2. Species Diversity
Species diversity or species diversity is the diversity found among living things of different
types within one genus / genus. Examples of species diversity can be observed in the genus
Panthera. Within the Panthera clan, there are different types, including tigers, lions, cats,
leopards.

3. Ecosystem diversity

We find that every place has different environmental conditions. For example, coastal areas
have higher salinity than lakes. Therefore, living things that are able to live on the beach will be
different from those in lakes. Differences in biotic and abiotic components will cause differences
in ecosystems.
The variety of living things that exist in each ecosystem will cause diversity at the
ecosystem level. Ecosystem diversity is due to differences in the geographical location of each
ecosystem. In cold regions there is an ecosystem of tundra, which can live animals, including
wildebeest and polar bears. In tropical areas there are tropical rainforests, this area has a wide
variety of plants and animals.
