Population Dynamics
The number of births per per year in a specific population.
What is birth rate?
Non-living parts of the environment like water and air. AND give 3 other examples
What are abiotic factors? Temperature, Precipitation, Rocks, Amount of sunlight
Interaction where both organisms benefit.
What is mutualism?
Species that evolved to live in a specific ecosystem.
What are native species?
Graphic showing levels of organisms organized by energy and mass.
What is an energy/trophic pyramid?
The total number of individuals of a specific species in a specific area.
What is population?
Living parts of the environment, including plants and animals.
What are biotic factors?
Interaction where one organism benefits and the other is unaffected.
What is commensalism?
Species that move into a new ecosystem and compete with native species.
What are invasive species?
Consumer organisms that break down dead material and return matter to the food web.
What are decomposers?
The largest number of individuals an ecosystem can support.
What is carrying capacity?
All living and nonliving parts of an area that interact.
What is an ecosystem?
Interaction where one organism benefits and the other is harmed. - Give 1 example
What is parasitism? Tick and dog
Destruction of natural ecosystems needed for survival.
What is habitat destruction?
The amount of energy and mass __________ as you go up the trophic pyramid.
What is decreases?
Factors like food, water, and space that prevent population growth.
What are limiting factors?
What is the biotic factor where organisms both need the same resources?
What is competition?
The animal that hunts and eats another animal.
What is a predator?
Harvesting too many individuals (could be plants or animals), leading to population decline.
What is overharvesting?
The base level of the trophic pyramid consists of these organisms.
What are producers?
When a new predator is introduced the population of prey animals will most likely do this.
What is go down?
The type of relationship that is most likely to occur between a secondary consumer and a primary consumer.
What is predation?
This is why Biodiversity is important.
What is reduces is the impact of negative factors of ecosystems and allows them to be more resilient to change.
These are some things that humans can do to reduce the impacts on Biodiversity:
Answers will vary (Eliminate invasive species, legally protect habituate, find alternative sources of energy)
What is the relationship between being higher on the trophic level and the number of individuals of in a population.
What is the higher on the trophic level, the less energy flows up and therefore less individuals of a species can be supported.
