  1. 4. the chemical inhibition of one plant by another, due to the release into the environment of substances acting as germination or growth inhibitors.
  2. 5. a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium.
  3. 7. a form of competition in which individuals of different species compete for the same resources in an ecosystem.
  4. 8. a phylum under kingdom Animalia containing over 11,000 species of aquatic animals found both in freshwater and marine environments.
  5. 10. the series of changes in the life of an organism including reproduction.
  6. 11. a multicellular organism whose mouth develops from a primary embryonic opening.
  7. 14. organisms that have a coelom.
  8. 16. an interaction in population ecology, whereby members of the same species compete for limited resources.
  9. 17. a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into a diploid.
  10. 18. each of a number of small areas of habitat, typically of one square meter, selected at random to act as samples for assessing the local distribution of plants or animals.
  11. 19. an animal that does not possess a body cavity.

  1. 1. a process in which saprobionts feed by secreting enzymes through the cell membrane onto the food.
  2. 2. an organism with body cavity that is not derived from the mesoderm, as in a true coelom, or body cavity.
  3. 3. the vegetative part of a fungus, consisting of a network of fine white filaments.
  4. 6. a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.
  5. 9. involves collecting and analyzing numerical data for statistical analysis.
  6. 12. a path along which one counts and records occurrences of the objects of study.
  7. 13. usually perforated by pores large enough for ribosomes , mitochondria, and sometimes nuclei to flow between cells.
  8. 15. data that can be counted or measured, and given a numerical value.
