Biodiversity

Question 1

Why is sampling good

Answer 1

Easier than counting every single organism

Question 2

Higher Simpsons index

Answer 2

High species diversity so resilient to change

Question 3

Sampling when estimating abundance or distribution of a species in field

Answer 3

Set up grid at right angles of each other. Use random coordinates

Question 4

Controlling net movement

Answer 4

Speed width and amount of sweeps so more is caught

Question 5

One example of conversion

Answer 5

Repairing fences

Question 6

In situ

Answer 6

In their habitat

Question 7

Decline in one species population effect on everyone

Answer 7

Decline in predators or prey increase is other species more competition etc

Question 8

Why can a predator improve long term survival of a species

Answer 8

Selection pressure. Weaker individual with less beneficial alleles are removed

Question 9

Why the evolution of antibiotic resistance jas implications for human populations

Answer 9

Bacterial diseases are harder to treat. So it increases deaths

Question 10

How does antibiotic resistance in bacteria provide evidence for theory of evolution

Answer 10

Antibiotic is selection pressure. Evolution is observable

Question 11

A high proportion of heterozygous gene loci means

Answer 11

High genetic diversity so high genetic variation so less vulnerable

Question 12

Variables to control when conducting an experiment to do with belt transect

Answer 12

Age of plants, time or weather of day, gradient of the ground

Question 13

That word you wanna use instead of decrease extinct

Answer 13

Disappear

Question 14

Is a transect line random

Answer 14

No

Question 15

How to improve kick sampling

Answer 15

Kick same number of times

Question 16

Why use a frame quadrant instead of a point

Answer 16

You’re less likely to miss any species

Question 17

Answer 17

Question 18

How is agriculture bad for biodiversity

Answer 18

Monoculture - explain
Bio accumulation - explain
