Energy Flow
What are the main parts of a simple food chain?
What is a Producer, Primary Consumer, Secondary Consumer, and Decomposer
What is a primary consumer?
An organism that gets its energy straight from the producer
True or False: A food web could have different, interlocking food chains
True
If scientists want to find out how many organisms there are in the whole area, only using the organisms in a small part of the area, what method should they use?
Sampling
How many types of factors are there in an environment.
2
Which is more complex? Food Web or Food Chain
Food Web
What is a secondary consumer?
An organism that gets its energy from a producer but they get it through eating the primary consumer
What does a food web show?
energy transfer
If a scientists sees that all the beetle in an area are green what kind of observation is that?
Direct observation
If something is alive in the community, what is that factor called?
Biotic
How much energy is transferred through each level of the energy pyramid? (What %)?
10%
In a simple food chain, how many types of consumers are there usually?
What is the difference between a food web and a food chain?
a food web is more complex and can have multiple food chains inside a the food web
If a scientists see that he caught 30 green beetles and 10 blue beetles, he assumes that there are more green then blue beetles. What kind of observation is that?
Indirect Observation
What is something non-living in the environment called?
what is the main way energy is lost between levels?
Heat
Is it possible to have more than one primary or secondary consumer?
Yes (usually in a food web)
True or False: only carnivores can be in a food chain or web
False
When a scientist makes and indirect observation, are the observations always going to be correct?
No
What is it called when all the living factors are living together?
Community
What do the arrows show in a food web?
What is a consumer that gets its energy from a secondary consumer called?
Tertiary consumer
Which shows a more simple picture of energy flow? A food chain, or a food web?
Food chain
True or False: Making a direct observation is better than making an indirect observation
False (A direct observation might not always be possible. A direct observation is just usually more accurate)
What is it called when all the biotic and abiotic factors are living together?
An ecosystem
