components of ecosystem Flashcards
geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
ecosystem
community or group of living organisms that live in and interact with each other in a specific environment
ecosystem
factors under abiotic components
climatic and edaphic
climatic factors
rain, light, wind, temperature
edaphic factors
soil, pH, Minerals, topography
under biotic components
producers (autotrophs) consumers (heterotrophs) decomposers (saprotrophs)
consumers
primary, secondary, tertiary, quartenary
non-living components that shape its environment
abiotic
examples of abiotic factors
soil, temperature, light intensity, humidity of air, topography, etc.
mostly made up of small particles of rocks and it affects the distribution of organisms
soil
it affects the biochemical runs in the organism.
temperature
this will affect the distribution of plants, and therefore the distribution of animals that eat plants
light intensity
it refers to the lay of the land. it affects soil fertility with increasing fertility from ridge to valleys, because of soil erosion processes and matter transport
topography
it means living and in general capable of reproduction
biotic
biotic factors
bacteria, animal, plants, fungi, archea, protists
the living organisms in the ecosystem (3 groups)
producers, consumers, and decomposers
green plants, can carry out photosynthesis to produce food
producers
feed on plants and other organisms (herbivores, carnivores, omnivores)
consumers
bacteria and fungi that break down dead plants and dead animals into simple substances
decomposers
primary producers
plant phytoplankton
primary consumers
herbivore zooplankton
secondary, tertiary, quaternary consumers
carnivore carnivore
is any factor that places an upper limit on the size of a population. it can be biotic such as availability of food, or abiotic, such as access to water
limiting factor
these factors influence a specie’s ability to survive.
