Answer 7

competition within a species

Question 8

what is INTERspecific competition

Answer 8

competition of different species

Question 9

what is the predator-prey cycle

Answer 9

high number of prey and high number of predator, so predator eats prey. prey is low so less food for predator so predator is low. If predator is low, prey goes up because nothing is eating them. If prey is up then predator has more food, so it goes up also.

Question 10

what is a quadrat

Answer 10

a square frame used to obtain samples of species withing an area

what is a transect

Answer 11

a path on which quadrats are used to obtain samples

Question 12

what is biodiversity

Answer 12

variety and number of different species living within an area

Question 13

equation for estimating biodiversity (quadrats etc)

Answer 13

total number of species in habitat = total number in sample x total area m2 / total sample area m2

Question 14

what is the capture-recapture method

Answer 14

capture animals, then tag and release them
recapture animals after a period of time and record number of tagged or untagged animals

Question 15

equation for estimating population (capture-recapture)

Answer 15

total = original tagged x total recaptured / tagged on recapture

no pollution
only introduced once
if number of pests increase, so does predator
poest-specific

might become pest itself
takes long time

quick
all pests killed
