The mountains

Biotic Factors

Animals include African Buffalo, African wild dogs, Alpaca , American  Black bear, Bison

Plants include Chaparal bushes, Ferns, Herbs, and willow also grow along the mountain

Abiotic Factors







Changes in population

The carrying capacity of a biological species in a environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.

Mountain goats eat grasses, sedges, herbs, shrubs, if those plants were to die the mountain goats would not have anything to eat causing them to starve to death, killing the population causing a decrease in the species.

Limiting factors

In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors like competition for resources, predation and disease can also impact populations. If any of the limiting factors change, animal and plant populations change, too.

Black Bears hunt Bull elk and they have to adapt to be able to catch them fast enough.

Energy roles

Producers= grasses, shrubs,mosses.                                                                               Primary consumers=  Moose                                                                                            Secondary Consumers= Bald eagle                                                                                  Tertiary consumers= Bobcats, Mountain lions, Black bears

Each organism receives its energy from the organism below it for example : Grass to Butterfly Butterfly to rabbit rabbit to tiger.

Producers are vital to the ecosystem because they transfer the suns radiant energy into chemical energy and that goes to the consumer.

Food chains and Food webs

Food webs show multiple food chains in one thing.

If i took away a animal it would trigger a chain event killing one animal so on so on.

Trophic prymid

The producers have the most energy starting at 10,000 then the herbivores get 1000 consumers get 100.


6CO2 + 6H2O ------> C6H12O6 + 6O2


Geo tropisims on a plant and trees phototropism

Geo tropism pushes roots toward dirt and soil and leaves towards the sun.


Decomposers break down dead plants and leaves and a bunch of other stuff without them we would not be able to store biomass. Worms Dung beetles moss.


THe types of adaptations include hibernating migrating.The mountains can be a barrier to both plants and animals due to rapidly changing ecosystems, harsh climates, scarce food and treacherous climbing. For this reason, either side of any given mountain range can be home to entirely different plant and animal species. However, plants and animals that do reside in the mountains have adapted in many ways to survive in harsh conditions. The most significant adaptations of plants and animals are seen at higher elevations, as these areas offer the most extreme conditions.

Natural selection

Natural selection is the gradual process by which heritable biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. It is a key mechanism of evolution. Black bears are an example of natural selection because they have thick fur for the winter and can climb trees and other things ver easily.

Looks good...see if you can be a little more specific with the abiotic factors.
