Biology HS/Science Unit: 02 Lesson: 01 Symbiotic Relationships Chart There are four types of symbiosis you will explore today. Commensalism is a symbiotic relationship in which one organism benefits and the other organism neither benefits nor is harmed. Mutualism is a symbiotic relationship in which both organisms benefit. Symbiosis is an ecological interaction between two organisms. Parasitism is a symbiotic relationship in which one organism benefits and the other organism is harmed. Predation is a symbiotic relationship in which one organism preys on (and eats) another organism. Objective: Given a description of the relationship between two organisms, determine if their relationship is commensalism, predation, mutualism or parasitism. Procedure: 1. Draw two cards from each beaker labeled #1 #4. 2. Read the relationship described on each card. Determine what type of relationship this is and record the name of the organisms in the correct place on the chart. Add a few brief notes to help you remember your reasoning for your decisions. 3. When your chart is complete, use tape to post your cards onto the correct pieces of butcher paper posted around the classroom.

Parasitism Cards: Cuckoo and Warbler Deer and Tick A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young Ticks feed on dee r blood, causing irritation to the deer and will displace the warbler’s young, and the warbler will raise the potentially giving it various diseases such as Lyme disease. cuckoo’s young. Lice and Humans Mistletoe and Oak Tree Lice attach to human hair and enjoy the warmth given off by the Mistletoe extracts water and nutrients from the oak tree, causing human. They eat tiny amounts of human blood, causing the harm to the oak tree. human to have little r ed bumps that are quite itchy. They may also transmit disease to the human. ©2012, TESCCC 04/10/13 page 3 of 8 Biology HS/Science Unit: 02 Lesson: 01 Fleas and Cat Bird Mites and Humans Bird mites might happen upon a human when trying to find a new Fleas live on the cat’s body and eat its blood. They cause irritation bird to feast on. Instead, it eats the blood of the human, causing to the cat and may transmit disease to the cat. the human to develop irritating, itchy bumps. Tapeworm and Dog Bed Bugs and Human The tapeworm enters the dog when the dog eats feces containing tapeworm larvae. The tapeworm attaches to the dog’s stomach Bed bugs will bite and feed off a human up to 500 times in one and fee ds off of the dog’s nutrients. This often causes harm to the night. This causes small red bumps and itchiness to the human. dog. Black Wasp and Aphids Braconid Wasp and Tomato Hornworm Larva The braconid wasp deposits its eggs inside the tomato hornworm Bla ck wasps plant eggs in aphids. The larvae eat the aphids from larva. When the eggs hatch, the wasps eat their way out which the inside. kills the hornworm. Mosquitoes and Human Downy Mildew on Vegetable Plants Mosquitoes find a hum an and feast upon their blood. This causes The downy mildew fungus invades a host plant and feeds off it. a small reaction on the human’s skin, r esulting in a red, itchy This often causes discoloration or stunted growth in the plant. bump. In addition, mosquitoes can pass along disease to their human host. ©2012, TESCCC 04/10/13 page 4 of 8 Biology HS/Science Unit: 02 Lesson: 01 Commensalism Cards: Maribou Stork and Bees Hermit Crabs and Snails The stork uses its saw -like bill to cut up the dead animals it eats. Hermit crabs live in shells made and then abandoned by snails. As a result, the dead animal carcass is accessible to bees for food and egg-laying. Bison and Cowbird Remora Fish and Shark Remoras attac h themselves to a shark’s body. They then travel When bison walk through fields it causes insects to become more with the shark and f eed on the leftover food scraps from the active. The cowbrds are able to see the insects and eat them. shark’s meals. Human Gut Bacteria and Humans Whales and Barnacles Certain bacteria live within the digestive system of humans and Barnacles create home sites by attaching themselves to whales. feed on various things within the human. This is not detrimental to the human. ©2012, TESCCC 04/10/13 page 5 of 8 Biology HS/Science Unit: 02 Lesson: 01 Clownfish and Sea Anemone Cattle Egret and Cattle or Horses The clownfish lives within the tentacles of the sea anemone. This The cattle egret follows cattle or horses and preys on the insects provides protection to the clownfish , and the clownfish also feeds the animals stir up as they graze. on the food scraps of the sea anemone. Golden Jackals and Tigers Birds and Army Ants If a golden jackal is expelled from its pack, it may attach itself to a Army ants raid forest floors and when they do it causes various particular tiger, trailing it at a safe distance and then feeding on the flying insects to stir. Some birds will follow the army ants and then tiger’s kills. eat the instects that they stir up. Orchids and Trees Mosses and Trees Mosses are a plant that is able to grow on the trunks or branches Orchids are a flower that grow along the trunks o r branches of of trees. This allows the mosses to receive light as well as trees. This allows the orchid to receive light as well as nut rients nutrient s that run down the trees. The trees are unharmed by the that run down the trees. The trees are not harmed by the orchids. mosses.

Mutualism Cards Ostrich and Gazelle Yucca Plant and Yucca Moth Ostriches and gazelles gather food in areas close to each other. Yucca flowers are pollinated by yucca moths. The moths lay their They have different visual abilities so th ey are able to help warn eggs in the flowers where the larvae hatch and eat some of the each other when predators are nearby. They help each other developing seeds. avoid danger. Wrasse Fish and Black Sea Bass Oxpecker and Rhinoceros Oxpeckers feed on th e ticks found on a rhinoceros. In addition, if Wrasse fish feed on the parasites found on the black sea bass’s they sense danger, the oxpecker will fly up and scre am out as a body. warning to the rhinoceros.
