What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption, leading to the establishment of a biological community.

Front

Give an example of primary succession.

Back

Lichens growing on rocks following a volcanic eruption is an example of primary succession.

Front

What is a pioneer species?

Back

A pioneer species is the first species to colonize previously disrupted or damaged ecosystems, such as lichens in primary succession.

Front

What role do lichens play in primary succession?

Back

Lichens help break down rocks into soil, facilitating the growth of other plants.

Front

What is ecotourism?

Back

Front

What is a microhabitat?

Back

A microhabitat is a very small, specialized habitat within a larger ecosystem.

Front

What is genetic diversity?

Back

Genetic diversity refers to the variation of genes within a species or population in a given area.

Front

Why is genetic diversity important?

Back

Genetic diversity is important for the survival and adaptability of species, allowing them to cope with environmental changes.
