Transcript of The forest habitat includes many abiotic and biotic factors.

Limiting factors
Some limiting factors are that the animals in the forest are very particular about what they eat. So if a brown bear only has access to deer and blue berries the populations of those two factors will decrease, while the bear population increases. But eventually the bears population would decrease, due to loss of food sources.
Limiting Factors
Pyramid
If there was a change in the habitat there would be drastic effects on the wildlife living there.
Global warming can have quite a few negative effects on the forest habitats. It can cause drought,drought is an extreme lack of water for an extended period of time. If a drought were to take place it would cause a lot of death to both animals and vegetation. Water sources like streams would dry up, causing fish to die, and anything else that drinks from it.
Effects of Global Warming
The animals presented in my pyramid live in the terrestrial ecosystem, where there is a wide variety of food sources.
The terrestrial environment has many food sources to present. It offers nutrients to carnivores, herbivores, and omnivores. Carnivores are animals that eat only meat. herbivores only eat plant life, and omnivores eat both.
food sources
The forest habitat includes many abiotic and biotic factors.
some examles of abiotic factors are rocks, logs, water, and tree stumps. Abiotic factors are anything nonliving.
Abiotic
Drought Effects
The forest has an abundance of plant life that supply nutrients to both the herbivores and omnivores. For example the sun gives berry bushes the ability to preform photosynthesis and the berry bush feeds a white tailed deer. The nutrients is then passed to a carnivore when the deer is eaten.
Who eats Who
Some biotic factors in the terrestrial enviroment are brown bears, deer, beetles, grasses, bushes, and trees. Anything living can be classified as biotic.

Competition of Resources
In the forest there is a lot of competition, both intraspecific and interspecific. Intraspecific is when members of the same species compete. Interspecific is when different species compete.

Examples-
An example of intraspecific competition would be when two brown bears compete for the same deer or fish. An example of interspecific competition is a deer and a rabbit competing for the same berry bush.

Predator Prey Relationships
In the forest there are many predator and prey relationships. Predators are the organisms that eat the weaker organisms in their diet, the prey. A deer is the prey to a brown bear.


Changes In food Sources
If there is a change in a animals food source they have three options, adapt, migrate, or die. If this were to happen to a bear I think the species could adapt because they have a wide variety of what they can eat. With deer I think they would migrate to find a different food source (other vegetation) because plant life can be found in many different places.
