Producers make their own food, while primary consumers eat producers.

Producers eat primary consumers, while primary consumers make their own food.

Producers and primary consumers both make their own food.

Producers and primary consumers both eat other organisms.

Secondary consumers are carnivores (eat meat), while tertiary consumers are the second level consumers that eat meat eaters, like secondary consumers.

Secondary consumers eat plants, while tertiary consumers eat animals.

Secondary consumers are at the top of the food chain, while tertiary consumers are not.

Secondary consumers and tertiary consumers eat the same type of food.

A food CHAIN shows the link from one organism to the next while a food WEB is more complex. It shows how several food chains are connected within an ecosystem.

A food chain is a complex network of many interconnected food chains and feeding relationships, while a food web is a linear sequence of organisms where nutrients and energy pass as one organism eats another.

A food chain and a food web are the same, with no differences.

A food chain is a diagram showing the flow of energy between organisms, while a food web is a list of organisms in an ecosystem.

Matter and energy flow in a linear path from producers to consumers.

Matter is recycled in the ecosystem, while energy flows in a linear path.

Both matter and energy are recycled in the ecosystem.

Energy is recycled in the ecosystem, while matter flows in a linear path.
