(21 cards)
Where is the most energy avalible on the prymid?
The producer or the bottom level
Where is the least amount of energy on the prymid?
The fourth level consumer or the top level
What is the order in witch the prymid goes in??
Producer, First level consumer,second level consumer,third level consumer and then fourth level consumer
What percent of energy is trasnferred to the next level in the energy prymid?
10%
What happens to the rest of the energy not transferred to the next level in an energy prymid?
Hydrogyn (6h20) and Carbon (6co2) is being USED by the plants and Glucose (c6h12o6) and oxygen (602) are being produced
What is the cellular resparation equation
6h20+6co2=c6h1206+602
The main source of energy
the sun
Where is the least amount of biomass
At the top of the prymid
where is the most amount of biomass
At the bottom of the prymid
The total amount of matter remains constant in a food web
Mass remains constant overtime
mass cannot be created or destroyed
mass can be transferred to one form to another
Where is the most amount of populations?
Producer or bottom of prymid
where are the least amount of populations?
Top or Fourth level consumer
What is the definition for the word Producer
An organism that makes its own food
what is a Decomposer?
An organism that breaks down wastes and dead organisms
what is a consumer?
an organism that obtains energy by feeding on other organisms
what is an energy prymid?
shows the amount of energy that moves from one feeding level to another in a food web
what is photosynthesis
the use of light energy to make food and converts light energy into chemical energy
what is a chloroplast?
plant cell organelle that contains chlorophyll and captures light energy into sugar
what is cellular respiration
the process in witch breaking down food molecules to get chemical energy for cell functions
what is a mitochondrion?
organelle found in most cells preform respiration and energy production
what is biomass
the amount of living matter in a given habitat
