Freshwater biome
Amazon River foodweb
This is a fresh water bike foodweb, specifically the Amazon. The producer is algae which get its energy from the Sun. My primary consumers that eat the algae are Daphnia, Giant river turtle, Apple snail, and Angel Chichlid that eat the algae. Secondary consumer are River Otters and Piranahs that eat the Angel Chichlid, and Daphnia. My tertiary consumer is the Pink River Dolphin. Lastly I have my decomposed who eats everything.
Symbiotic relationships
Mutualism
In this relationship both organisms benefit. An example is an Angel Cichlid eating algae. The fish gets its energy and the algae's population will stay under control.
Commensalism
One organism in this relationship benefits and the other is unharmed and unaffected. In a freshwater biome a small fish may hide in a plant from its predators.
Parisitism
In this relationship one organism benefits and the other is harmed. An example is a parasite on a fish. This hurts the fish but helps the parasite.
Pink River Dolphin
This rare dolphin species is a tertiary consumer that eats a variety of fish and snails. It will even eat Piranahs.
Angel Cichlid
This fish is a primary consumer and eats algae and also eats Daphnia.
Daphnia
Daphnia is a crustacean first level consumer that eats algae. This organism is eaten by a variety of small fish.
Human Impact
A positive way humans may impact the environment is making laws that protect the fish by limiting how much people can fish in certain areas. Some negative ways could be runoff and pollution. If someone leaves a plastic bag or uses to much fertilizer in their lawn. It will eventually make its way to lakes, rivers, and oceans. Causing algae blooms and hurting the fish.
