Chapter 9 - Interaction of Living Things Flashcards
ecosystem
the living and nonliving things in one place
biome
is a geographic area on Earth that contains ecosystems with similar biotic and abiotic features
carrying capacity
is the largest number of individuals of one species that an ecosystem can support over time
symbiotic relationship
is one in which two different species live together and interact closely over a long period of time
Types: mutualism, parasitism, and commensalism
biotic potential
is the potential growth of a population if it could grow in perfect conditions with no limiting factors
parasitism
a symbiotic relationship in which one species benefits and the other is harmed
commensalism
a symbiotic relationship in which one species benefits and the other is neither helped nor harmed
limiting factors
are factors that can limit the growth of a population
oxygen cycle
recycles gas in the atmosphere that people can breathe in
overpopulation
more individuals than an ecosystem can support
mutualism
a symbiotic relationship in which both species benefit from each other
carnivore
a consumer that eats only meat
herbivore
a consume that eats only plants
producers
change the energy available in their environment into food energy (plants)
energy pyramid
shows the amount of energy available at each step of a food chain
biotic factor
are all of the living or once living things in an ecosystem
abiotic factor
are the nonliving parts of an ecosystem
population
is made up of all the members of one species that live in an area
succession
is the gradual change from one community to another community in an area
community
is all the populations living in an ecosystem at the same time
habitat
the physical place where a population or organism lives
niche
is the unique ways an organism survives, obtains, food and shelter, and avoids danger in its habitat
