1. What are some abiotic factors on which your plant depends for its survival? What about biotic factors that affect your plant? Describe some of these factors.
2. How do you know your plants are engaged in competition? For what are your plants competing, and who is the competition?  Brocoli is another good plant so we are competing with them in a way.  
3. How are "winners" and "losers" determined in this struggle? Is it always so clear cut who "wins" and who "loses?" What makes that determination complicated sometimes?  Winners can be plants that are improved a lot and losers can be the plants that don't grow that much.
4. Describe other types of interaction (besides competition) in which your plants are involved. Make sure to explain how this interaction affects each organism involved.
5. What evidence is there in the garden that succesion (or something like it) is occurring in the garden ecosystem? Does it seem more like primary or secondary succession? When the plant is growing and continuing to be healthy
