Forest
Food web of forest biome
The primary consumer of this food web would be the deer. The deer consumes berries, grasses, seeds, and other plants, making it an herbivore. The secondary consumer would be the hawk. It only consumes plant-eating animals. There isn't exactly a tertiary consumer of this food web. The closest to it would be the bear, since it will eat the secondary consumer, but does not primarily focus on them. The producers of this food web are the berries, grasses, and other plants. They produce their own food using sunlight, water, and the chemicals around them. The decomposers of this food web would be the worms and fungi. They break down the cells of dead plants and animals into simpler substances.
Mutualism
Morels, a type of decomposive fungi, attach themselves to the roots of plants. This attachment increases the plants' absorption capacities, and helps morels derive nutrition from the plants' roots. Both plants are benefited from this.
Commensalism
A squirrel makes it's home inside of a tree. This benefits the squirrel, while the tree is left unaffected.
Parasitism
A flee drinks the blood of this deer. This benefits the flee, but hurts the deer.
Humans' impact on forests
Humans are positively impacting forests by planting more trees, using less polutive sources of traveling (i.e. bikes, walking), and cleaning the rivers or lakes that run through these ecosystems. Humans are negatively impacting forests by poluting them with nutrients and garbage that halt the production and growing process.
Hawk
The hawk is a carnivorous consumer that mainly hunts small animals such as squirrels or chipmunks. The hawk plays the role of the secondary consumer in the forest biome.
Deer
The deer is an herbivore that mainly eats grasses, berries, and flowers. It plays the role of the primary consumer in the forest biome.
Bear
The bear is a carnivorous animal that will eat anything it can reach. It's the organism that is the closest to a tertiary consumer in it's food web.
