The specific trophic level of a human depends on their diet. For example, a person who eats only plants is a primary consumer. A person who eats both plants and animals is a secondary consumer. A person who eats other animals that eat other animals is a tertiary consumer. And so on.
Humans also have an impact on the food web through their activities. For example, humans hunt and fish for food, which can reduce the populations of prey species. Humans also clear land for agriculture, which can destroy habitats and displace animals. Additionally, human activities such as pollution and climate change can have negative effects on the entire food web.
