Everything is Connected Unit 1: Seventh Grade
An alligator (Jump!) drifts along a river in Florida… He’s watching a fish (a gar). The gar swims too close… Then, in a rush of muddy water SNAP!!! Jump swallows the gar whole and slowly swims away Biotic factors? Abiotic factors?
It’s clear that Jump and the gar interacted… But organisms have any other interactions other than simply who is eating who. For example, Jump may dig a hole underwater to escape the heat. After the hole is abandoned, other organisms may live in the holes
