Energy expenditure in resource management

Suppose a tree squirrel living in the conifer forests near La Grande eats seeds that it extracts from pine cones and fungi that it finds on the forest floor. Also, suppose that currently it takes an average of 2 minutes to find a cone and 4 minutes to find a fungus. It takes 10 minutes to break open the cone and eat the seeds an

Think about gazelles, zebras, antelopes, and other large hooved animals living in herds on the plans of Africa where there are a variety of species of large mammation predators like cheetahs, lions, leopards, hunting dogs, etc. Visualize that you are a member of one of those prey species. Explain about the antipredator mechanism

Taxonomic Category and Dichotomous Key

In the animal kingdom, you can place animals in categories based on certain differences in the characteristics that each possesses. If you know what critical traits to look for, it is possible to separate any animal into its proper taxonomic category. Use this dichotomous key to help determine the taxonomic category to which a s
