The answer is sponges.
Animals with the radial symmetry of the body have<span> body parts that seem to extend from a central point, just like spokes in a bicycle wheel.
Through the process of elimination:
Sponges have radial symmetry.
Flatworms have bilateral symmetry.
Crayfish have bilateral symmetry.
Therefore, among all choices, only sponges have </span>body parts that seem to extend from a central point, just like spokes in a bicycle wheel. <span>

rusting of iron is a chemical change because it is two substances reacting together to make a new substance. When iron rusts, iron molecules react with oxygen molecules to make a compound called iron oxide. Rusting would only be a physical change if iron molecules remained pure iron throughout the process.

It is supposed to flow through so heterotrophs(like humans etc) can gain energy from plants(autotrophs) which other animals gain energy from them eating each other which follows the food chain. Which keeps the food chain and life in order, by giving energy for work and life to sustain.
x or y because both can cause it
