Concept explainers

Nutrition and diet

We are involved in several daily activities. These actions need a significant quantity of energy. The food we eat provides this energy. Food is necessary for development, repair, and other living activities since it supplies energy. All of these are part of the living practice known as nutrition. Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists employ concepts from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body. Nutrition also looks at how people can use their diet to reduce their risk of disease, as well as what happens when they ingest too much or too little of a nutrient and how allergies emerge.

1. Study the 3 diagrams showing hypothetical moose populations with 2 different dispersion pattern.Describe how the moose are dispersed in each diagram2. The shaded portions of the diagrams show the transects that were used to sample each population.What proportion of the total study area (defined by the box) was sampled in each of the three cases?3. Count the number of moose encountered within the transect areas for each case. Do not count the total number of moose in any of the diagrams. From these counts, estimate the size of the 3 moose populations. 4. The actual numbers of moose in the 3 populations are 60, 133 & 133, respectively. How close were your estimates?
