Invertebrates
- vertebrates-animals
with backbones
- fish-exchange
oxygen and
carbon dioxide
through gills, lay
eggs fertilised
externally
- amphibians-exchange
gases through their moist
skin, lay external
fertilised eggs
- reptiles and birds-
exchange gases
through lungs, lay
internally fertilised
eggs
- mammals-give birth to
live young, eggs are
fertilised internally
- Species
- organisms that can breed
together to produce fertile
offspring can be asexual
or sexual reproduction
- some species can
breed with other
species to produce
hybrids which are
sometimes sterile
or infertile
- Binomial
Classification
- every species has a
unique binomial name
- useful as everyone
knows exactly what
species you mean
without confusion
- genus name
tells you what
other species it
is closely
related to
- allows scientist
to communicate
about the
thousands of
species easier
- recognise areas of
low biodiversity which
need protection
