What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What are pioneer organisms?

Back

Pioneer organisms are the first species to colonize previously disrupted or damaged ecosystems, initiating the process of ecological succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, while secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact.

Front

What role do lichens play in succession?

Back

Lichens are often pioneer species that help break down rock into soil, facilitating the establishment of other plant species.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession, characterized by a diverse array of species.

Front

How does predation affect population dynamics?

Back

Predation can regulate population sizes by controlling the number of prey species, which can lead to increases in predator populations when prey is abundant.

Front

What is the significance of mangrove ecosystems?

Back

Mangrove ecosystems provide critical habitat for various species, protect coastlines from erosion, and serve as nurseries for fish.

Front

What is the role of competition in ecological communities?

Back

Competition occurs when two or more species vie for the same resources, which can influence population sizes and community structure.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water within the Earth and atmosphere, involving processes such as evaporation, condensation, and precipitation.

Front

What is the heterotroph hypothesis?

Back

The heterotroph hypothesis suggests that the first living organisms were heterotrophs that obtained energy by consuming organic compounds.
