the 5 ecological levels of organization are ORGANISM, POPULATION, COMMUNITY, ECOSYSTEM, BIOSPHERE
ORGANISM is any form of life which includes plants and animals
POPULATION is a group of organisms of the same species living within a particular area
COMMUNITY is the population of different plants and animals living and interacting in an area at a particular time
ECOSYSTEM is the community of organisms and populations interacting with one another and with the abiotic factor making up the environment
BIOSPHERE is the summation of all ecosystems worldwide
the 2 components of the environment are ABIOTIC FACTORS, BIOTIC FACTORS
the 7 abiotic factors are LIGHT ENERGY, WATER, ATMOSPHERIC GASES, WIND AIR CURRENTS, TEMPERATURE, SOIL, PHYSIOGRAPHIC FACTORS
LIGHT ENERGY is the photosynthetic activity of green plants with chorophyll
LIGHT ENERGY affects day length caused by circadian rhythm which is the rotation of the earth in its own axis nocturnal and diurnal organisms
WIND AIR CURRENTS carries water vapor which condense and fall as rain snow or hail
WIND AIR CURRENTS plays a role in plant pollination and seed dispersal
WIND EROSION removes and redistributes topsoil
TEMPERATURE affects the distribution of organism in the surface of the planet
TEMPERATURE is influenced by the revolution of the earth around the sun bringing about seasonal rhythm
TEMPERATURE affects activities of organism dormancy migration germination
SOIL TEXTURE supports different types of vegetation animals
SOIL TEMPERATURE affects organic matter decomposition
SOIL WATER SOLUTION PH influence biological activities and availability of certain minerals
PHYSIOGRAPHIC FACTORS affects the vegetation zones presence of sun or rain bearing winds and temperature of the soil surface
the 3 biotic factors AUTOTROPHS, HETEROTROPHS, DECOMPOSERS
AUTOTROPHS capture energy such as the sunlight and use it along with inorganic nutrients to produce organic compounds
AUTOTROPHS are producers
HETEROTROPHS need a source of preformed organic nutrients and consume tissues of other organisms
HETEROTROPHS are consumers
DECOMPOSERS are non photosynthetic bacteria and fungi that extract energy from dead matter including animal wastes in the soil and make nutrients available
the 6 nutritional relationships are COMPETITION, PARASITSM, PREDATION, COMMENSALISM, PROTOCOOPERATION, MUTUALISM
COMPETITION is the idea that two organisms utilizing the same environmental resource interspecific or intraspecific
PARASITISM is the idea that the parasite benefits at the expense of the host
PREDATION is the idea that a predator feeds on a prey
COMMENSALISM is the idea that the commensal benefits while the host is unaffacted
PROTOCOOPERATION is favorable to both but not obligatory
