The living factors in an ecosystem
Biotic factors
100
The non-living factors in an ecosystem
Abiotic factors
100
This growth shows a j-shaped curve
exponential growth
100
When competition occurs, rate of population growth slows and either levels off or stops, resulting in an "s" shaped curve.
logistic growth
200
This level will have the largest amount of biomass (biological organisms) on an energy pyramid
Producers
200
types of factors that limit how large a population can grow.
Limiting factors
200
Maximum number of organisms that can be supported in a given environment.
Carrying Capacity
200
Draw a graph, then circle the carrying capacity of the graph.
300
What type of species has a large number of offspring, low parental care, short life span, and reaches maturity faster
R selected
300
What kind of growth curve would there be within a population if there are few individuals with an a lot of resources?
Exponential growth
300
This biotic factor could affect the size of a population
A. amount of available water
B. range of temperatures
C. Number and type of predators
D. Concentration of soil nutrients
C - Number and type of predators
300
Provide an example of an R selected species and a K selected species
R - oysters, salmon, trees, mosquitoes, bunnies
K - humans, whales, lions, gorillas, bears
400
Match the letter to the type of survivorship curve
A - Type 1
B - Type 2
C - Type 3
400
This type of growth curve could be expected from a population of rabbits that has reached its carrying capacity.
What is logistic growth
400
What term goes with this definition: the number of individuals living in a defined area at a given time or # of individuals/ area?
Population density
400
Write the term to the correct definition
1. Death rate
2. Predicted length of survival
3. Ability to reproduce
4. Birth of new individuals
5. Number of offspring
1. Death rate - MORTALITY
2. Predicted length of survival - LIFE EXPECTANCYY
3. Ability to reproduce - FECUNDITY
4. Birth of new individuals - NATALITY
5. Number of offspring - FERTILITY
500

6. Type 3 curve
1. R
2. K
3. K
4. R
5. K
6. R
