Mass
Why is water important to living things?
It is used in many biological processes and it is what most chemicals a dissolved in inside cells
It allows us to fully utilize nitrogen
Something has to offset the carbon dioxide we produce
It is hardly used in biological processes and is usually released as waste
Why is nitrogen important to living things?
It allows them to breath
It allows them to produce proteins
It allows them to produce more oxygen
it allows them to utilize all of the water they take in
Why is carbon important to living things?
It is one of the most important building blocks for life
Without it, we would not be able to produce pencils
It is needed for combustion reactions that keep living things warm
It isn't important carbon is kind of harmful and useless to living things.
A food web has arrows. The arrow shows:
The direction of energy flow (from predator TO prey)
The direction of energy flow (from prey TO predator)
The biomass at each trophic level
Possible feeding relationships
On average, this much energy from prey to predator is stored:
15%
5%
10%
100%
Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. Of the remaining energy, some is used for the organism’s life processes, and the rest is
