ecological organization & biomes
which level of organization has both biotic and abiotic factors?
ecosystem
(autotrophs) make their own food
Producers
Both species benefit from the relationship
Mutualism
Producers take in carbon dioxide and water to make glucose and oxygen.
Photosynthesis
succession
It extends from the crust of the Earth to the atmosphere and includes any part of the Earth where organisms live
Biosphere
(heterotrophs) have to consume or eat others for energy
Consumers
One species benefits by living in or on the other and the other is harmed
Parasitism
Consumers take in glucose and oxygen and release carbon dioxide into the atmosphere
Cellular respiration
occurs in an area never colonized (starts with bare rock)
primary succession
is made up of separate (but similar) ecosystems in a geographical area
Biome
They are moose and aphids, they eat plants
Herbivore
One species benefits and the other is neither helped nor harmed.
Commensalism
Bacteria change N2 gas into nitrates and ammonia that can be used in plants
Nitrogen fixation
Occurs when an area was disturbed (aleardy has soil)
secondary succession
Is a diagram that shows the relative amounts of energy or matter contained within each trophic level in a food chain or web
Ecological pyramid
They are lake trout and wolf, they eat meat
Carnivores
occurs when one organism (the predator) captures and eats another (the prey)
Predation
Bacteria convert nitrates to N2 gas to be released back into the environment
denitrification
cased by adding nutrents (nitrogen and phosphorous) to water from fertilizer or sewage
Agricultural runoff/ eutrophication
is the study of interactions among organisms and between organisms and their environment
Ecology
They are humans and bears, they eat plants and meat
Omnivores
when organisms use the same resource
Competition
what are the tree forms matter can be turned into
Carbon/oxygen cycle, Nitrogen cycle, water cycle
The Earth’s atmosphere is made up of gases such as water vapor, carbon dioxide, nitrous oxide, and methane. (greenhouse gases)
Greenhouse effect
