define biotic and abiotic
biotic= all livings organisms
abiotic= non-living things
define interspecific competition
competition between species
what makes up food chains?
trophic levels
mutualism, parasitism, communalism
define tradeoff
the cost of producing a genetic advantage
what do primary consumers eat?
producers
what does low resources cause in terms of interactions and competition
more interactions and more competition
carbon cycles through what?
biomass, air, water, and rocks
how does competition relate to adaptation
any genetic advantage makes it easier to win in competition, therefore making it more likely to reproduce and pass on traits
define energy
the ability to do work
air, water, the sun, rocks and minerals
define intraspecific competition
competition within species
A food web has overlapping food chains that show what in an ecosystem
flow of energy
how is herbivory similar to predation
it helps control the population of plants and reduces competition with and among plants
define facultative
both organisms can live without each other
what does a secondary consumer eat?
primary consumers
what does high resources cause in terms of interactions and competition
less interactions and less competition
what has to be turned into ammonia before being cycled
nitrogen
define obligate
one or both organisms cannot live without each other
true or false: a dependent interaction is when an animals work together to survive
false
explain how population relates to intraspecific competition
populations consist of one species so when they compete it's intraspecific completion
define competition
interactions between organisms in which one organisms gains a limited resource at the expense of the other
define a producer
an organism that transforms energy from the sun water and c02 to make food
what does it mean for a competitive advantage to be frequency dependent
a trait will be more advantageous if it is rare and less advantageous if it is common
explain the difference between the phosphorus and nitrogen cycle
nitrogen has to be turned into ammonia before it can be cycled. phosphorus is cycled as is
