In the food chain 'grass is eaten by a grasshopper, which is eaten by a frog, which is eaten by a snake,' what is the first link?
AThe snake, because it is the strongest
BThe grasshopper, because it is the smallest
CThe grass, because it makes its own food from sunlight
DThe frog, because it is in the middle
Every food chain starts with a plant or other organism that makes its own food. The grass uses sunlight to make energy, the grasshopper eats the grass, the frog eats the grasshopper, and the snake eats the frog. Energy flows from the sun through each link in the chain.
Question 2 True / False
Animals at the top of a food chain do not depend on plants.
TTrue
FFalse
Answer: False
Every animal depends on plants, even if it does not eat them directly. A snake eats a frog, which ate a grasshopper, which ate grass. Without the grass, the grasshopper would starve, then the frog would starve, and then the snake would starve. The whole chain depends on plants at the bottom.
Question 3 Short Answer
What would happen if all the rabbits disappeared from a food chain of grass, rabbit, fox?
Think about your answer, then reveal below.
Model answer: The foxes would lose their food source and might starve or have to find other food. The grass might grow too much because nothing is eating it.
Every part of a food chain is connected. Remove one link, and the links above and below are affected. Without rabbits, foxes lose food. Without rabbits eating it, grass overgrows. This shows why balance in nature matters — every living thing plays a role.
