What are three pieces of evidence that lend support to global climate change (global warming) or increased average temperatures?
Polar ice cap melting, sea level rise, extreme droughts, increased carbon dioxide levels in the atmosphere, severe weather patterns
What type of population growth is shown in this graph?
What type of population growth is shown in this graph?
Exponential growth
If birth rate and immigration exceed death rate and emigration, what happens to the size of a population?
If birth rate and immigration exceed death rate and emigration, what happens to the size of a population?
The population increases.
What is a biotic factor? Name two biotic factors that can limit the population size.
What is a biotic factor? Name two biotic factors that can limit the population size.
Biotic factors are living factors that can affect an organism. Two examples of biotic factors that can dcrease the size of a population are predation and disease.
Using this population graph, explain what is happening to the size of this population
Using this population graph, explain what is happening to the size of this population
The population is not increasing or decreasing, It is staying the same size.
What type of growth curve is depicted in this graph? What does the red line represent?
What type of growth curve is depicted in this graph? What does the red line represent?
This is logistic growth and the red line indicates the carrying capacity.

Mutualism
What are the three generlized type of organisms that all food webs have?
What are the three generlized type of organisms that all food webs have?
Producers, Consumers and Decomposers
Identify the types of organisms that are found in the first, second and third trophic levels of a food web. Give an example of an organism at 1st, 2nd and 3rd trophic levels of a food web found on PK Yonge campus.
Identify the types of organisms that are found in the first, second and third trophic levels of a food web. Give an example of an organism at 1st, 2nd and 3rd trophic levels of a food web found on PK Yonge campus.
1st trophic level = producers (grass, alage, trees, bushes); 2nd trophic level - primary consumers or herbivores (grasshoppers); 3rd trophic level = secondary consumers or carnivores (bird, frog)
