|
|
|
How does a niche differ from a habitat?
|
A niche is it's job and a habitat is the enviroment around it.
|
|
|

|
Transpiration
|
|
|
What is meant by interconnectedness or interdependence?

All organisms are affected by the living and nonliving organisms.
|
|
|
What is ecology?
|
The study of reactions between organisms, living and non living components of the enviroment.
|
|
|
What is biodiversity?
|
The genetic # and variety of organisms in a given area during a specific period of time.
|
|
|
What are different ways a habitat can be altered?
|
By addding or taking away resources.
|
|
|
What are the four factors that can change a population size?
|
Birht Rate, Death Rate, Immigration and emmigration.
|
|
|
What are producers, consumers and decomposers?
|
Producers are autotrophs that capture sun energy to make organic molecules. Consumers eat other organisms to get their energy. Decomposers break down dead organisms to make nutrients.
|
|
|
What are biotic and abiotic factors?
|
Biotic factors are the living components of the enironment. Ex:Plants
Abiotic factors are the nonliving components of the environment. Ex:Oxygen & Humidity |
|
|
What is the difference between a food chain and a food web?
|
food chain is a single pathway.
Food webs show the interconnectedness between organisms. |

|
|
How does a niche differ from a habitat?
|

|
|
|
Explain why the same area can support a greater # of herbivores than carnivores.
|
Because there has to be more energy to go up
|
|
|
Why is the aamount of sunlight important to the animals in an ecosystem?
|
The sunlight is where the energy is.,
|
|
|
What is acclimation? How does it differ from evolution?
|
Acclimation is an organisms adjustment to an abiotic factor. Evolution is how a species evolves or changes over a long period of time
