Ecosystem (Succesion)

Interactions of community of organisms (biotic) with the abiotic parts of the environments

All the population of different species living in the same habitat

Changes over time as population fluctuates

New species successively colonise an area and may change the environment to They make it less suitable for existing species and make it more suitable with other species with different adaptations ( Enable species to out-compete) Results in less hostile environment Forms new communities Starts with a pioneer species

1) Inhospitable environment colonised by pioneer species 2) Death + decomposition of pioneer species form soil and releases nutrients to change the environment 3) Enable other species to colonise in succession 4) Change biodiversity as stability decreases 5) Climax community forms

Stable community with same species present Abiotic factory constant over time Population stable

The active management and protection of an ecosystem and its natural resources to maintain species, habitats and biodiversity (Involves managing succession to preserve habitats and their species to prevent formation of climax community)
