Food Pyramids

The relationship between organisms, showing who eats whom, or a food chain is shown in a pyramid shape, called a food pyramid.  The length of the blocks above is proportional to the size and number (biomass) of organisms in that group.


There are so many plants and insects on earth because they are the basic food for the rest of the animals and plants.

The producers are eaten or used by the consumers.

Remember the living part of the ecosystem is dependent on the non-living part.
