How does secondary succession differ from primary succession in terms of species diversity?

• Secondary succession typically has higher species diversity from the beginning.

• Primary succession reaches higher species diversity more quickly.

• Both reach the same level of species diversity at the same rate.

• Primary succession typically has more initial species diversity.

In a scenario where both primary and secondary succession occur simultaneously, which of the following would

you most likely observe first in the secondary succession?

• Soil formation

• Appearance of mosses and lichens

• Growth of grasses and small shrubs

• Development of climax community

What is likely a consequence of a disturbance that destroys the existing plant community but leaves the soil intact?

• The area will undergo primary succession

• The area will revert to a climax community immediately.

• The area will experience secondary succession.

• The area will become a barren wasteland.

Which of the following is most likely to be a pioneer species during primary succession?

• Oak trees

• mammals

• moss

• Shrubs

In the process of ecological succession, what role do decomposers play?

• They fix nitrogen in the soil.

• They break down dead organic matter, enriching the soil.

• They provide energy for primary producers.

• They prevent the growth of pioneer species.

Which type of forest is typically found on tidal flats and serves as a buffer against typhoons and waves?

• Dipterocarp

• Mangrove

• Molave

• Mossy

What is deforestation?

• Planting trees in a barren land

• The large-scale removal of forests

• Increasing the size of forest reserves

• Reforesting cleared land

What is one of the natural causes of deforestation in the Philippines?

• Commercial logging

• Mining operations

• Volcanic eruption

• Agricultural expansion

Which of the following is a common effect of deforestation?
