SUCCESSIONS AND
BIOMES
Lesson 3
, How does a biological community
develop?
A Biological Community is brought by a series
of natural changes and species replacements in
the existing communities in an ecosystem.
These observed changes within the ecosystem
occurring over time are called ecological
succession.
- Within a community, a species composition will
gradually change as some species become more
prominent whereas others do not thrive well and
die out.
There are two types:
- Primary Succession
- Secondary Succession
, Primary Succession
It basically takes place where there
are no existing organisms.
Ex.
When a barren piece of land such as
rock surfaces from landslides or lahar
flows becomes exposed and is
subject to colonization of plant and
animals
, Primary Succession
Pioneer Species is what you call to
the first colonizers.
Ex.
Lichen, which consists of an algae or
bacteria in a mutual relationship with
a fungus
