population growth
These 2 factors cause a population to increase.
What are birth and immigration?
all members of one species living in a specific area
What is a population?
something that eats another organism for food
What are consumers?
when liquid water becomes water vapor
what is evaporation?
The process that moves carbon from the atmosphere to the biosphere
what is photosynthesis?
These 2 factors cause a population to decrease?
What is deaths and emigration?
all members of all species in a particular area
What is a community?
producer/autotroph
when water vapor becomes liquid water
what is condensation?
the combustion of these releases carbon dioxide into the atmosphere
what are fossil fuels?
During this stage, a population's growth rate increases as the population grows.
What is exponential growth?
All living and nonliving things in a specific area
what is an ecosystem?
something that eats both plants and animals
what are omnivores?
water stored underground
what is groundwater?
The process in which atmospheric nitrogen is converted to ammonia
what is nitrogen fixation?
the maximum population an ecosystem can sustainably support
What is carrying capacity?
a biome that is characterized by high daytime and low nighttime temperatures and low levels of precipitation
What are deserts?
organisms that eat meat from organisms that are already dead, rather than hunting
what are scavengers?
when plants release water vapor through pores in their leaves called stomata.
What is transpiration?
bacteria that convert nitrogen compounds in the soil back into atmospheric nitrogen
denitrifying bacteria
these cause carrying capacity
what are limiting factors?
what are biomes?
organisms that chemically break down organic matter
what are decomposers?
when water from precipitation goes downhill into a waterbody
what is runoff?
the conversion of nitrogen from dead organisms or waster into ammonia or ammonium
what is ammonification?
