13
Although three different bird species all inhabit
the same type of tree in an area, competition
between the birds rarely occurs. The most likely
explanation for this lack of competition is that
these birds

  • (2.) saprophytism
  • (3.) commensalism
  • (4.) parasitism

16
Several years after a building had been torn down

  • (2.) land use management 
  • (3.) ecological succession
  • (4.) biological control

17
  • algae? minnow ? lake trout ? hawk
  • Which organism has the greatest energy?
  • 2. Describe one effect that an increase in the
    minnow population would have on the ecosystem.
  • 3. Why are the algae an important part of this
    food web
  • 4. What do the arrows represent?

algae
A decrease in algae
An increase in lake trout
They are producers.
The flow of energy through the food chain.
18

    of available energy?
