Scenario 2
A black widow spider is capable of producing hundreds of offspring at one time. Black Widow spiders catch their
prey using webs. The strength of the web varies by the spider that spins it. The stronger the web, the more
likely it is that the prey will not be able to escape the web. Therefore, spiders that have the ability to spin
stronger webs are more likely to catch prey, which increases their odds of surviving to reproduce.

Ameadow ecosystem includes many species of grasses and small shrubs, several herbivores, and a few carnivores. a fungus colonizes the meadow and kills most of its vegetation. what is most likely to happen to the populations of herbivores and carnivores in the ecosystem? a. the populations of herbivores and carnivores will increase because there will be less competition for chemical energy. b. the populations of herbivores and carnivores will remain stable because the fungus cannot infect these organisms. c. the populations of herbivores will decrease because of vegetation loss, but the population of carnivores will remain stable. d. the populations of herbivores and carnivores will decline because less chemical energy will be stored in the ecosystem.
