What type of organism directly interferes with human activities or natural resources?

The term "aquatic pest" refers to organisms that have a negative impact on human activities or interfere with the management and preservation of natural resources. These pests can include invasive species, harmful algae, or disease-carrying organisms that disrupt ecosystems, affect aquaculture, or contaminate water sources. Their presence can lead to significant economic losses and ecological damage, making them a focus for pest management strategies.

Beneficial organisms typically play a positive role in the environment, such as pollinators or organisms that maintain the health of ecosystems. Native wildlife encompasses species that are indigenous to a particular area and are a natural part of that ecosystem, usually without causing disruption. Natural resource managers are professionals focused on the stewardship and sustainable management of resources, rather than being organisms themselves.

Thus, the correct identification of aquatic pests as the organisms that directly interfere with human activities or natural resources highlights the importance of understanding and managing these species to protect both human interests and ecosystem balance.
