These 2 factors cause a population to increase.

What are birth and immigration?

100

all members of one species living in a specific area

What is a population?

100

something that eats another organism for food

What are consumers?

100

when liquid water becomes water vapor

what is evaporation?

100

The process that moves carbon from the atmosphere to the biosphere

what is photosynthesis?

200

These 2 factors cause a population to decrease?

What is deaths and emigration?

200

all members of all species in a particular area

What is a community?

200
an organism that makes its own food

producer/autotroph

200

when water vapor becomes liquid water

what is condensation?

200

the combustion of these releases carbon dioxide into the atmosphere

what are fossil fuels?

300

During this stage, a population's growth rate increases as the population grows.

What is exponential growth?

300

All living and nonliving things in a specific area

what is an ecosystem?

300

something that eats both plants and animals

what are omnivores?

300

water stored underground

what is groundwater?

300

The process in which atmospheric nitrogen is converted to ammonia

what is nitrogen fixation?

400

the maximum population an ecosystem can sustainably support

What is carrying capacity?

400

a biome that is characterized by high daytime and low nighttime temperatures and low levels of precipitation

What are deserts?

400

organisms that eat meat from organisms that are already dead, rather than hunting

what are scavengers?

400

when plants release water vapor through pores in their leaves called stomata.

What is transpiration?

400

bacteria that convert nitrogen compounds in the soil back into atmospheric nitrogen

denitrifying bacteria

500

these cause carrying capacity

what are limiting factors?

500
a group of ecosystems characterized by similar climates

what are biomes?

500

organisms that chemically break down organic matter

what are decomposers?

500

when water from precipitation goes downhill into a waterbody

what is runoff?

500

the conversion of nitrogen from dead organisms or waster into ammonia or ammonium

what is ammonification?
