Across
  1. 4. Adenosine triphosphate
  2. 6. relating to biology or living organisms.
  3. 7. the action of reproduction
  4. 8. thing that gives us light
  5. 9. all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds.
  6. 15. cutting down the forests
  7. 18. a green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.
  8. 19. each of a number of small areas of habitat, typically of one square metre, selected at random to act as samples for assessing the local distribution of plants or animals.
  9. 22. a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus and denoted by a Latin binomial
  10. 23. the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

  18. 37. the state or process of rotting; decay.
  19. 39. the regions of the surface and atmosphere of the earth or another planet occupied by living organisms.
  20. 42. the action of breathing.
  21. 43. everything is made up of it
