What does CHONPS stand for
CHONPS is the order of the most concentrated elements in your body (Carbon, Hydrogen..)
What percent of your body is made up of trace elements.
How does calcium benifit the body?
- helps keep bones strong
- helps muscles contract
- helps nerves send messages to the brain
How does selinium help the body?
prevents blood clots
red blood cells are refered to as
define ecosystem
community and all the non-living parts
define community
diff. populations that live together
define population
individuals of the same species living together
define ecology
studying the relationship of organisms with each other and the enviornment.
define watershed
an area where all the precipitation flows into a single river or stream
define niche
a specific job an organism has
any organism that cannot produce their own food. they must feed on other organisms for energy,
The three main parts of ATP are..
1) base - CN double rings
2) rhybos - 5 Carbon sugar
3) 3 Phosphate ions held together with high energy bonds.
What makes energy in your body
define autotroph
organism that can prode its own food through photosynthesis (plants)
define trophic levels
different levels of feeding relationships
define primary producers
the trophic level that ultimitly supports all others in an ecosystem (autotrophs)
define primary consumers
herbivores, which eat the primary producers
define secondary consumers
carnivores, which eat herbivores (primary consumers)
define tertiary consumers
eat the secondary consumers
define Detritivores
organisms that derive energy from detrititus
define detrititus
nonliving organic matter, such as feces, fallen leaves (emo kids), the remains of dead organisms
define food chain
the pathway along which food is transferred from trophi level to trophic level, beninnign with primary produers
define production
the rate of incorporation of energy and materials into the bodies of organisms
define consumption
refers to the metabolic use for growth and reproduction of assimilated organic materials.
define decomposition
the third ecosystem process, the breakdown f organic materias into inorganic ones
define primary productivity
the amount of light energy converted to chemical energy by the autotrophs of an ecosystem during a given time period.
define gross primary productivity
total primart productivity
net primary productivity
GPP-energy used by the producers for respiration
promary productivity expressed as a weight (energy per unit area per unit time = g/m^2/yr)
define standing crop biomass
total biomass of photosynthesetic autotrophs present at a given time
define pyramid of productivity
A graph in which the trophic levels are stacked in blocks, with primary producers forming the foundation of the pyramid. The size of each block is proportional to the productivity of each trophic level
define biomass pyramid
a pyramid in which each tier represents the standing crop biomass in a trophic level
pyramid of numbers
a pyramid in which the size of each block is proportional to the number in individual organisms represented in each trophic level.
