water enters the atmosphere in a form called water vapor

biome- large group of ecosystems that share the same climate and have similar types of communities

organism that gets its energy requirements by consuming other organisms

symbiotic relationship in which one organism benefits and the other organism is neither helped nor harmed

trophic level

name 4 biotic factors

abiotic factor- any non-living factor in an organisms environment

most of the earths nitrogen is found in the atmosphere

heterotroph that preys on other heterotrophs

organisms ability to survive biotic and abiotic factors. as the larger body becomes less responsive to a drug, an-

any living factor in an organisms environment

matter- anything that takes up space and has mass- provides the nutrients needed for organisms to function

clouds form when water vapor rises, cools and condenses into droplets around dust particles in the atmosphere

heterotroph that decomposes organic materials and returns the nutrients into soil air etc making it available to organis

chemical substance that an organism must obtain from its environment to sustain life

biosphere

plants and animals/ energy and lightning: living and non-living parts of the...

process in which fixed nitrogen compounds are converted back into nitrogen gas and returned to the atmosphere

food web-model that shows many interconnected food chain and pathway in which energy and matter flow through an ecosyste

all the interacting populations of different species that live in the same geographic location at the same time

food chain- simplified model that shows a single path for energy flow through an ecosystem

ecosystem

four important biogeochemical processes that cycle matter

what does the biosphere include?

name 4 abiotic factors:

act of one organism feeding on another organism

energy from the sun causes water to constantly evaporate from the earths surface

role or position of an organism in its environment

bacteria and other microorganisms perform nitrogen fixation

biogeochemical cycle- the exchange of matter through the biosphere

organism, population, biological community, ecosystem, biome, biosphere

name the basic needs of an organism

mutualism

nitrogen fixation- process in which carbon gas is captured and converted into a form plants can use

parasitism- symbiotic relationship in which one organism benefits at the expense of another organism

the scientific discipline in which the relationships among living organisms and the interaction the organisms have with-

heterotroph that eats plants

biotic or abiotic factor that restricts the number, distribution, or reproduction of a population within a community

symbiosis- close mutualistic, parasitic or commensal association between two or more species that live together

heterotroph that consumes both plants and animals

one example of 1. competition and 2. predation

population- group of organisms of the same species that occupy the same geographic place at the same time

an organism that collects energy from sunlight or inorganic substances to produce food

physical area in which an organism lives

difference between a habitat and a niche:

scientists that perform tests to determine relationships among groups of organisms and environmental factors
