Explain how the disappearance of the Snake would affect its predator and prey
The kite population would decrease because it would be without food, and the mouse population would increase

the Grasshopper

Explain in detail why symbiotic relationships are a very important part of ecosystems
ecological relationships are important for ecosystems because species rely on one another for survival.

Explain what happens if an organism in a food chain dies off. How does that effect the food chain?
The food chain will be thrown off, some predators will be without food and that animals prey population will rise do to the lack of predators
500
As energy is moved up the energy pyramid, what happens to the amount of energy being transferred?
Energy is lost during each transfer so apex predators receive less energy than animals lower on the food chain

If the population of Fox were to increase due to the large amounts of prey, what would happen? (Think about our predator vs. prey game outside!)
The rise of the fox population will actually be their downfall. When populations rise, there eventually wont be enough food to go around- then the population will decrease due to lack of food.
