1. Describe three different types of relationships in a community between two different
populations of organism. SC.7.L.17.2
2. Compare and contrast the feeding habits of carnivores, omnivores, and producers.
SC.7.L.17.1
3. Predict what might happen to a population of snakes if their main food source, mice, were to
lose access to food and water? SC.7.L.17.1-SC.7.L.17.3
4. Describe. Choose a limiting factor in your local ecosystem and describe how it restricts the
population of a plant species in your environment. SC.7.L.17.3

The diagram below represents a marine food web and a process that can harm the human population. each circle represents an organism and the smaller dots inside them represent a toxic substance. what is being represented and how does it harm the population? the diagram represents biological half-life, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents biomagnification, in which toxins build up in organisms higher up on the food chain, and this can negatively impact humans who consume the organisms and the toxic substance. the diagram represents the process by which different organisms prey upon each other; this can impact the human population by reducing the number of organisms that do not contain the toxin. the diagram represents the way that toxins are metabolized by living organisms, with those at greater trophic levels able to metabolize more efficiently than those at lower levels. this means that those at higher tropic levels are safer for humans to consume compared to the organisms at lower trophic levels.

Now it's your turn to investigate human impact around the world. grab your virtual lab coat and put on your environmental science hat. you will be taking a trip around the globe to explore three locations. at each location, you will investigate the cause and effect relationships of deforestation, desertification, and urbanization. you will also gather evidence of how these factors have impacted the environment over time

Which characteristics are typical of a human population in the postindustrial stage?
