Eutrophication & Succession

Front

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 gradual establishment of an ecosystem.

Front

What is succession in ecology?

Back

Succession is the gradual process of change and replacement in the species composition of an ecosystem over time.

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

How does thick algae affect photosynthesis?

Back

Thick layers of algae block light, which is essential for photosynthesis in aquatic plants.

Front

Can eutrophication occur in rivers?

Back

TRUE - Eutrophication can occur in both rivers and lakes.

Front

What is the growth rate of algae?

Back

Algae grows at a very rapid rate, often leading to algal blooms.

Front

What are the main causes of eutrophication?

Back

The main causes of eutrophication include runoff from fertilizers, sewage discharge, and industrial waste.

Front

What is a secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where an ecosystem has been disturbed but soil and some organisms still exist.

Front

What role do decomposers play in succession?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and facilitating the growth of new plants during succession.

Front

What is an example of primary succession?

Back

An example of primary succession is the colonization of a new volcanic island by lichens and mosses.
