Most years, severe cold temperatures destroy a large number of grasshopper eggs. During one particular year, however, a mild winter allowed the grasshopper population to increase. This resulted in a well-fed frog and toad population as well as plenty of food for insectivorous snakes and birds. Unfortunately, the increased number of grasshoppers caused a higher percentage of crop damage due to insects. Which of the following best summarizes the food chain described in the paragraph above? crop --> grasshoppers --> snakes or birds crop --> grasshoppers --> snakes --> birds crop --> birds --> snakes crop --> grasshoppers --> toads --> birds

Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
