Food webs
What makes up a food web?
Multiple food chains
What is the formula for cellular respiration?
Glucose and Oxygen = CO2 and H2O
What is the formula for photosynthesis?
H2O and CO2 and UV = Glucose and Oxygen
What is the 10 percent rule?
Only 10 percent of an organism's energy is given to the animal that consumes it.
Define biotic
The living components of an ecosystem.
What is the tertiary trophic level in a food web?
The organisms that prey on secondary consumers in the food web.
Do plants use cellular respiration?
Yes!
What is the primary source of energy on Earth?
The sun
Define omnivore
An organism that eats plants and animals
Define reactants
What you begin a chemical reaction with
What are producers and where are they located on the food web?
Producers create their own energy, mostly from sunlight, water and CO2 (photosynthesis), and they are located on the very bottom of the food web.
Why do we use cellular respiration?
Cellular respiration provides living organisms with an energy supply.
Who uses photosynthesis?
Producers (autotrophes)
Define herbivore
An animal that only eats non-meat food sources.
Define product
What you end up with after the chemical reaction
What is a consumer and where is it on the food web?
A consumer is any organism that feeds off another for energy and are usually located above producers on a food web.
What types of organisms use the process of cellular respiration?
Autotrophs and heterotrophs
Why do plants use photosynthesis?
Plants use photosynthesis to convert sunlight into glucose that can be transferred into energy.
Define ecosystems
A community of living organisms and their environment.
Define a trophic level
An organisim's place in a food chain or web
What are decomposers and where are they on the food web?
Decomposers feed on dead animals and are located on the outside of the food web linking the top trophic level back to the producers.
What products of photosynthesis is used during cellular respiration?
Glucose and oxygen
What products of cellular respiration are recycled into the photosynthesis cycle?
CO2 and H2O
Define abiotic
The non-living parts of an ecosystems.
Explain how the oxygen cycles through our fish tank experiment
The plant takes in CO2 and H2O to produce oxygen and glucose which are used by the fish to create H2O and CO2, the plant then uses the CO2 and H2O to repeat the cycle.
