Biology 301 MIDTERM EXAM Questions and Verified Answers/Accurate Solutions| New
Update Already Graded A+
Intra Same species
Inter Different species
Biotic living
abiotic Non-living
Population Same species living in the same area and interbreeding
Community populations that live together in a particular area
Ecosystem Multiple communities interacting with non living physical and chemical
environments
first law of thermodynamics Energy can be transferred and transformed, but it cannot be
created or destroyed. Can change form
Darwin's 4 postulates of natural selection variation, inheritance, born>survive, fitness
Producers Convert chemical energy (make)
Consumers Obtain energy (find)
Mixotrophs Can switch between consumers and producers
, Scavengers consume dead animals
Detritivores Break down dead organic matter into detritus
Mutualism both organisms benefit
Decomposers Breaks down detritus into smaller elements
Commensalism one organism benefits and the other is unaffected
Parasitism One organism benefits and the other is harmed
Niche Range of abiotic and biotic conditions an organism can tolerate
Hypothesis Ideas that potentially explain observation
Predication Statements that arise from hypothesis
Greenhouse gases Compounds that absorb infrared hear energy emitted but the earth and
then emit some back.
High amounts of greenhouse gases cause Increase in average earth temperatures
Requirements for evolution by natural selection More offspring are produced than survive,
variation, inheritance of variation, individuals with favorable characteristics are more likely to
survive and reproduce
