(10) Biodiversity

Question 1

Define Species

Answer 1

A group of similar organisms that can breed and produce fertile offspring.

Question 2

Define Hierarchy

Answer 2

Taxonomic classification of living organisms in successive levels of complexity.

Small groups within large groups: No overlap between groups

Question 3

Order the Taxonomic groups:
From general to specific

Answer 3

Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

Question 4

Explain Courtship behaviour

Answer 4

Is Species specific:
So members of the same species will be able to perform and respond to that specific behaviour.

Allows members of the same species to recognise each other
Preventing interbreeding.

Can be used to classify species as the more closely related species are, the more similar their courtship behaviour will be.

Question 5

Explain how a phylogenetic system differs from simple hierarchy:

Answer 5

Phylogenetic:
Based on evolutionary history. Shows ancestry points of divergence.

Hierarchy: Based on current shared characteristics

Question 6

Give 3 ways in which courtship behaviour increases probability of successful mating:

Answer 6

1:Forms pair bond

2:Allows organisms to
recognise its own species.

3: Indicates fertility (sexual maturity)
