An acorn is eaten by a squirrel, which is by an owl what model best describes this simple relationship, and how does it show energy flow

You can draw a triangle with three different areas. The first area (lowest floor) should be the acorn. Next should be the squirrel because it ate it. Lastly, the third floor should be owl because it ate the squirrel. By everything you move up you need to add the 10% rule.

Ithink its false. hope this : )
