Ecology Assessment

Abiotic Factors Amount of WaterOxygen levels in water and air Temperature of water Clouds/weath er Amount of shelter

Biotic Factors Population of trees TreesPopulation of frogs (predator and prey) Population of algae Population of lily pads Population of predator birds

Limiting factors The amount of water is a limiting factor to the frogs that live in the environment because every frog needs a certain amount of water to live. This is because they need to stay moist because they are amphibians. If the amount of water drops the population of frogs will drop too.

R strategist One population if r strategist in this ecosystem are the mosquitoes. R strategists are short living and fast reproducing. They also reproduce a in large quantities

K strategists One k strategist population in this ecosystem would be the population of geese. K strategists are long living (compared to most r strategists), reproduce once in a while, and once impregnated take time to birth offspring.

This ecosystem is experiencing succession because there are plants growing through cement and the docks. There are also plants starting to succeed in the road in the back. Succession Analysis

One decomposer in the ecosystem is fly larvae. The eat dead animals. This decomposes them and returns the carbon through their wastes. They also return nitrogen to the soil through the decomposing of organisms.
