BIOL 1902 Lecture Notes - Lecture 3: Eating Animals, Anglerfish, Flesh Fly
Document Summary
Plant and animals face different challenges when it comes to acquiring food: plants create their own food. Animals can (1) eat plants, or (2) eat other animals. Some animals go and find their own food, while other animals have food delivered to them. Analogouse structures: structures that have the same function as another structure on a different animal but arises from a different part of the body. Every part of a plant is a food source for animals; leaves, stems, fruit, sap, etc. Plant tissue is very hard to break down and eat because of the structures of the cell walls. Detritivore: an animal that eats dead plant materials. Scavanging: animals that eat animals that are already dead (1) filter feeders have their own food delivered to them. These include: clams, baby black flies, ducks, swans, Labral brushes: hair like structures on the mouths of baby black flies that gather material in the water and pull them into their mouths.
