What is ecology?

the study of how living organisms interact with one another and their surroundings

100

What are the Earth's Main Cycles 

  • Carbon cycle , Water cycle , Nitrogen cycle, Phosphorus cycle 

100

What is the difference between an autotroph and a heterotroph?

Autotrophs makes their own food for energy 

Heterotroph needs to eat/ consume food for energy 

100

Which is an example of Density Dependent and Density Independent. ( tsunami, Disease, weather, Biotic factors) 

D.D = 

D.I= 

D.D = Disease, Biotic factors

D.I = Tsunami ( natural disaster) , weather

What is an example of a pioneer species?

ex. producers known as (lichens, grass)

Categorize what are Abiotic and Biotic :

Sun,Hippo, Human, wind, rock, dead tree

Abiotic : Sun, Wind, Rock

Biotic : Hippo, Human, Dead tree

What is carrying capacity?

the maximum number of individuals in a species that an environment can support for the long term

300

Give an example of something that adds CO2 to the atmosphere, and an example that takes it out of the atmosphere.

Adds CO2- something living that dies, fossil fuels, when animals breathe out.

Takes Out- Trees
