Flashcards covering types of technology and their environmental impacts, human influence on ecosystems, ecological interactions like symbiosis and competition, niches, and characteristics of living organisms.
what are the 3 types of technology mentioned, and positive and negative outcomes of each?
AGRICULTURAL technology: goal is to increase food productivity
pros: contour farming, fertilizers, irrigation systems, farm machines
cons: fertilizers lead to excess nitrogen in the soil, farm machinery run on fossil fuels
ALTERNATIVE ENERGY technology: the goal is to provide “clean” energy to power society without negatively influencing the atmosphere
pros: decreases the burning of fossil fuels, uses renewable resources
cons: expensive, and nuclear energy creates radioactive waste
INDUSTRIAL technology: goal is to increase manufacturing efficiency, transportation, and communication
pros: improved communication, faster transportation, and cheaper industries
cons: CFCs (chlorofluorocarbons) are created, greenhouse gases released, acid rain

how can humans impact the process of ecological succession?
they can help plant seeds, moss, or lichens or create a situation where secondary succession will occur
what is the difference between predation and parasitism?
predation: one animal kills and eats another for food
parasitism: a type of symbiotic relationship where 1 organism (the parasite) benefits from...
what is the difference between interspecific competition vs intraspecific competition
interspecific is competition between organisms of different species
intraspecific is where competition is occurring within the same species
define symbiosis
any interaction that involves a close, physical, long term relationship- one species always benefits, and its always between 2 different species
what are all the types of symbiotic relationships, and what are their definitions?
Parasitism: one organism benefits from the relationship while the host is harmed
commensalism: one organism is benefitted while the other is una...
