Give reasons for each of the following: 1. Why are plants important for heterotrophic nutritio 2. Why is digestion necessary in animals? 3. Why do we need to take care of teeth? 4. Why do animals ruminate?
Answers
Answer:
3- we need to take care of teeth because it helps prevent cavities and gum disease
Answer:
1) Heterotrophic nutrition is a mode of nutrition in which organisms depend upon other organisms for food to survive. They can't make their own food like Green plants. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight.
2) All animals need to break down food molecules into smaller pieces so they can circulate them around their bodies to all their cells. ... Digestion occurs when the animal's body gets busy breaking down the food.
3) Taking care of your teeth helps prevent cavities and gum disease. Brushing and flossing properly can prevent plaque (pronounced: plak), a clear film of bacteria that sticks to your teeth. After you eat, the bacteria break down sugar on your teeth into acids that eat away tooth enamel, causing holes called cavities.
4) The rumination process allows these animals to eat forages and other high fiber feeds that are not be able to be eaten by humans and other non-ruminant animals.As partially digested feed passes through the omasum, water is absorbed, reducing the volume of material that arrives in the abomasum.
