What is the ratio of plants to animals in the Riparian Forest?
2:1
(6.8:3.4 simplified)

The plant and animal data is averaged across many groups. Why did we average our data?
Averaging data strengthens our claim by including results from many samples, not just one. One way of adjusting for error.

Energy is lost between each step of the food chain. 90% of energy is "lost" or used in acts of daily living, and only 10% is passed to the next consumer in the chain. This is known as the...
10% rule.

We averaged our data for plants and animals. Why do the averages not make sense?
You can't have 7/10ths of a plant in real life USING OUR SAMPLING METHOD.

This type of animal gets its energy by eating other animals

Using the 10% rule, if there are 2 eagles in this ecosystem, about how many snakes must there be?
2 eagles x 10 = 20 snakes

On our second hike, we threw a hoop down and counted the number of biotic factors inside. Why does this sample under-represent the true number of consumers in an ecosystem?
Many answers:
-scared them off
-too small of a hoop
-inexperience of samplers
