Answer: Food, water, oil, gas, and wood
Step-by-step explanation:
From the eggs from the chickens, apples from the trees, without natural made food, we wouldn't be able to survive. Water as well, of course, since we depend on these to survive.
We also need gas for transportation, and oil for food, cars, cooking, and way more. Without them we wouldn't be able to go the places we want to go, we wouldn't be able to get vitamins from the fruits in our bodies, and we would die if we didn't have water!
Therefore, the answer is food, water, oil, gas, and wood.
