1)_____________________is the study of how organisms interact with their environment.
It begins with a group of organisms of the same 2)_______________ which are capable of
interbreeding and producing fertile offspring.
When the living populations of organisms interact with their nonliving or physical environment
they make up an 3)________________________.
If a group of ecosystems have the same climate and dominant plant communities they are a
4)_______________________, such as grassland, tropical forest, deciduous forest, or desert. All
biomes on Earth combine to form the biosphere, the highest level of organization studied in
biology.
Energy must be captured by the sun during the process of 5)________________________, which
converts sunlight energy into chemical energy in glucose.
Green organisms that do this are 6)_______________________ (self-feeders). Since they
produce food for the entire ecosystem these organisms are also called 7)__________________.
The organisms in the ecosystem that cannot produce their own food are called
8)____________________(other-feeders).
They are classified by what other organisms they eat. Ones that eat producers are
9)_________________.
Based on their place in the food chain, they are also known as 10)______________________.
These plant eaters can then be eaten by 11)____________________, which in a food chain
represent the level called 12)_____________________.
The carnivores at the top of the food chain are known as 13)___________ ________________.
14)___________________ , such as mites and earthworms feed on plant and animal remains.
Finally, heterotrophs known as 15)______________ _______ break down all these organisms
when they die and return their materials to the environment.
The sun's energy moves through these 16)_____________ (feeding) levels in single pathways
known as 17)_________________.
In the real world, single isolated pathways do not exist alone. Reality is that energy can flow
through a great variety of pathways known as a 18)____________ ______________.
As energy moves through a food chain or food web, only 10% makes it to the next trophic level.
The 100% of energy found in producers will result in only 10% found in herbivores. By the time
you get to top carnivores there is only .1% left
In an ecosystem, biological influences on organisms are known as 19)___________________.
Whereas nonliving factors such as air, sunlight, and land are known as
20)___________________.
The total number of organisms that an ecosystem is capable of supporting is its
21)____________________.
When organisms live together in ecosystems, they interact. 22)____________________ occurs
when organisms attempt to use a 23)_________________, or a life necessity, in the same place,
at the same time.
24)_____________________is when one organism captures and feeds on another.
A relationship in which two organisms live closely together is 25)_______________.
One form of symbiosis is 26)____________________________ in which both organisms benefit
from the relationship.
In 27)__________________________ one organism benefits while the other doesn’t care.
Finally, the type of interaction in which one organism is helped in the relationship, while the other
organism is hurt is 28)__________________.
29) ________________a system formed by the interaction of a community of organisms with
their physical environment
30) A ________________ is a group of organisms of the same species living together in an area
31) ______________ is when an organism will eat both plants and animals.
32) A ______________ is the particular role an organism plays in the environment.
