Living organism in the environment
Biotic factor
Non living parts of the environment
Abiotic factor
A living thing
Organism
Eats meat and plants (humans)
Omnivore
the process by which the structure of a biological community evolves over time, the formation of a new community.
Succession
occurs in essentially lifeless areas- regions in which the soil is incapable of sustaining life as a result of such factors as glaciers, newly formed islands, or lava left from a volcanic eruption.
primary succession
occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment:
secondary succession
relationship in which one species lives on, in, or near another species and affects its survival
symbiosis
known for traveling on the HMS beagle and for exploring the Galapagos islands, and studying tortoises, iguanas, finches.
charles Darwin
type of symbiosis which both species benefit
mutualism
type of symbiosis in which one species benefits and the other species is neither harmed or benefited.
commensalism
type of symbiosis in which one species benefits and the other species is harmed.
parasitism
organisms that cannot make their own food and must eat other organisms
consumer
organisms that make their own food ( plants and some bacteria)
producer
eat plants (cows)
herbivore
eat meat ( wolves)
carnivore
1st species to appear as a result of succession
pioneer species
process that occurs when gases in the atmosphere trap the sun’s heat and makes the Earth’s temperature warm enough to sustain life
greenhouse effect
change/time
evolution
what type of organisms change nitrogen into a usable form of plants
bacteria
how does nitrogen get from the atmosphere to the ground
lightning
how does water get from the atmosphere to the ground
precipitation
how does carbon dioxide get into the atmosphere
burning fossil fuels
how does oxygen get into the atmosphere
plants release it into the atmosphere
