8.2 Colonisation and Succession in an Ecosystem
Transcript of 8.2 Colonisation and Succession in an Ecosystem
in an Ecosystem A community of organisms which interact with their non-living environment and function as a unit. Ecosystem A natural environment where organisms live. Habitat Food Habitat Shelter Living Space Nesting sites Mates A group of organisms that look alike and have similar characteristics. Species Population A group of organisms of the same species living in the same habitat at the same time Community Consist of several populations of different species living in the same habitat in an ecosystem Chapter 8: Dynamic Ecosystem An organism A population A community An ecosystem Colonisation and Succession Colonisation It takes place in newly formed areas where no life previously existed. The first plant species to inhabit a new place is called a pioneer species. The pioneer species change the new habitat slowly to make the habitat more suitable for other species to live in. As a result, the new habitat which is not suitable for the pioneer species is slowly replaced by another new species and succession begins. The successor species also change the structure and quality of the soil making it more conducive for larger plants to grow. The process of succession is a process in which a dominant plant species in a habitat is gradually replaced by another plant species ( successor species) The stable and matured community is called a climax community. Process of Colonisation and Succession in a Pond Colonisation and Succession in a Mangrove Swamp Avicennia and Sonneratia zone Can withstand salt water and the movement of the tides. Viviparous seedlings of Avicennia will be carried by the sea-current. The thick muddy bank is rich in organic matters. Rhizophora zone Stilt roots help Rhizophora to breath. The roots may support the trees in the soft mud. Brugulera zone Have viviparous seedlings for developing rapidly. The characteristics of leaves: - Hydathodes
- Thick, fleshy leaves
- Waxy cuticles END OF TOPIC 8.2 made by : Amanda Huang :)
