What are the different types of ecological disturbances?

• Climate disturbances and geological disturbances

• Biological disturbances and chemical disturbances

• Natural disturbances and human-induced disturbances

• Physical disturbances and social disturbances

How do ecological disturbances affect ecosystems?

• Ecological disturbances always lead to an increase in biodiversity.

• Ecological disturbances only affect the physical environment, not species composition.

• Ecological disturbances have no impact on ecosystems.

• Ecological disturbances can disrupt the balance of species and alter the physical environment, leading to changes in biodiversity, species composition, and ecosystem functioning.

What role do disturbances play in ecological succession?

• They prevent succession from occurring

• They have no impact on succession

• They can initiate or reset the succession process

• They speed up the succession process to reach the climax community faster

What, could make this ecosystem LESS stable?

• A disturbance that leads to ecological succession

• An invasive species

• Humans doing things to conserve the native habitat

Answer explanation

Those two things are included in HIPPCO, which tells us what is bad for ecosystems

Which of the following is an example of secondary succession?

• The formation of an island from volcanic activity

• The recovery of a forest after a wildfire

• The initial colonization of bare rock by lichens and mosses

• The introduction of fish into a new pond

Two types of ecological disturbance are:

• animals and plants

• abiotic and biotic

• natural and human-caused

• weather and climate

Answer explanation

The correct types of ecological disturbance are natural (such as wildfires or hurricanes) and human-caused (like deforestation or pollution).

If a disturbance of a flood impacts this ecosystem select two organisms that would be most impacted.
