How are organisms classified into groups?
According to similarities and differences in characteristics including: physical features (e.g. flowers in flowering plants and the skeleton in vertebrates) and DNA
1 of 12
Describe how organisms are classified at different levels
The largest group (kingdom) contains many organisms with a small number of characteristics in common progressing to smallest group (species) contains fewer organisms with more characteristics in common
2 of 12
Why are living and fossil organisms classified?
To make sense of the enormous diversity of organisms on Earth and show the evolutionary relationships between organisms
3 of 12
What is biodiversity?
The variety of life on Earth
4 of 12
What does biodiversity include?
1. The number of different species 2. the range of different types of organisms, e.g. plants, animals and microorganisms 3. the genetic variation within species
5 of 12
Why is biodiversity important?
For the future development of food crops and medicines
6 of 12
What is happening to the rate of extinction of species and why?
The rate of extinction of species is increasing and why this is likely to be due to human activity
7 of 12
What is one of the keys to sustainability?
Maintaining biodiversity to ensure the conservation of different species is one of the keys to sustainability
8 of 12
What is sustainability?
Sustainability means meeting the needs of people today without damaging the Earth for future generations
9 of 12
Why is large-scale monoculture crop production not sustainable?
because it does not maintain biodiversity
10 of 12
How can sustainability be improved when using packaging materials?
Using renewable materials, using less energy and creating less pollution
11 of 12
Why is preferable to decrease the use of some materials, including packaging materials, even when they are biodegradable?
Even biodegradable materials use energy in their production and transport and slow decomposition in oxygen deficient landfill sites.
