Populations
Scientists who study human populations.
What are demographers?
These are autotrophs such as plants and algae.
What are producers?
This includes precipitation, transpiration, evaporation, and infiltration.
What is the hydrologic cycle?
Specific environment where an organism lives.
What is a habitat?
Found in Africa and Australia, these are dry tropical grasslands and trees.
What is the savanna?
Attributes of the environment that can restrict population growth.
What are limiting factors?
Zooplankton, insects and herbivores that eat producers.
What are primary consumers?
This includes use by plants and trees, fixation in soil by crops and bacteria, use by ocean algae, and conversion to ammonium to be used by plants.
Populations of different species living together in a particular area.
What is a community?
This includes coniferous trees, has a heavy rainfall, and found in the Pacific Northwest region of the US.
What is temperate rainforest?
The maximum population of a species an environment can support.
What is carrying capacity?
These animals that eat primary consumers.
What are secondary consumers?
This includes fossil fuel extraction, decomposition, plant respiration, and volcanic emissions.
What is the carbon cycle?
An organism's functional role in a community.
What is a niche?
Areas closer to the equator with high rainfall and greater biodiversity.
What is a tropical rainforest?
What is logistic growth?
These animals are on the highest tropic level and consume other animals.
What are tertiary consumers?
This includes sedimentary rock, detergents, uptake by plants, and decomposers.
What is the phosphorus cycle?
Timber, water, animal populations, wind.
What are renewable natural resources?
Found in India and South America with warm temperatures but seasonal rain fall.
What is tropical dry forest?
When a population increases by a fixed percentage every year.
What is exponential growth?
Amount of energy that is passed between consumers in a food web.
What is 10%?
This is what is cycled through producers, consumers, and decomposers.
What is energy?
Minerals and fossil fuels.
What are nonrenewable natural resources?
Has evergreen shrubs, highly seasonal, and at higher risk of wild fire.
What is chaparral?
