when matter and energy moves through ecosystems
ecosystems energy flow
provides energy and food for the comsumers
producers
uses the product to function in ecosystems
consumers
name the 5 types of heterotrophs
herbivore
carnivore
omnivore
detritivore
decomposer
What is the difference between a detritivore and a decomposer?
Detritivores feed on plant and animal remains while decomposers break down the dead matter.
Name the 3 ecological methods
observing, experimenting, and modeling
list the levels of organization from smallest to largest
individual, population, community, ecosystem, biome, biosphere
list the levels of organization from largest to smallest
biosphere, biome, ecosystem, community, population, individual
What is the level that scientists study when observing, testing, and modeling
ecosystem
major land masses and groups of ecosystems that have the same climate and dominant communities
biome
Give some examples of biomes
tundra, tega, savanna, desert, tropical rain forest
contains the combined portions of the planet in which all life exists including land, water, air, or atmosphere
biosphere
a series of steps in which organisms transfer energy by eating and being eaten
food chains
what is the 3rd level consumer?
tertiary
connects all of the food chains in an ecosystem
food web
shows the relative amount of matter and energy
ecological pyramid
the rate at which organic matter is created by producers
primary productivity
ecosystem is limited by a single nutrient that is scarce or cycles very slowly
limiting nutrient
the result of an increased amount of limiting nutrients
algal bloom
any chemical substance that an organism needs to sustain life
nutrient
95% of the body is made up of these four elements
oxygen, carbon, hydrogen, and nitrogen
one organism is responsible for one change while another is responsible for the next
biogeochemical cycles
How does biogeochemical cycles help food chains?
if something cycles then it changes energy cycled through
what is the purpose of the water cycle?
all living systems need water
What are some of the steps for the water cycle?
evaporation, transpiration, condensation, precipitaion, runoff
liquid changes to a gas
evaporation
gas cools and changes to a liquid
condensation
water particles become too large to remain in Earth's atmosphere then they fall to Earth
precipitation
water runs down mountain
runoff
water penatrates soil
seepage
plants opens a structure and releases water
transpiration
nurtrients cyle through this cycle
nutrient cycle
what is the purpose of the carbon cycle?
to produce sugars
what is the chemical equation for photosynthesis?
6 CO2 + 6 H2O yields C6H12L6 + 6 O2
what is the purpose of the nitrogen cycle?
to produce proteins
what are the steps of the nitrogen cycle?
ammonification
nitrification
denitrification
when a dead organism is decomposed by decomposers an ammonia is released into the soil
ammonification
NH3 is oxidized into NO2 or NO3
nitrification
nitrogen is released into the atmosphere
denitrification
how can nitrogen become stable to where we can use it
lightening strikes
nitrogen-fixing bacteria
what is the purpose of the phosphorus cycle?
to make DNA and RNA
