Across
  1. 3. An interaction between individuals of different species.
  2. 6. An interspecific relationship in which one species benefits and the other is neither helped nor harmed (+/0).
  3. 10. All the populations of different species living and interacting in a defined area.
  4. 12. Conspicuous warning colouration or signals that advertise toxicity, danger or unpalatability to predators.
  5. 15. A structure, signal or behaviour that reduces the probability of being detected, captured or eaten.
  6. 16. An organism hunted and consumed by a predator.
  7. 19. A photosynthetic parasite that obtains water and mineral nutrients, but not all of its organic food, from a host.
  8. 20. An interaction in which chemicals produced by one organism inhibit or kill another organism.
  9. 21. An organism that captures, kills and consumes another organism.

  1. 1. A form of exploitation in which a parasite benefits by living in or on a host, which is harmed (+/-).
  2. 2. An interspecific relationship in which both species benefit (+/+).
  3. 4. An interaction in which organisms use the same limited resource, reducing the fitness of both (-/-). It may be interspecific or intraspecific.
  4. 5. A form of exploitation in which an animal consumes plant or algal tissue.
  5. 7. The release of biochemicals by one plant that inhibit the germination, growth or survival of another plant.
  6. 8. A plant that grows on another plant for physical support without taking nutrients from it; the host is generally unaffected.
  7. 9. Colour, pattern, shape or behaviour that makes an organism difficult to detect against its background.
  8. 11. A type of mimicry where two or more harmful or unpalatable species share a similar warning signal, reinforcing predator learning.
  9. 13. An interspecific relationship in which one species benefits and the other is harmed (+/-), including herbivory, predation and parasitism.
  10. 14. An organism that lays its eggs in another individual's nest so the host provides care for the parasite's offspring.
  11. 17. A form of exploitation in which a predator captures, kills and consumes prey.
  12. 18. A type of mimicry where a palatable or harmless species resembles an unpalatable or harmful model, reducing its risk of predation.
