The Producers of this ecosystem are the diatoms, filmentous algae, and macrophyte which get there energy from the sun. Primary consumers are consumers that eat the producer. The primary consumers in this ecosystem are the malfly and the pond snail. Secondary consumers are carnivores that eat the primary consumers and the decomposers, the secondary consumers in this ecosystem are the diving beetle and the hawkers dragonfly. The decomposers of this ecosystem are the malfly and the worm and they decompose the detritus. A tertiary consumer eats the secondary consumer, the tertiary consumer is the pike. Lastly at the top of this ecosystems food chain, is the heron which eats the pike.
Symbiotic relationships: mutalism
Mutualism is when two species benefit from a relationship. For example in the movie finding nemo the clown fish has a natural relationship with the anemone. The clown fish protects the anemone from fish that eat anemones and in return the anemone protects the clown fish from predators.
The next type of relationship is parasitism. That is when one thing depends on another but the person the parasite depends on is not benefited. Example: when a flea is feeding off a dog the flea is benefited but the dog is not.
Commensalism is a relationship between two living organisms where one benefits and the other is not harmed or helped. For example when a spider builds a web on a plant this spider is benefited and the plant is not benefited or affected.
How humans impact the environment
Many can debate on how humans impact this environment. Some ways humans positively impact the environment is by doing clean up projects for lakes and rivers, fish for food to keep the population down, and make sure that the population is growing at a good rate. Some ways that people negatively impact this ecosystem is by littering, pouring toxins down the drain, and polluting the water with pesticides.
