Interdependence And Human Impacts Flashcards
A relationship between organisms where there is a cycle where one’s population increases, and the other follows, then one decreases and the other follows.
Predator/Prey Relationship
What happens when two species occupy the same niche at the same time?
Competition
Three types of symbiosis
Commensalism, Mutualism, Parasitism
Commensalism
One organism benefits and the other is unaffected
Parasitism
One organism benefits and the other suffers
Mutualism
Both organisms benefit from
Light, food, fuel, medicine, building material, paper, and soil are all…
Resources provided by the ecosystem
What is poaching?
The process of hunting and illegally killing endangered animals
What are some reasons you might NOT want to save a plant?
Money, funding, if it can survive in a lab, etc…
Alternate energy
Solar, wind
Hot spots
The places that are most endangered and where investing money will have the greatest impact
Anthrome
Human impacted biomes
Ecological instability
The result in an ecosystem becoming less diverse
What gas becomes abundant due to deforestation
Co2
What gasses are responsible for the destruction of the ozone layer and global warming?
Methane and Co2
Symbiotic relationship
A close, prolonged interaction between two or more different species
Habitat fragmentation
When parts of a habitat are destroyed, leaving behind similar disconnected pieces
Greenhouse effect
The process through which heat is trapped near Earth’s surface by greenhouse gases.
What chemical causes ozone depletion
CFC
Fossil Fuels
The fuel that comes from the remains of organisms from years ago
What results from splitting atoms
Nuclear Fuel
Industrialization
The process of turning an economy from one that depends on agriculture to one that depends on manufacturing
What are the three Rs
Reduce, Reuse, and Recycle
List the levels of organization from smallest to largest
Individual, Population, Community, Ecosystem, Biome, Biosphere
The more stable an ecosystem is…
The more biodiverse it is
Three types of pollution
Water, air, soil
Photosynthesis takes _______ out of the atmosphere
Co2
_________ traps heat
Co2
Carrying Capacity
The maximum population of a certain species that an environment can hold
What determines carrying capacity
Limiting factors
Renewable Resources (list three)
Resources that can be replenished (food, water, trees)
Non-renewable Resources (list three)
Resources that cannot be replenished (aluminum, coal, iron)
Trade-off definition
Pros and cons to doing something but the pros outweigh the cons (ex: building on land could kill some organisms but it would create many job opportunities)
Monoculture
Planting large areas with a single highly productive crop year after year… may degrade soil over time
Acid Rain
Results when nitric and sulfuric acids are formed after being released by the burning of fossil fuels in our factories and homes (effects ecosystems)
