Study Notes
Feeding Mechanisms and Digestive Systems
-
Filter Feeders: Filter nutrients from water; examples include whales and sponges. They consume small organisms.
-
Cnidarians: Soft-bodied, stinging animals; examples include corals, sea anemones, and jellyfish.
-
Ruminants: Herbivorous animals with four-chambered stomachs (e.g., cows, sheep, deer). Their stomachs are adapted for fermenting plant materials using microbes.
-
Detritivores: Feed on decomposing plant and animal matter; examples include earthworms, fungi, and insects.
-
Omnivores: Consume both plants and meat; examples include humans, dogs, and birds.
-
Herbivores: Feed only on plants; examples include cows, rabbits, and snails. Their bodies have unique features for plant-based diets.
-
Carnivores: Feed only on meat; examples include lions, tigers, wolves. Their bodies feature adaptations for tearing and chewing meat.
Mouthpart Differences
-
Herbivores: Have flat molars and incisors, small canines, and elongated jaws to chew plant matter. Incisors act like “nail clippers” to chop off leaves.
-
Carnivores: Have sharp canines for grabbing prey, sharp molars and incisors for tearing flesh, and strong jaws. Their tongues are rough for gripping and manipulating food.
Microbiome Benefits
- Microbiome bacteria are essential for digestion. They prevent illnesses like diarrhea and digestive problems, and support immunity.
Digestive Systems of Different Organisms
-
Humans: Digestion begins in the mouth and continues in the stomach and intestines. Enzymes break down carbohydrates, proteins, and fats.
-
Ruminants: One-way digestive tract with a multi-chambered stomach (rumen) to ferment plant materials with microbes. They have a crop to temporarily store food and a gizzard to grind food.
-
Birds: Use a crop to store food temporarily and a gizzard to grind food using small rocks.
-
Sponges: Filter feed, trapping particles as water passes through their pores.
-
Cnidarians: Use specialized stinging cells to capture prey.
