Prediction:
A bear population relies on trout as their main energy source. But an oil spill just happened in the river the trout are living in. What do you think this will do to the trout and bear population?
The oil spill will either kill off the trout population or the trout will ingest the oil making them toxic and unhealthy. The bears will not have a food source.
The third level of consumers on an energy pyramid are called?
Tertiary Consumers
