Organization of Ecology
List 2 Biotic factors
living examples
Term describing the study of life
ecology.
Give one example of an autotroph and one example of a heterotroph.
Autotroph: Plants
Heterotroph: Animals, insects, bacteria, fungi
Define Carrying Capacity
The maximum population an ecosystem can sustain
Why do we study ecology?
Provides new knowledge between people and nature.
All of the same species that live in an area
population
An organism that can produce its own food
An organism that can produce its own food autotroph
Draw a food chain
Grass
Rabbit eats grass
Raccoon eats rabbit
Wolf eats raccoon
Grass --> Rabbit --> Raccoon --> Wolf
Give an example of
Density Dependent limiting factor:
Density Independent Limiting Factor:
Dependent: Food, water, shelter
Independent: Natural Disaster
What are the types of ecology?
Organisms, communities, population and ecosystem.
List 4 factors that would belong to a community
Only living factors
The role, or way of life of a species within its environment.
niche.
Bush --> Deer --> Fox --> Coyote
What is the tertiary consumer
Coyote
A population of bees moved into a new ecosystem. There is already a large population of bees in this area. The bees are competing for the flowering plants nectar. What type of limiting factor is this?
Density Dependent
When did ecology become popular?
1960's
List 6 factors that would belong to an ecosystem
must list biotic and abiotic factors
Only one species benefits without harming or benefitting the other.
commensalism
bush --> deer --> Fox --> coyote
If the deer passes 13,000 kCal of energy to the fox, how many kCal will the coyote gain from the fox?
1300
An irresponsible camper did not put out their campfire properly before leaving their campsite. The fire quickly spread through the forest because of the recent droughts. Many populations perished in the fire. What type of limiting factor is this?
Density Independent
What is the difference between ecology and ecosystem?
Ecology is the study between living organisms and their environment, ecosystem is the place where interactions between non-living and living things occur.
Coyotes are opportunistic predators that are found throughout most of North America. They typically feed on small mammals, insects, and fruits and vegetables. They are known for their dietary adaptability. The best description of their role in the food web would be:
Omnivore
Cover large areas and are characterized by their climate and the types of plants and animals that are found there.

Bush --> Deer --> Fox --> Coyote
Place this food chain in an energy pyramid. Label the consumers and producer.

Use picture #3 to answer this question
What is the estimated carrying capacity for the deer population?
What would you predict would happen to the carrying capacity if a drought reduced the producers available?
about 80
The carrying capacity would decrease
What is the main branch in ecology?
Terrestrial Ecology.
