Bio 10 - Biodiversity

Question 1

What do members of a species all have in common?

Answer 1

They are capable of breeding to produce living, fertile offspring

Question 2

What is a species?

Answer 2

A group of organisms that are similar to each other bur different from members of other species

Question 3

What is classification?

Answer 3

The Grouping of species

Question 4

What is taxonomy?

Answer 4

The practice of biological classification

Question 5

What are the two type of classification?

Answer 5

• Artificial Classification

- Natural classification

Question 6

What is artificial classification?

Answer 6

Divides organisms by physical characteristics

Question 7

What is natural classification?

Answer 7

Based upon the evolutionary relationships. Arranges groups into a hierarchy

Question 8

What is the problem with artificial classification?

Answer 8

Eg. Just because animals have the same number of legs doesn’t mean they are the same

Question 9

What is the largest taxonomy group?

Answer 9

Domain

Question 10

List the taxonomy groups in order.

Answer 10

Domain, Kingdom, Phylum, Classes, Orders, Families, Genera and Species.

Question 11

What is Phylogeny?

Answer 11

The evolutionary relationship between organisms. It reflects the evolutionary tree that led to the organism.

Question 12

What is species diversity?

Answer 12

The number of different species and the number of individuals of each species within one community

Question 13

What is genetic diversity?

Answer 13

The variety of genes possessed by individuals that make up any one species

Question 14

What is ecosystem diversity?

Answer 14

The range of different habitats within a particular area.

Question 15

What are the two components of species diversity?

Answer 15

• Number of different species in given area

- The proportion of the community that is made up of an individual species

Question 16

How do humans reduce species diversity control agricultural ecosystems

Answer 16

• Farmers select crops that are more productive so the frequency of alleles are reduced
• Crops sprayed with pesticide and manmade fertiliser

Question 17

What’s the impact of deforestation?

Answer 17

• Forests contain many varied and different habitats high in species diversity.
• Permanent clearing of the forest leads to lots of habitats and in turn loss of biodiversity

Question 18

What does courtship behaviour enable animals to do?

Answer 18

• Recognise members of their own species
• identify a mate that is capable of breeding
• form a pair bond
• synchronise mating
• become able to breed
