What word describes the environment in which a particular organism lives? 2

Habitat 3

4 All of the factors that a species needs to survive, stay healthy, and reproduce.

5 Niche

6 Species that occupy similar niches but live in different geographical regions

7 Ecological Equivalents

8 What term refers to the concept that two species can not occupy the exact same niche?

9 Competitive Exclusion

10 What are the three possible outcomes of competitive exclusion?

11 –One species is better suited to the niche and the other will either be pushed out or become extinct. –The niche will be divided. –The two species will further diverge.

12 ___________ occurs when two organisms fight for the same limited resource

13 Competition

14 ___________ occurs when one organism kills and eats another organism

15 Predation

16 What are the three types of symbiosis (Give and example of each type)

17 Parasitism Mutualism Commensalism

What is the difference between Interspecific and Intraspecific Competition? 18

19 Interspecific – competition between separate species Intraspecific – competition between members of the same species

What are the two classes of parasites? Provide an example of each type. 20

21 Endoparasites – (hookworms & tapeworms) Ectoparasites - leeches

22 What is the formula for calculating population density?

23

24 What is the difference between population density and population dispersion?

25 Density – number of individuals in a defined space Dispersion – how those individuals are spread out in that defined space

26 What three types of population dispersion patterns are found in nature?

27 Clumped, Uniform, & Random

28 Describe a Type 1 survivorship curve.

29 Most babies live and the population does not begin to die off until most individuals have reached close to maximum life span

30 What types of organisms display type 1, type 2, and type 3 survivorship curves?

31 Type 1 – humans & large mammals Type 2 – birds & reptiles Type 3 – invertebrates & plants

32 The maximum number of individuals in a population that the environment can support.

33 Carrying Capacity

34 What term refers to the one thing that has the largest influence on the maximum number of individuals that can live in a given area

35 Limiting Factor

36 A dramatic decline in the size of a population over a short period of time.

37 Population Crash

38 Name 3 density-dependent limiting factors and 3 density independent limiting factors

39 Density Dependent – competition, predation, & disease Density Independent – unusual weather, natural disasters, & human activities

40 Differentiate between exponential and logistic growth. Draw a graph representing each growth curve and explain what is happening on each graph

41

42 What four factors affect the size of a population?

37 Births, deaths, immigration, & emigration

44 The sequence of biotic changes that regenerate a damaged community or create a community in a previously uninhabited area.

45 Succession

46 The first organisms that live in a previously uninhabited area

47 Pioneer Species

48 What type of succession is pictured below?

49 Secondary Succession

50 Explain the difference between primary and secondary succession.

51 Primary – the establishment and development of an ecosystem in an area that was previously uninhabited Secondary – the reestablishment of a damaged ecosystem in an area where the soil was left intact

52 Label each of the marked organisms in the following food web Producer/Primary Consumer/Secondary Consumer Herbivore/Carnivore/Omnivore/Autotroph Specialist/Generalist
