Biology/bio3
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

BIOLOGY 3
1 FOOD CYCLES
Organisms need energy for activities
and for growth. They also need
materials for growth. Only green
plants can use the sun's energy to
make molecules from which energy can
be obtained: other organisms depend on
photosynthesis by plants. Green plants
are 'producers', other organisms are
'consumers'. They are related by FOOD
WEBS, CARBON and NITROGEN CYCLES.
#
2 FOOD WEB
A green plant will be eaten by a
herbivore (PRIMARY consumer) which is
eaten by a carnivore (SECONDARY
consumer).
This is a food chain. A food web is a
network of food chains in a particular
habitat.

5 FOOD CHAIN
In any food chain, energy is lost at
each step. Only about 10% of the
energy in food is built into living
tissue and is therefore available to
the next link of the chain as food,
so food chains are only 3-4 organisms
long. There is always a fall in
numbers (or biomass) as shown.
PYRAMID OF NUMBERS
Bars show population or biomass,
figures show relative energy.
