In a complex ecosystem with a variety of plants and animals, which of the following is the best visual tool to display the flow of energy?
a- photographs of plants growing and animals eating
b- lists showing all of the food sources for each animal in the ecosystem
c- a table categorizing the animals as plant-eating or meat-eating
d- a model of the food chain in the ecosystem
d- a model of the food chain in the ecosystem is the best visual tool to display the flow of energy in a complex ecosystem.
