Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...

The study of how organisms interact with one another and with their nonliving environment is - ecology In a deciduous oak forest in the northeastern United States, one example of a nonliving component of the ecosystem is - sunlight that filters through the canopy A population grows exponentially when - the birth rate exceeds the death rate and immigration exceeds emigration. The different species within an ecosystem that interact in various ways make up a(n) - community All members o...
