What is the term for the gradual change in the composition of a community over time?

  1. Ecological Succession

  2. Evolution

  3. Adaptation

  4. Migration


Correct Option: A
Explanation:

Ecological succession is the process by which a community of organisms changes over time, as new species enter and others leave.

Which of the following is NOT a stage in ecological succession?

  1. Pioneer Species

  2. Climax Community

  3. Secondary Succession

  4. Primary Succession


Correct Option: C
Explanation:

Secondary succession is a type of ecological succession that occurs after a disturbance, such as a fire or flood, has cleared an area of vegetation.

What type of species are the first to colonize an area after a disturbance?

  1. Pioneer Species

  2. Climax Species

  3. Secondary Species

  4. Tertiary Species


Correct Option: A
Explanation:

Pioneer species are the first to colonize an area after a disturbance because they are adapted to harsh conditions and can survive with few resources.

What is the final stage of ecological succession?

  1. Pioneer Species

  2. Climax Community

  3. Secondary Succession

  4. Primary Succession


Correct Option: B
Explanation:

The climax community is the final stage of ecological succession, and it is characterized by a stable and diverse community of organisms.

What is the difference between primary and secondary succession?

  1. Primary succession occurs on bare rock or soil, while secondary succession occurs after a disturbance.

  2. Primary succession occurs after a disturbance, while secondary succession occurs on bare rock or soil.

  3. Primary succession occurs in water, while secondary succession occurs on land.

  4. Primary succession occurs on land, while secondary succession occurs in water.


Correct Option: A
Explanation:

Primary succession occurs on bare rock or soil, while secondary succession occurs after a disturbance, such as a fire or flood, has cleared an area of vegetation.

What is the role of pioneer species in ecological succession?

  1. They provide food and shelter for other species.

  2. They help to stabilize the soil.

  3. They help to create a more diverse community.

  4. All of the above


Correct Option: D
Explanation:

Pioneer species play a vital role in ecological succession by providing food and shelter for other species, helping to stabilize the soil, and helping to create a more diverse community.

What is the role of climax species in ecological succession?

  1. They are the first to colonize an area after a disturbance.

  2. They are the final stage of ecological succession.

  3. They are adapted to harsh conditions and can survive with few resources.

  4. They are responsible for the majority of the biomass in a community.


Correct Option: B
Explanation:

Climax species are the final stage of ecological succession, and they are characterized by a stable and diverse community of organisms.

What is the importance of ecological succession?

  1. It helps to maintain biodiversity.

  2. It helps to cycle nutrients through the ecosystem.

  3. It helps to create new habitats for wildlife.

  4. All of the above


Correct Option: D
Explanation:

Ecological succession is important because it helps to maintain biodiversity, cycle nutrients through the ecosystem, and create new habitats for wildlife.

What are some of the factors that can influence ecological succession?

  1. Climate

  2. Soil conditions

  3. Disturbances

  4. All of the above


Correct Option: D
Explanation:

Climate, soil conditions, and disturbances are all factors that can influence ecological succession.

How can humans impact ecological succession?

  1. By introducing invasive species

  2. By clearing forests

  3. By polluting the environment

  4. All of the above


Correct Option: D
Explanation:

Humans can impact ecological succession by introducing invasive species, clearing forests, polluting the environment, and other activities.
