This is when you lose weight, gain weight, then lose weight, then gain more weight than you had before!! It can go on for a very long time. Many obese people suffer from this.
Answer:
D, acting based on instinct
Explanation:
By acting based on instinct you are not giving enough time or thought towards your decision. You're acting too quickly to fully understand your decision making process or the decision itself.
Start with your producers, or plants (grasses, flowers, etc.). Then your 1st level consumers (herbivores), like grasshoppers, mice, etc. Then your second level producers (carnivores and omnivores) that eat the herbivores (like birds). And keep going, knowing each of the levels get eaten by each other. 10% of energy is transferred in each level. An example might be...
Grass > Mice > Hawk > Vulture
