Question 1

What is biodiversity?

Answer 1

It refers to the variety of living organisms within an area

Question 2

What are the three different types of biodiversity

Answer 2

Habitat species and genetic

Question 3

Explain habitat diversity

Answer 3

Number of different habitats within an area

Question 4

Create a habitat diversity leads to

Answer 4

Great species by diversity

Question 5

Give some examples of habitat bio diversity

Answer 5

Sand dunes, Woodlands Meadows and streams

Question 6

What is species biodiversity?

Answer 6

It is the variety of species living within an area

Question 7

How is species diversity broken down into?

Answer 7

Species evenness and species richness

Question 8

Explains species richness

Answer 8

Number of different species living in a particular area

Question 9

Explain species even less

Answer 9

Comparison of the number of individuals of each species living in a community

Question 10

Explain genetic diversity

Answer 10

The variety of jeans which make up a species

Question 11

What are the two methods of sampling?

Answer 11

Random sampling and non-random sampling

Question 12

What is random sampling?

Answer 12

Selecting individuals by chance it can be done by our computer or just random tables

Question 13

Explain non-random sampling

Answer 13

It is not random and it is broken down into three techniques opportunistic stratified and systematic

Question 14

Explain opportunistic sampling

Answer 14

Uses organisms which are available

Question 15

Explains stratified sampling

Answer 15

Populations are divided into a number of strata which is based on a particular characteristic and then a random sample taken from each of these strata proportional to its size

Question 16

Explains systematic sampling

Answer 16

Areas within an overall habitat is identified. They are then samples separately using a line transact of belt transact

Question 17

What are the 4 ways of sampling animals?

Answer 17

Pooter
Sweet nets
Pitfall traps

Question 18

Explain how to use a pooter

Answer 18

You suck on a mouthpiece with where insects are drawn into the holding chamber by the inlet tube it is used to catch small insects

Question 19

Explain how to use sweeping nets

Answer 19

You catch insects in areas of long grass

Question 20

Explain how to use a pit full trap

Answer 20

You catch more insects like spiders and slugs are hole is dug in the ground where insects fall into

Question 21

How do you sample. Plants and what are the two types?

Answer 21

Quadrats
Point quadrat and frame quadrat

Question 22

Explain point quadrat

Answer 22

A frame has a horizontal bar which intervals along the bar long pins are pushed through the bar which reached the ground. Each species of the plant in the pin touches is

Question 23

Frame quadrat

Answer 23

Square frame is divided into a grade of equal section type a number of species within each section of record

Question 24

Frame quadrat is used to sample the population of plants living in a habitat and it’s done by

Answer 24

Density
Frequency
Percentage cover

Question 25

How do you calculate bod diversity?

Answer 25

Using the Simpsons index of diversity

Question 26

What are factors which affect genetic pay diversity?

Answer 26

Mutations which can create a new allele Interbreeding Selective reading Natural selection

Question 27

What is the formula for the proportion of polymorphic gene loci

Answer 27

Number of polymorphic gene Lokai divided by the total number of Loki

Question 28

If the polymorphic gene locate is greater than the genetic diversity is

Answer 28

Greater

Question 29

What are the three main factors which affect by a diversity?

Answer 29

Human population growth Agriculture And climate change Also deforestation

Question 30

What are the reasons for maintaining bod diversity?

Answer 30

Aesthetic Economic and ecological

Question 31

What are the aesthetic reasons?

Answer 31

To protect landscapes

Question 32

Economic reasons

Answer 32

To reduce soil depletion

Question 33

What are the ecological reasons?

Answer 33

To protect the keystone species and maintain genetic resource

Question 34

What are the two main categories? Scientist tried to maintain bod diversity conservation?

Answer 34

in situ conservation Ex situ conservation

Question 35

What is in situ conservation?

Answer 35

It takes place within an organisms natural habitat it maintains a genetic diversity and maintains evolutionary adaptations which enable a species to adapt continuously to changing environmental conditions Examples include wildlife reserves and marine conservation sounds

Question 36

What is ex situ conservation?

Answer 36

Removal of organisms from their natural habitat Examples include botanic gardens seed banks in captive breeding programs

Question 37

What is CITES agreement?

Answer 37

Agreement between countries to regulate the trade in threaten species agreement makes it illegal to kill or trade endangered species

Question 38

What is the CBD agreement? Also known as the Rio convention on biological diversity

Answer 38

Is the international pact to share responsibility for conserving biodiversity? It aims to develop strategies and guidance to government to use the resources sustainable

Question 39

What is the county stewardship scheme? Also also known as CSS?

Answer 39

Protect wild areas and it pays landowners to implement techniques such as growing hedge grows to increase by diversity
