  1. 2. In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche.
  2. 6. an intraspecific relationship in which one species (the commensal) obtains benefits such as food, shelter, or locomotion from another species (the host) without causing adverse effects.
  3. 8. Association between two different organisms wherein one benefits at the expense of the other.
  4. 9. the role an organism plays in a community
  5. 12. an organism that mostly feeds on plants.
  6. 14. a group of species that are commonly found together
  7. 17. a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life
  8. 20. the interaction of individuals that vie for a common resource that is in limited supply,
  9. 25. consists of all the food chains in a single ecosystem
  10. 26. a non-living part of an ecosystem that shapes its environment

  16. 21. organisms that hunt and kill other organisms for food
  17. 22. an area classified according to the species that live in that location
  18. 23. a type of symbiotic relationship where all species involved benefit from their interactions.
  19. 24. an organism that mostly eats meat, or the flesh of animals.
