Organisms need energy to survive. Energy from the sun flows into and
out systems. This energy drives our world and the organisms in it.
Energy is lost “not destroyed” when it changes form. Flows Hot to Cold

• Which tree has more value in a forest
ecosystem?
Copyright © 2010 Ryan P. Murphy
• Answer!
Copyright © 2010 Ryan P. Murphy
• Answer! Both have value,
Copyright © 2010 Ryan P. Murphy
• Answer! Both have value, but dead trees are
extremely valuable to a forest ecosystem
because they provide habitat such as den
sites, a steady food source of insects, and
ultimately fertilize the soil after decay.

• How did an increase in cover habitat change
the amount of mice captured by the foxes?

Copyright © 2010 Ryan P. Murphy
• Questions to be answered in journal
– What happened to the species less adapted
to eat the seeds over time?
– Answer! The species slowly began to
decrease in population. This occurred
because no two species can occupy the same
niche. They will eventually go extinct.

– Have many (300+ per table group) normal note cards

– Have jumbo note cards (different color represent coyotes)
– Spread 20 rabbits all over large lab table so no two rabbits
are touching but they are all close.
– Toss 5 coyote cards onto large lab table to get the most
rabbits that you can from a short distance.
– If coyote card touches a rabbit then the rabbit is eaten and
removed. The coyote reproduces, pick up cards and double
them. If coyote misses – It dies and is removed. Record
new number after doubling each round
– All the surviving rabbits reproduce as well and then spread
onto the table.
