V and J

6.
Which of the following would be considered density independent factors?
a)
Land size
b)
Resource depletion
c)
Volcanoes
d)
Competition for food
7.
Which of the following would be considered density dependent factors?
a)
Hurricanes
b)
Volcanoes
c)
Flood
d)
Competition for food
8.
Is there a relationship between the predator and prey populations?
a)
No. As the prey population increases, the predator population decreases and remains low.
b)
No. As the prey population increases, there is more food for the predators and they increase in numbers until the food runs out and then the population starts to die off.
c)
Yes. As the prey population increases, there is more food for the predators and they increase in numbers until the food runs out and then the predator population starts to die off.
d)
Yes. As the prey population increases, the predator population increases and remains high.
9.

a)
Which organism is the prey and which is the predator
b)
Which organism is eating which organism
c)
The flow of energy
d)
The different trophic levels
10.
Which of the following are abiotic factors?
a)
Predators
b)
Weather
c)
Other animals

None of the above
11.

a)
1,000 Joules
b)
100 Joules
c)
10 Joules
d)
1 Joule
12.
In a food chain, the primary producer has 1,000 Joules of energy. How much energy does the secondary consumer receive?
a)
1,000 Joules
b)
100 Joules
c)
10 Joules
d)
1 Joule
13.

10 Joules
d)
1 Joule
14.

a)
.1%
b)

a)
Energy is lost to the atmosphere
b)
Energy is lost during digestion
c)
Decomposers take the rest
d)
It takes energy to stay alive
17.
What is a limiting factor?
a)
Anything biotic that limits a population
b)
Anything that limits the size of a population
c)
Anything abiotic that limits a population
d)

a)
climax community
b)
primary succession
c)
secondary succession
19.
There are two types of population graphs, a J shape and an S shaped graph. Will the J shaped graph ever reach carrying capacity?
a)
No, because the organisms can start to consume each other to survive
b)
Yes, because eventually the population will run out of resources
c)
No, because the organisms can move to another area where there are more resources
d)
Yes, because predators will keep the population small
20.
Which one is the correct definition of carrying capacity?
a)
Carrying capacity is the number of organisms in a population that can be supported by the environment
b)
Carrying capacity is the number of organisms in a population that can be supported by the predators
c)
Carrying capacity is the number of species in a population that can be supported by the environment
d)
Carrying capacity is the number of organisms at it's peak in an environment
21.
What is intraspecific competition?
a)
When individuals of the same species compete for the same resource
b)
When individuals of different species compete for the same resource
22.
