Ecological succession...

Back

A series of changes where new species gradually colonize an area, leading to a stable ecosystem.

Front

Primary succession...

Back

Primary succession occurs on surfaces where no soil or organisms exist.

Front

Pioneer species...

Back

Pioneer species, such as mosses and lichens, help build soil by breaking down rock and adding organic material.

Front

Stable ecosystem involves several stages...

Back

After pioneer species, more complex plants and animals move in, eventually leading to a diverse and stable community.

Front

Secondary succession...

Back

Restarts from existing soil and seeds, roots, or young left by organisms that died. It increases species variety over time.

Front

Secondary succession can occur due to natural events or human activities.

Back

Natural events include wildfires, floods, tsunamis, hurricanes, and tornadoes. Human activities include wildfires, abandonment of fields, and logging.

Biodiversity

Back

Biodiversity is the number and variety of different species in an area and the variations within species. It includes genetic, species, and ecosystem diversity.

Front

Importance of Biodiversity

Back

Biodiversity is essential for the health of ecosystems. It contributes to stability and sustainability, allowing ecosystems to withstand disruptions and maintain balance over time.

Front

Keystone Species

Back

Keystone species, like bees, are crucial for the health of ecosystems. They connect various organisms, and changes affecting them can impact the entire ecosystem.

Role of Pollinators

Back

Pollinators, such as bees, are keystone species that help plants reproduce by bringing pollen to flowering plants. They are vital for the health of animals that depend on plants for energy.
