Succession and climatic climax in a hydrosere

• What are the first organisms to colonize the water surface in hydrosere succession?

  Pioneer species such as algae
• What happens to algae after they die in the hydrosere process?

  They sink to the bottom and accumulate
• How does the accumulation of sediments affect the water in hydrosere succession?

  The water gets shallower as sediments accumulate
• Which plant species moves in after algae to trap more sediment at the bottom?

  Plants such as elodea
• What occurs as marsh plants move into the hydrosere environment?

  The water becomes very shallow
• What is the role of marsh plants in the hydrosere succession process?

  They generate litter that forms wet soil
• What happens to the soil as larger plants die and decompose in hydrosere succession?

  The soil becomes deeper
• Which type of plants move in after marsh plants in the hydrosere process?

  Larger plants such as ferns
• What is the final stage of succession in hydrosere?

  Climax tree species such as oak grow
• How does the dominance of climax tree species affect the hydrosere ecosystem?

  They become the dominant species in the area
• Succession in Hydrosere:

  • Pioneer species such as algae colonise the water surface
  • The algae die and sink to the bottom where they accumulate along with other sediments
  • The water gets shallower as sediment and decomposing plant material accumulate
  • Plants such as elodea move in and trap more sediment at the bottom
  • The water becomes very shallow as marsh plants move in
  • Marsh plants generate lots of litter which forms wet soil
  • Then larger plants such as ferns move in as the soil becomes deeper as larger plants die and decompose
  • Then climax tree species such as oak grow and become dominant
