Front 1

What does CHONPS stand for

Back 1

CHONPS is the order of the most concentrated elements in your body (Carbon, Hydrogen..)

Front 2

What percent of your body is made up of trace elements.

Back 2

2-4%

Front 3

How does calcium benifit the body?

Back 3

- helps keep bones strong
- helps muscles contract
- helps nerves send messages to the brain

Front 4

How does selinium help the body?

Back 4

prevents blood clots

Front 5

red blood cells are refered to as

Back 5

Erythrosytes

Front 6

define ecosystem

Back 6

community and all the non-living parts

Front 7

define community

Back 7

diff. populations that live together

Front 8

define population

Back 8

individuals of the same species living together

Front 9

define ecology

Back 9

studying the relationship of organisms with each other and the enviornment.

Front 10

define watershed

Back 10

an area where all the precipitation flows into a single river or stream

Front 11

define niche

Back 11

a specific job an organism has

Front 12

heterotroph

Back 12

any organism that cannot produce their own food. they must feed on other organisms for energy,

Front 13

The three main parts of ATP are..

Back 13

1) base - CN double rings
2) rhybos - 5 Carbon sugar
3) 3 Phosphate ions held together with high energy bonds.

Front 14

What makes energy in your body

Back 14

mitochondria

Front 15

define autotroph

Back 15

organism that can prode its own food through photosynthesis (plants)

Front 16

define trophic levels

Back 16

different levels of feeding relationships

Front 17

define primary producers

Back 17

the trophic level that ultimitly supports all others in an ecosystem (autotrophs)

Front 18

define primary consumers

Back 18

herbivores, which eat the primary producers

Front 19

define secondary consumers

Back 19

carnivores, which eat herbivores (primary consumers)

Front 20

define tertiary consumers

Back 20

eat the secondary consumers

Front 21

define Detritivores

Back 21

organisms that derive energy from detrititus

Front 22

define detrititus

Back 22

nonliving organic matter, such as feces, fallen leaves (emo kids), the remains of dead organisms

Front 23

define food chain

Back 23

the pathway along which food is transferred from trophi level to trophic level, beninnign with primary produers

Front 24

define production

Back 24

the rate of incorporation of energy and materials into the bodies of organisms

Front 25

define consumption

Back 25

refers to the metabolic use for growth and reproduction of assimilated organic materials.

Front 26

define decomposition

Back 26

the third ecosystem process, the breakdown f organic materias into inorganic ones

Front 27

define primary productivity

Back 27

the amount of light energy converted to chemical energy by the autotrophs of an ecosystem during a given time period.

Front 28

define gross primary productivity

Back 28

total primart productivity

Front 29

net primary productivity

Back 29

GPP-energy used by the producers for respiration

Front 30

biomass

Back 30

promary productivity expressed as a weight (energy per unit area per unit time = g/m^2/yr)

Front 31

define standing crop biomass

Back 31

total biomass of photosynthesetic autotrophs present at a given time

Front 32

define pyramid of productivity

Back 32

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

Front 33

define biomass pyramid

Back 33

a pyramid in which each tier represents the standing crop biomass in a trophic level

Front 34

pyramid of numbers

Back 34

a pyramid in which the size of each block is proportional to the number in individual organisms represented in each trophic level.
