Classroom Rules Dress properly -no hats, guys-pants must be pulled up, girls- lets not expose ourselves. No eating or drinking after 1st period breakfast (complete by 7:25) Come to order when I have clapped my hands. Respect each other and the teacher Use proper language. No sign language No hitting/pushing/shoving
5
objectives Compare and contrast factors that influence the growth rate of a population. Determine the carrying capacity of an area. Model how the age structure and other characteristics of a population can vary from one country or ecosystem to another.
6
Essential Question What factors influence the carrying capacity of populations? How do populations differ based on variations in their characteristics?
7
Vocabulary Survivorship curve immigration emigration migration
carrying capacity density-dependent factor density-independent factor population density population distribution age structure diagram
8
What are the limiting factors that determine an ecosystem’s carrying capacity?
Water space food disease predators
9
Do Now: on your paper Notes are in blue.
Aim: How do limiting factors determine an ecosystem’s carrying capacity? Do Now: on your paper Notes are in blue.
10
Population growth is based on available resources.
Exponential growth is a rapid population increase due to an abundance of resources.
11
Logistic growth is due to a population facing limited resources.
12
Carrying Capacity The amount of organisms the environment can support without competition When organisms exceed carrying capacity, competition begins
13
What happens when carrying capacity is exceeded?
1. A population may even out at its carrying capacity Chaotic pattern Cyclical pattern Damped oscillation pattern 2. A population may crash- a population crash is a dramatic decline in the size of a population over a short period of time.
14
What happens when carrying capacity is exceeded?
15
Limiting factors limit population growth.
A limiting factor is something that keeps the size of a population down.
16
Limiting Factors May be Density Dependent or Density Independent
Density-Dependant Density-Independant Not affected by the population density These can affect the population SIZE at any time. Affected by the population density These will not affect the population SIZE until it grows too high State whether the following factors are density DEPENDENT or INDEPENDENT Predation Natural disasters Disease Overcrowding Competition Temperature Parasitism Sunlight Human activities
17
Can carrying capacity change over time?
Limiting factors can alter the carrying capacity The orange aliens each need a lychee and a quib to survive. What is the carrying capacity? What is the limiting factor?
18
Can carrying capacity change over time?
A drought results in fewer lychees. What is the new carrying capacity? What is the new limiting factor?
19
Wrap Up! Turn to the chapter 4 word wall on page 193.
Record at least two “new to you” words that we used in class today.
