2 Problem Area 5 Game Animals Management

3 Lesson 2 Identifying Foods & Environmental Requirements

4 Nutritional Label Lets discuss the nutrients that we consume from this food. –Fat –Carbohydrates –Proteins –Vitamins –Minerals What nutrients do animals need?

5 Objectives Describe essential nutrients needed by animals. Identify food sources of plant origin. Identify environmental factors that affect the food supply. Describe ways that humans can supplement the natural food supply.

6 Terms Drought Energy nutrients Flowers Fruit Leaves Proteins Minerals Nematodes Nuts Pods Roots Vitamins Water

7 Essential Nutrients What is the main reason that animals need these essential nutrients? –To sustain life

8 Essential Nutrients Nutrient requirements vary during the life cycle. –Mature animals need nutrients to provide for their activity, maintenance of their body, and reproduction. –Lactating females have increased need for nutrients.

9 What are the essential nutrients needed by animals? Energy nutrients Proteins Minerals Vitamins Water

10 Energy Nutrients Carbohydrates and fats –Energy is needed for the animal to maintain its body and to provide for its activities. –Sugars, starches, and oils provide energy nutrients.

11 Proteins Necessary for animal growth, maintenance, and reproduction. More protein is needed during periods of active growth and during lactation. Some animals, such as carnivores, get protein from eating other animals. Plant eating animals can get protein from eating seeds and young, tender vegetation.

12 Minerals Needed for growth, reproduction, and other life functions. Very important for bones, hooves, teeth, horns, and other similar body parts. Minerals are available in the food and water that animals consume.

13 Vitamins Regulate body processes and can be found in the foods animals eat. Vitamins A, D, E, K, and B complex are very important for animal health.

14 Water Nutrient that is very important for animal health. Animal consumption of water varies by species and location. As much as 40 percent of an animals body is water. A good source of clean, non-polluted water is essential for animal health.

15 Essential Animal Nutrients

16 What are animal food sources that come from plants? Plants provide many sources of food for animals. Different animals utilize different parts of plants. –Leaves –Flowers –Fruit –Nuts –Seeds –Twigs & bark –Roots

17 Plant Parts Leaves – green, vegetative part of the plant. –Ruminant animals, such as deer and bison, utilize them extensively. Flowers – provide nectar for various animals. –Ex. bees, butterflies, hummingbirds

18 Plant Parts Fruit – contains seeds and other edible parts. –Grows on plants after it has flowered. –Berries are one example of fruit.

19 Plant Parts Nuts – grow on trees and contain the seeds from the tree, usually have a hard outer shell. –Acorns and pecans are examples. Pods – seed from plants that do not produce fruit or nuts.

20 Plant Parts Twigs & Bark – Some insects burrow into the bark of some trees and sometimes deer will eat the bark and twigs off trees. Roots – underground portion of the plant. –Rodents and nematodes (small worms) for example.

21 What environmental factors can affect the food supply for animals? Weather Pests Fire

22 Weather Related Problems Drought – prolonged period without enough rain. –Mild droughts can cause a decrease in production of plant material. –In severe cases, large amounts of plant material can be killed, thus drastically affecting the food supply.

23 Weather Related Problems Storms can remove vegetation, fruits, nuts, and seeds from plants. –Severe storms, such as tornados and hurricanes can blow down trees and other plant life. –Ice storms can cause severe plant damage.

24 Weather Related Problems Floods can smother plant life and kill it by preventing respiration and photosynthesis. Untimely freezes can kill vegetation prematurely, or cause early season fruits to drop to the ground.

25 Pests Pest outbreaks can severely affect the food production of some plant species. These can include insects and disease. In some cases, insects and diseases can destroy whole plant communities.

26 Fire Each year, thousands of acres of forest are destroyed by fire. Sometimes these fires are caused naturally by lightening, while other fires are caused by human carelessness.

27 What can humans do to supplement the natural food supply? Leaving strips of untilled land around the edges of fields. These strips can provide both food and cover for wildlife. Planting food producing trees, shrubs, and other plants.

28 What can humans do to supplement the natural food supply? When harvesting trees out of a forest, leaving food producing trees. Providing corn and other feeds to wildlife. Providing fertilizers to ponds to produce aquatic plants for fish to consume.

29 Review / Summary What are the essential nutrients needed by animals? What are animal food sources that come from plants? What environmental factors can affect the food supply for animals? What can humans do to supplement the natural food supply?
