If you change more than one variable at a time, then you will have a harder time trying to figure out why the certain change occurred.
Answer:
Biome 1: Arctic Tundra
Organism 1: Arctic Fox
Explanation:
1. This organism can be found in a cold, snowy ecosystem with long winters and short summers.
2. The Arctic Fox is at the top of the food chain, so it has a small amount of predators. It's population would increase if there were no predators to hunt them. This would affect the ecosystem by causing a sudden decrease in the Arctic Fox's prey.
