Use the whiteboard below to draw a quick sketch of a
forest ecosystem
You must include:
• 3 biotic factors
• 3 abiotic factors
• 2 interactions between biotic and abiotic factors
• 1 example of 2 biotic factors competing for one abiotic factor
In your drawing, explain how the biotic and abiotic factors are interacting?
In your drawing, explain how the example of how 2 biotic factors (living things) are competing for abiotic factors (nonliving things)

Prairie dogs live in complex tunnels underground and compete with other herbivores in the ecosystem. Which is the abiotic factor (nonliving thing) in this situation?
Which is not an example of an abiotic factor?
Which abiotic factor(s) do plants compete for in order to make their own food?
Which is a true statement?
