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 an 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.

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, break down organic matter.

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

= _P_ __ __ __ __ __ __ __ __

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

= _S_ __ __ __ __ __ __ __ __.

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

= _P_ __ __ __ __ __ __ __ __ __

19. An organism’s _H_ __ __ __ __ __ __ or “address” describes area where it lives.

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

= _P_ __ __ __ __ __ __ __ __ __ __ __ __ __

21. _D_ __ __ __ __ __ __ __ __ __ __ __ __ __ __ is the process in which soil bacteria convert nitrates into nitrogen gas which is released into the atmosphere.

22. An organism’s “occupation” or _N_ __ __ __ __ includes all the physical and biological conditions in which it lives.

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

= _C_ __ __ __ __ __ __ __ __

24. “Lunch” for a predator = _P_ __ __ __

25. Each step in food chain or food web is called a _T_ __ __ __ __ __ __ level.

26. Organisms that can make their own food are called _P_ __ __ __ __ __ __ __ __ or AUTOTROPHS.

27. The network of complex interactions formed by linking together all the food chains in an ecosystem = _F_ __ __ __ _W_ __ __.

28. All the organisms that live in a place together with their nonliving or physical environment= _E_ __ __ __ __ __ __ __ __
29. A _L_ __ __ __ __ __ __ __ factor is a requirement that is in short supply or recycles slowly to keep the population in check.

30. The _C_ __ __ __ __ __ __ __ __ __ __ _E_ __ __ __ __ __ __ __ __ Principle
states that no two species can occupy the same niche in the same habitat at the same time.

WHAT SHOULD I KNOW ABOUT BIOSPHERE?


What is ecology?

Be able to define: species; population; community; ecosystem; biome; biosphere;

Tell how these are related.

How is a habitat different from a niche;

What are biotic and abiotic factors?

What is the Competitive Exclusion Principle?

How is the movement of matter and energy through an ecosystem different?

What are autotrophs? Give examples. What are heterotrophs? Give examples.

Compare Photosynthesis and Cellular respiration? What is metabolism?

A food chain? A food web? What do the arrows show? How are these related?

What is an herbivore, carnivore, omnivore, detritivore, decomposer?

How do they get their energy? Be able to give examples of each of these.

What is a trophic level? What percentage of energy is passed on from one trophic level to the next?

Be able to identify: autotrophs (producers) and heterotrophs (consumers) in a food web and tell what effect changes in a population will have on other populations.

What is an Ecological Pyramid? What are the 2 types?

Be able to answer ?’s about the 4 cycles you learned about.

(water, carbon, nitrogen, phosphorus)

How do these atoms enter and leave the atmosphere, land, water, and cycle through the ecosystem?

In which cycle does the atmosphere NOT play a role?

Which biomolecules are important to living things and which cycles provide the atoms to build these?

What is transpiration? Nitrogen fixation? Denitrification? Evaporation? Condensation? Precipitation?

Which organisms play a role in these processes?

What are the ways organisms interact in an ecosystem? (Competition, Predation, Symbiosis)

What are some things organisms must compete for?

What is a limiting factor? How does it affect a population? What are the two types?

What is primary productivity? An algal bloom?

What happens when an over abundance of a limiting factor becomes available?
What is predation? What is a predator? Prey?

What are the 3 kinds of symbiosis? Be able to identify examples of each?

What is succession? What are the two types? What is a pioneer species? Be able to give examples.

What is a climax community? Carrying Capacity?
