Question 22

Climate change

Answer 22

A change in global or regional climate patterns

Question 23

Fluctuations

Answer 23

A irregular rising and falling in number or amount

Question 24

R breeding strategy

Answer 24

R selection species are those that emphasise high growth rates, typically exploit less crodwd ecological niches and produces many offspring esch of which has a relatively low probability of surviving to adulthood (lots) (honey bee, coconut crabs)

Question 25

K breeding strategy

Answer 25

K selection species possess relatively stable populations and tend to produce relatively low numbers of offsprimg however indivudual offspring tend to be quite large in comparison with r selected species (less) (chimpanzee)

Question 26

Immigration

Answer 26

Move into a non native country or region to live

Question 27

Emmigration

Answer 27

Leave one locatioj such as ones native country or region to live in another

Question 28

Divergent evolution

Answer 28

Two different species do not share a common ancestor but have developed siikar characteristics
(Shark and dolphin body)

Question 29

Divergent evolution

Answer 29

Two different species share a common ancestor but have developed different characteristics
(Darwin finches)

Question 30

Parallel evolution

Answer 30

Developent of related species from a common ancestor, species evolve at the same rate over time due to similar environmental pressures

Question 31

Primary consumer

Answer 31

Animal that eats the primary product

Sheep and grass

Question 32

Secondary consumer

Answer 32

Animal that eats a primary animal

Question 33

Natural selection

Answer 33

The process through which populations of living organisms adapt and change, desirable characteristics are passed onto offsprimg
