Which statement best describes ecological succession

Question: Which statement best describes ecological succession?

a) It is always caused by human intervention.
b) It occurs after a disturbance.
c) It never occurs in a predictable pattern.
d) It is a series of rapid changes in an ecosystem.

Answer: It occurs after a disturbance.

Explanation

Ecological succession is the gradual and inevitable changes in plant and animal communities as a result of natural processes. Disturbances such as fire, floods, hurricanes, and avalanches may trigger the process.

Ecological succession occurs after a disturbance. One type of disturbance is an environmental stressor. An example would be increased temperatures that create increased evaporation rates which leads to water depletion. This will eventually impact an area’s vegetation and wildlife by impacting their ability to access water for hydration and digestion.

The disturbances also affect the soil composition which will impact how much organic matter can grow in that area’s soil and how much available sustenance there is for any living beings residing in the area.

The rate of succession is also impacted by the severity of the disturbance. The more severe the disturbance, the less time it takes for the new community to become established.

In general, there are five stages of ecological succession:

1) Initial colonizers – These are the first plants and animals to arrive after a disturbance. They are often hardy and versatile species that can tolerate a wide range of environmental conditions.

2) Establishment – The initial colonizers will start to grow and spread, forming larger and more complex communities.

3) Maturity – The community will reach its full size and stability, with the various plant and animal species occupying specific niches.

4) Stagnation – The community will remain stable for a period of time, often many decades. There is no net change within the community during this time.

5) Decline – The environment has reached the end of its lifespan for hosting that particular kind of plant and animal community. At this point, another disturbance would be necessary in order to start the process all over again.

What are the three types of ecological succession?

There are three types of ecological succession: primary, secondary, and tertiary.

Primary succession is the process of colonization by plants and other organisms in an area where there was previously no life. This can happen when a new area is created, such as when a volcano erupts and creates a new landform, or when an area is damaged by a natural disaster or human activity.

Secondary succession occurs after a disturbance, such as a fire or the death of the dominant species in an ecosystem, and is driven by smaller plants called pioneer species.

Tertiary succession happens as a forest matures and creates its own unique conditions through the process of ecological succession.

Primary Ecological Succession

What is primary succession?

Primary succession is the process of colonization by plants and other organisms in an area where there was previously no life.

What are some examples of primary ecological succession?

Some examples of primary ecological succession include when rocks, soil, or lava break down through weathering to create soil that can then support plant life.

This can happen when a new area is created, such as when a volcano erupts and creates a new landform, or when an area is damaged by a natural disaster or human activity.

What are the main causes of primary succession?

The main causes of primary succession are physical factors such as weathering, water and wind erosion, and the presence of water and nutrients in the soil.

Secondary Ecological Succession

What is secondary succession?

Secondary succession occurs after a disturbance, such as a fire or the death of the dominant species in an ecosystem, and is driven by smaller plants called pioneer species.

What are some examples of secondary ecological succession?

Some examples of secondary ecological succession include when a forest fire kills all the trees in an area, or when a hurricane damages an ecosystem.

What are the main causes of secondary succession?

The main causes of secondary succession are biological factors such as the arrival and growth of pioneer species, and the competition for resources among plants.

Tertiary Ecological Succession

What is tertiary succession?

Tertiary succession happens as a forest matures and creates its own unique conditions through the process of ecological succession.

What are some examples of tertiary ecological succession?

Some examples of tertiary ecological succession include when an old-growth forest matures over time, or when plants grow in abandoned agricultural fields.

What are the main causes of tertiary succession?

The main causes of tertiary succession are physical factors such as weathering, water, and wind erosion, or the presence of water and nutrients in the soil. The main factor is climate change over time because it affects all other processes that happen during ecological succession.
