid in proportion to the growing total number or size; happens when there is unlimited resources/space.
-Pollutants: Harmful material that can enter the biosphere through land, air or water.
-Species: Group of similar organisms that can breed and produce fertile offspring.
-Invasive species: Introduced species that rapidly reproduce because their new habitat lacks the predators that would otherwise control their population.]]> 2021-05-12 18:11:38 UTC https://padlet.com/2023halla1/rljvzbxr5a3cak41/wish/1518667980 Additional Information 2023halla1 https://padlet.com/2023halla1/rljvzbxr5a3cak41/wish/1518713852
  • Exponential Growth graphs (J-shaped) occurs when there's an abundance of food in space which makes the line increase quickly. Logistic growth graphs (S-shaped) are when population decreasing when food is short, then reaches carry capacity which starts to level off.
  • The Wolf and Moose population on Isle Royale graph shows a predator-prey relationship. It shows when there is an increase in prey there is less predators, so when there is an increase in predators there is less prey. 
  • To keep population at a carry capacity there is a birth and death equality, which is a growth rate of 0. Another way to keep population at capacity is because there won't be enough food which causes a decrease of animals.

    -The population density is the number of individuals in one area and population distribution is how the organisms are spaced out in the habitat.

    2.What causes exponential growth to occur? 
    -It occurs when organisms have been provided with unlimited resources and space, with a lack of predators.

    3.What will happen if a population exceeds carrying capacity?
    -The population will run out of food and decrease.

    4.What is the difference between renewable and nonrenewable resources?
    -Renewable resources can be renewed, you can keep getting them. A nonrenewable resource you can’t get again, cannot be renewed.

It explains the life of animals and how they will survive. It describes how animals keep their balance in natural, for example, not an over abundance of one animal. This is important to know about so us, humans, don't have a population extinct. ]]> 2021-05-13 03:07:16 UTC https://padlet.com/2023halla1/rljvzbxr5a3cak41/wish/1519980207
