4. Which statement classifies dogs as consumers?

A. Dogs have dog houses,

B. Dogs eat green beans and steak.

C. Dogs can sit on command.

D. Dogs love humans which benefits the ecosystem.

Dogs are classified as consumers in ecological terms because they rely on other organisms for food. When we say that dogs eat green beans and steak (option B), we highlight their role in the food chain, as they do not produce their own food but instead consume plants and animals to obtain energy and nutrients. This positions them in the consumer category alongside other animals that depend on various food sources.

In the grand scheme of ecosystems, understanding animal roles like that of dogs gives us insights into food webs and biodiversity. Just like humans, dogs impact their environment through their dietary habits. Knowing that dogs are both domestic companions and biological consumers can help us think about how to balance pet care with environmental responsibilities, such as choosing sustainable pet food or ensuring that our furry friends have a healthy diet that doesn’t harm ecosystems.
