1 Population Ecology Population Growth

2 Population = ? Group of organisms of the same species living in the same place

3 Population Growth = ? more survive than die

4 What are GOOD conditions for population growth ?
Enough food Enough water Enough space Not too much disease Not too many (efficient) predators No serious natural disasters (examples?)

5 Patterns of Population Growth
Grows quickly at first, then reaches a plateau

6 Exponential, logistic, plateau

7 Carrying Capacity = Maximum number of individuals of one species that a habitat can support

8 Predator curve follows prey curve in time
N1 = prey curve goes up/down first N2 = predator curve goes up/down next

9

10 Fluctuations in Populations

POPULATION DENSITY, DISTRIBUTION & GROWTH.  Density is a measure of how closely packed organisms are in a population  Calculated by … DENSITY # of individuals.

J and S Curves. If things were perfect for a population and all the individuals survived and reproduced at the maximum rate, that growth rate is called.

NOTES Ch 15 #3 2/13 POPULATION STUDIES. When animals first inhabit an area, there are only a few males and females. They have offspring..those grow up.

Aim: How do different types of populations grow? DO NOW 1.Which organism is the predator in this graph? Which is the prey? 2.What happens to the population.

A population is a group of organisms, all of the same species, that live in the same area. Every organism you can think of from spruce.

Limits to Population Growth. No population can grow forever Limit 1 – the 10% rule: Amount of energy at each trophic level is 10% of the level below.
