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

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 the relationship while the host is harmed

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 unaffected
mutualism: both organisms involved benefit, and the relationship helps both organisms survive
what is a niche?
the specific role of an organism in its community
what is the competitive exclusion principle?
no two organisms can occupy the same niche at the same time, so they will compete, and the better one will take over
