B2.7-Clasification & Biodiversity

B2.7-Clasification & Biodiversity

There are 5 kingdoms,

Animals Multicellar

Plants All Green Plants

Fungi Mushroom,Yeast

Prokaryotes Bacteria,Blue Green Algae

Protoctist Amoeba,Chlorella,Plasmodium

Bacteria,

Single Celled Organisms,

Plants,

Fungi,

Animals,

Organisms have morphological and behavioural adaptations which enable them to survive in their enviroment.

Non Flowering Plants,Do not produce flowers e.g. ferns and mosses.

Flowering Plants,Produce flowers.

Invetebrates,Do not have a backbone e.g. insects.

Vertebrates,Have a backbone.

Birds,Lungs,Feathers,Beaks

Mammals,Lungs,Fur

Fish,Absorbs oxygen through gills,Wet scales

Reptiles,Lungs,Dry skin,Fur

Amphibians,Lungs,Absorbs oxygen through moist skin

King,Prawn,Curry Or Fried Greasy Sausages

Kingdom,Animals,Able to move on their own.

Phylum,Chorodates,Have a backbone.

Class,Mammals,Chorodates with fur,hair and milk glands.

Order,Primates,Have a collar bone and grasping fingers.

Family,Hominid,Primates with a realtively flat faces and three dimensional vision.

Genus,Hominds with an upright posture and large brain 

Species,Homo Sapiens,Members of the genus Homo,high forehead and thin skull bone

A quadrat is a wooden or plastic square.

Obtain valid data by

Repeating,

Random sampling,

Count number of organisms in the quadrat.

Sampling along a transect shows how the numbers of organisms change as we move across a habitat.

A transect is a line such as,a tape measure or piece of rope.

We use a quadrat to count the organisms at intervals on the transect.

Scientist call this the capture/recapture method.

Method

1st Take a sample of the population.

2nd Mark the item in the sample and return them.

3rd Take a second sample.

4th See what fraction are marked.

Possible Issues

None of the population have left.

Assume no new arrivals.

Assume no deaths or births.

Assume tags remain in tackt.

Equation

Population Size=1st Capture Times 2nd Capture Devided by the Amount Marked

Humans Fight For

Food,

Water,

Shelter,

Companionship,

Competition

Competition between different species,Interspecific Competition.

Competition between the same species,Intraspecific Competition.

Less competive species may face problems such as,

Having to move to another area,

Adapt to new survival stratagies,

Become extinct in that area,

Individual organisms need resources from the enviroment e.g. 

Food,

Water,

Light,

Minerals,

The size of the population may be effected by competition for these resources along with predation,disease and pollution.

Biodiversity provides food,potential foods,industrial materials,new machines for humans well beimg.

Biodiversity and endangered species can be protected by,

• Local biodiversity action plans,
• Seed/Sperm banks,
• National Parks,
• Breeding programmes,
• Specific intrest,
• Covection on International Trade in Endangered Species,

Biological control is the issue of introducing ailen species and their effects on local wildlife.

Some species have been introduce deliberatley and accidentally in to area where there not suppose to be, some have become invasive and cause problems.

Invasive species may grow faster than native species upseting the eco system.

Native species may not be able to compete with them.
