Morphological features that are simular
1 of 32
What are the 7 levels of classification?
Kingdom
Phylum
Class
Order
Family
Genus
Species
2 of 32
What are scientific names made of?
Genus and Species
3 of 32
Why are scientific names used?
To avoid confusion as common names can be different in different languages
4 of 32
what should start with an upper case letter and which one should start with a lowercase?
(Genus and Species)
Genus should always be capital letter
Species should always be lowercase
5 of 32
What are the five kingdoms of classifaction?
Animals
Fungi
Plants
Bacteria
Single celled organisms
6 of 32
What are the two additional groups that plants can be classified into?
Whether they produce flowers or not
7 of 32
What are the two additional groups that animals can be classified into?
If they are vertebrates or not (backbones)
8 of 32
What are morphological adaptions?
physical features that make it ore likely for an organism to survive in its environment.
9 of 32
What are behavioural adaptions?
Organisms changing their behaviour to increase chance of survival.
10 of 32
Examples of behavioural adaptions?
Hunting as a pack
being nocturnal
dancing to attract a mate
11 of 32
what do animals compete for?
food
mates
territory
12 of 32
what do plants compete for?
Space
nutrients
light
13 of 32
INTRAspecific competition?
competition between individuals of the same species
14 of 32
INTERspecific competition?
competition between individuals of different species
15 of 32
How is animal population size affected?
Pollution
Disease
Number of predators
competition for food and water
16 of 32
How is plant population size affected?
Disease
Pollution
Number of herbivores
Competition for light, water or minerals
17 of 32
What is Biodiversty?
A number of species in an area and how many individuals there are in each species
18 of 32
What are ways to conserve and increase biodiversity?
Sperm Banks
Seed banks
Prevent poaching
educational awareness
captive breeding
legislation of fishing quotas
19 of 32
What is a quadrant used for?
Can be used to estimate how many species there are in a certain area.
20 of 32
How does a line transect work?
A line transect works out the change in distribution of organisms.
It can be used to estimate population size.
21 of 32
Improvement of a line transect?
Take samples at a more frequent intervals
22 of 32
Capture - recapture method?
Go to an area for a set amount of time and capture as many animals than you can see
Mark them and then release them
Go back to the same area at a later date and capture as many animals as you can see. Note how many were recaptured.
23 of 32
What should you consider when doing capture-recapture ?
- Cannot mark an animal in a way that would affects its chance of survival.
-Assume no animals have died
- Assume no animals have immigrated/emigrated
24 of 32
What is an alien species?
A species which has accidentally or deliberately been introduced to an area that they are not naturally found and that causes harm or has a negative impact.
25 of 32
Why is alien species problematic?
Alien species may become invasive and out compete native species, killing off native species.
26 of 32
What are chemical pesticides?
Used to kill pests that may eat crops
27 of 32
What are disadvantages of chemical pesticides?
-Reduce biodiversity
-Expensive as it requires repeated application
-some organisms can become resistant
-pesticides aren't specific and may kill other species
28 of 32
What are advantages of chemical pesticides?
-Readily available
- Easy to use
29 of 32
What is biological control?
Using a living organisms to control the population size of a pest species
30 of 32
Advantages of biological control?
-Specific
-only needs to introduced once
-no chemicals are used
-no resistance
-low cost
31 of 32
disadvantages of biological control?
-initial cost
-could become a pest itself
-could introduce a disease
-takes time to work
