1. In a case of secondary succession, three species of wild grass invaded a field the 1st growing season after the farmer abandoned the field. By the 2nd season, one of the wild grasses dominated the field. A possible factor in the succession was:
equilibrium, facilitation, immigration, or mutualism?
I think it’s facilitation but I’m not positive

2. Which is least likely to kill the organism it feeds on: parasitoid, predator, seed eater, carnivore, parasite
I think it’s a parasite but again, I’m not sure

3. Which of the following is a term that ecologists do not use to describe communities: species richness, species diversity, symbiosis, or stability
