Your diagram can be simple, just remember that
A and G are double rings; C and T are single rings.

Bases are the “rungs of the ladder”
hydrogen bonds between bases are in very center

involved.

and the biosphere (you could substitute the
through processes word “fossilization” for
of photosynthesis, “calcareous sediments” above
respiration, -combustion (burning of fossil
fossilization & fuels)
combustion

4.2.2 Draw a graph showing the sigmoid (S-shaped)
population growth curve
*you could use “organisms” or “population
size” for the Y axis as well.

starts slow, rises exponentially, then
plateaus at the carrying capacity of the
environment
