Estuaries
Estuaries Food Web
In this food web you have what we is called a Parasitism which is a symbiotic relationship. Which is where one organism is benifited while the other is harmed.
Commensalism
Commensalism Is when both organisms are safe. Here the crocodile is getting his teeth clean by the bird. No one is harmed at all.
Mutualism
Mutualism Is when both organisms are benefited. As you can see we used the same picture as the one from commensalism because it's a good picture for both. Here the crocodile is getting his teeth cleaned by the bird that's good for him. The bird is getting food from the crocodile's teeth, and that's good for him. Both are benefited in this situation.
Parasitism
Parasitism Is when one is benefited and unfortunately the other is harmed. Here you have the Lion killing the Zebra. The Lion is getting food, and the Zebras is the food
Animals and their roles in a food web.
You have the Sun, Eelgrass, Detritus, Clam, and a Human. The sun is a producer it's producing light and energy to the Eelgrass. Then the Eelgrass gets eaten by the Detritus then the Detritus gets eaten by the Clam, and obviously the Human eats the Clam.
How do humans impact in the environment?
Because they are transitional areas between the land and the sea, and between freshwater and saltwater environments, estuaries can be seriously impacted by any number of human, or anthropogenic, activities.
