Forest
My food web shows how different animals in a forest get their energy. If we were to destroy these energy sources the animal may not be able to live. We do this all the time, or we put animals in danger like, Tigers, Polar Bears, Ect. Primary- rabbit, secondary- snake, tertiary- hawk, producer- grass, decomposer- bacteria
How humans impact the environment.
One way humans impact the environment in a negative way is by, taking away the resources these animals need to survive.
One way humans impact the environment in a positive way is by, keeping things balanced.
Mutalism
Both are benefited.
Relationship between a deer a bird, the bird gets food while eating the insects off the deer. The deer gets rid of unwanted insects.
Parasitism
One is benefited, the other is harmed.
Relationship between a tapeworm and an animal. The tapeworm takes nutrients from the animal, and the animal is being hurt by this.
Commensalism
One is helped, the other is unaffected.
Relationship between a squirrel and a tree. The squirrel gets shelter and protection from predators. The tree is not harmed nor benefited.
