A. Definition & Why?

Nutrition = bioenergetics or energy required for LifeStrategies are based on metabolic rate and can

be divided into endothermic and ectothermic.

Metabolic rate == making and using ATP

B. Metabolism Overview

1. Basal Metabolic Rate vs. Standard Metabolic Rate

2. Energy Budgets based on size, environment, behavior, and energy strategy

Size vs. Energy Expenditures

3. Regulation of intake is controlled by need?
