A food chain can usually sustain no more than six energy transfers before all the energy is used up. And so less energy is transferred at each level of the food chain so the biomass gets smaller.
The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.
A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.
Generally, air can be trapped in a balloon by sealing its neck tightly.
Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.
A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.
In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.
