Now, consumers are coming in. There are more producers and consumers such as mice and other small creatures.
A bit larger creatures are starting to come, changing this to a stage of climax community. Trees are starting to grow, and now thereis a larger population.
We have now reached climax community, tall trees are growing and we have a perfectly balanced ecosystem. Since trees are larger, it blocks the sunlight and now small plants are beginning to disappear. Homeostasis will occur and now the ecosystem won't be having large changes. Making it sustainable for a while.
