Answer

1. **C. the number of different species in an area** Diversity and biodiversity both refer to the variety of life, specifically the number of different species present.<br /><br />2. **A. species at risk** Species at risk are those facing a high probability of extinction in the wild.<br /><br />3. **D. nitrogen** Nitrogen is a crucial nutrient for plant growth and is a key component of synthetic fertilizers.<br /><br />4. **A. pesticides and synthetic fertilizer** Pesticides control pests that damage crops, while synthetic fertilizers provide nutrients for plant growth, both contributing to increased food production.<br /><br />5. **C. biological magnification** This term describes the increasing concentration of substances like DDT as they move up the food chain.<br />
