Acadia National Park
Transcript of Acadia National Park
Competition in community:
The bear and the fox are living in the same community and are competing for the same food because they are both carnivores and use the same resources.
Forest fires can effect the ecosystem by making animals fight each other to get the nutrients and living space they need to survive.

A food chain:
is a single line of organisms, where each is followed by something that it consumes
A food web:
branches out in all directions with arrows pointing from organisms to any number of organisms that consume it.
Producers consume energy from the sun.
consumers produce energy from eating
Energy through living systems:
When the grass is eaten by a rabbit the energy from the grass is given to the rabbit. When the rabbit is eaten by the fox the energy is transported to the top of the food chain and the process is repeated.
A deer's job is to provide energy for carnivores.
predation and keystone:
A fox would want to live by a rabbit, but a rabbit would not want to live next to the fox. This would effect the community by making them move from place to place.
can be harmless, However there are many situations of parasitism, or harmful symbiosis, in nature. One example of parasitism in Acadia is the deer tick. The adult female deer tick (parasite) attaches itself to a white-tailed deer (host), with its feeding tube. Adult female deer ticks need enough blood to spawn their 2000 eggs. Deer ticks are so reliant on white tailed deer to survive that changes in deer population can affect the number of ticks.
Though deer do not die unless infected with thousands of ticks, the bugs still do harm by sucking the deer's blood, making this a parasitic interaction.
