Secondary succession generally occurs more rapidly in an area than does primary succession because soil formation has already occurred.
Explanation:
- Primary succession is the sequential change in environment and community which is a new habitat for example,the formation of an island.
- Similarly secondary succession is also the change in environmental factors that occurs in a disturbed community which has been colonized already.
- Secondary succession always starts after the primary succession so it generally occurs faster that primary succession.
- For example the formation of soil is the primary succession for a new habitat that makes the secondary succession faster.

Answer: B. collar cells and amoebocytes
The collar cells have a funnel like collar and a flagellum. Collar cells whip their flagella to make water go through the sponge. Then the water brings nutrients and oxygen, while while also taking out waste and carbon dioxide.
Amoebocytes first deliver nutrients from choanocytes to the other cells, giving rise to eggs. Then they bring phagocytized sperm from choanocytes to eggs.
