HONORS BIOLOGY BIOSPHERE STARTS WITH ?

1. The _B ______is made up of the parts of the planet including land, water or atmosphere in which all life exists.

2. _N______F______is the process in which nitrogen gas from the atmosphere is converted into ammonia by bacteria that live in the soil and on the roots of plants called legumes

3. The type of symbiosis in which both organisms benefit from living in close association is called _M______.

4. Unlike carbon, hydrogen, and oxygen, _P______, an element found in DNA, does NOT enter the atmosphere as it cycles through the ecosystem.

5. A _P______is a group of individuals that belong to the same species and live in the same area.
6. _T______,the process in which water evaporates from the surface of green plant leaves, is one way water molecules return to the atmosphere.

7. A group of organisms so similar to one another that they can breed and produce fertile offspring = _S______
8. An _O______eats both plants and animals.

9. A symbiotic relationship in which one member of the association benefits while the other is neither helped nor harmed = _C______.

10. An _H______obtains energy by eating only plants.

11. Type of interaction in which organisms fight to use a resource in the same place and at the same time = _C______.

12. Another name for a CONSUMER = _H______.

13. An organism that eats only meat is called a _C______.

14. _E______is the science that studies the interactions of organisms with each other and with their environment.

15. Bacteria and _F______are decomposers, an important group of heterotrophs that break down organic matter and return nutrients to ecosystems.

16. Some bacteria use _C______, a process in which energy from the chemical bonds of inorganic molecules is used to produce carbohydrates in the absence of light.

17. An interaction in which one organism captures and feeds on another

= _P______

18. Atoms like carbon, nitrogen, and phosphorus are reused and passed throughout parts of the biosphere in _B______C______.

19. An interaction in which one organism lives in a close association with another

= _S______.

20. A _P______captures and eats a prey animal.

21. Type of symbiosis in which one organism benefits while the other is harmed.

= _P______

22. An organism’s _H______or “address” describes the area where it lives.

23. Process in which energy from sunlight is used by green plants to convert carbon dioxide and water into oxygen and carbohydrates = _P______

24._D______is the process in which soil bacteria convert nitrates into nitrogen gas which is released into the atmosphere.

25. An organism’s “occupation” or _N______includes it’s physical location plus all of it’s
biological interactions in that place.

26. All the different populations that live together in a certain area form a

= _C______

27. “Lunch” for a predator = _P______

28. Quaternary consumers eat _T______consumers.

29. Organisms that can make their own food are called _P______or
A ______.

30. The network of complex interactions formed by linking together all the food chains in an ecosystem = _F______W_ __ __.

31. All the organisms that live in a place together with their nonliving or physical environment

= _E______
32. _A______factors are all the non-living factors that shape ecosystems such
as climate, precipitation, wind, nutrient availability, soil type, and sunlight.
33. A _L______factor is a requirement that is in short supply or recycles slowly to keep the population in check.

34. The _C______E______Principle
states that no two species can occupy the same niche in the same habitat at the same time.

35. Every food chain has a _P______at the beginning.

36. Primary consumers are eaten by _S______consumers.

37. Each step in food chain or food web is called a _T______level.

38. Type of interaction in which organisms live together in a group for protection and share
food, grooming and child-care responsibilities = _C______.

39. Plants (like soybeans, clover, and alfalfa) that live in symbiotic relationships with nitrogen
fixing bacteria are called _L______.

40. Heterotrophs get the _N______they need to build proteins and nucleic
acids from eating _F______not by breathing.

41. CARBON is an important atom found in all the major biomolecules including
_C______, _P______,
_L______, and _N______A______(like DNA & RNA).

42. The maximum population size that a habitat can support without destroying the
ecosystem is called the _C______C______,
and thisis determined by the limiting factors in an ecosystem.
