Biodiversity and Flow of Energy

Question 1

-Ultimate source of energy

Answer 1

Sun

Question 2

• Transferred and transformed from one organism to another
• 2 Organism feed on another
• Decomposers extract this from remains
• Inorganic materials are cycled, this is not

Answer 2

Energy

Question 3

• Many different species

- Broad distribution of genetic diversity

Answer 3

High biodiversity

Question 4

• Only a few species

- Low genetic diversity within population

Answer 4

Low biodiversity

Question 5

-Refers to the diversity of habitats in a given area

Answer 5

Habitat diversity

Question 6

refers to the total number of relative abundance of species

Answer 6

Species diversity

Question 7

• Refers to the total number of genetic characteristics of a specific species, subspecies, or a group of species
• enables population to adapt to changing environments (survival of the fittest)

Answer 7

Genetic Diversity

Question 8

This helps makes an ecosystem more stable.

Answer 8

Biodiversity

Question 9

-The study of the factors that influence the size, density, distribution and growth of a population

Answer 9

Population energy

Question 10

Refers to a group of organisms of the same species that live in a particular area

Answer 10

Population

Question 11

Any environmental factor that limits the size of a population

Answer 11

Limiting factor

Question 12

Properties of population

Answer 12

Population density, ecological density and population distribution

Question 13

Refers to the number of individuals per unit area or unit volume

Answer 13

Population density

Question 14

Refers to the number of individuals per unit area of available space

Answer 14

Ecological density

Question 15

Is the spatial distribution of individuals of a population

Answer 15

Population distribution

Question 16

-Individuals in a population are independent of each other because the habitant conditions are relatively uniform

Answer 16

Random dispersion

Question 17

-Individuals are about the same distance from one another due to competition

Answer 17

Regular/Uniform dispersion

Question 18

-Individuals clump together because resources and suitable habitats

Answer 18

Clumped/Aggregated dispersion

Question 19

Factors that influence population size

Answer 19

Birth rate, Date rate, immigration, emigration

Question 20

• Assumes a constant growth rate
• J-shaped population
• In order to have this, resources must be unlimited

Answer 20

Exponential Growth

Question 21

• More realistic model where growth varies with population size
• S-shaped
• Tend slow down growth once capacity is reached

Answer 21

Logistic Growth

Question 22

• Affect a population when it reaches a certain density
• Includes: competition, predation, diseases, parastism, crowding and stress (man made problems or problems within control)

Answer 22

Density dependent factors

Question 23

• Affect a population regardless of density

- Includes: food, nutrient limitation, pollutants, weather disturbances, natural disasters (problems out of control)

Answer 23

Density independent factors
