Human Impacts on Ecosystems

Which of the following is a way humans are responsible for habitat destruction?

• Deforestation

• Planting a garden

• Replacing trees that have been cut down

• Restoring a wetland

Toxins accumulate in the tissues of organisms as they pass through a food chain/web.

• eutrophication
• biomagnification
• ecological succession
• symbiosis 

Increased industrialization will most likely

• decrease available habitats 
• increase environmental carrying capacity 
• increase the stability of ecosystems 
• decrease global warming
