PPT-Biodiversity, Species Interactions, and Population Control

Chapter 5 Key Concepts Species interactions Responses to changes in environmental conditions Factors determining number of species in a community Species Diversity and Ecological Stability. What is Biodiversity?. All living things in a food web are connected.. If the numbers of one species are affected it affects the numbers of all other species in the food web.. If the numbers of baboons decreased then this would affect every other living things in the food web.. AP Environmental Science. Mr. Grant. Lesson . 38. Objectives:.

Spoolman. , 2010). Figure 5.1. An endangered southern sea otter in Monterey Bay, California (USA), uses a stone to crack the shell of a clam (insert). It lives in a giant kelp bed near San Clemente Island, California (background). Scientific studies indicate that the otters act as a keystone species in a kelp forest system by helping to control the populations of sea urchins and other kelp-eating species.. Saving the Siberian Tiger. Siberian tigers are one of five remaining tiger subspecies.. In the early 20th century, hunting and habitat loss reduced the wild population to just 20–30 animals.. Conservation efforts have helped the wild population rebound to 450–500 today.. I. Biotic and . Abiotic. Factors. A.
