SYMBIOTIC RELATIONSHIPS

This article explores the four types of symbiotic relationships - mutualism, parasitism, commensalism, and competition. It provides examples and explains how these relationships can be beneficial or harmful. Symbiotic relationships develop over time through evolution between two species.

  1. SYMBIOTIC RELATIONSHIPS SYMBIOSIS - A RELATIONSHIP BETWEEN TWO ORGANISMS WHICH LIVE CLOSELY TOGETHER. THESE ORGANISMS MAY SHARE A HABITAT OR ENVIRONMENTAL FACTOR

  2. 4 TYPES OF SYMBIOSIS MUTUALISM + + PARASITISM + - COMMENSALISM + 0 COMPETITION - -

  3. MUTUALISM + + • BOTH ORGANISMS BENEFIT Hermit Crab & Anemones https://www.youtube.com/watch?v=dYFALyP2e7U Hermit Crab - gets protection Anemones – gets extra food

  4. MUTUALISM + + • BOTH ORGANISMS BENEFIT Giraffe & Oxpecker https://www.youtube.com/watch?v=9r9PTqbHVvQ Giraffe gets its parasites removed & Oxpecker gets food

  5. MUTUALISM + + • BOTH ORGANISMS BENEFIT Ants and Acacia Tree https://www.youtube.com/watch?v=Xm2qdxVVRm4 Ants have a home & Acacia tree gets protected

  6. PARASITISM+ - • PARASITE BENEFITS + HOST LOSES - Mosquitoes or Ticks and a Host https://www.youtube.com/watch?v=REkQ66zQRWg Mosquito or Ticks get a meal of blood and the Host loses blood

  7. PARASITISM+ - • PARASITE BENEFITS + HOST LOSES - Intestinal Worm and a Host https://www.youtube.com/watch?v=MofTs8yLzeM Worm eats host’s digested food and the host loses nutrients

  8. PARASITISM+ - • PARASITE BENEFITS + HOST LOSES - Parasitic plants & a Host plants https://www.youtube.com/watch?v=SwfhYYnmLYM Parasitic plants take nutrients from other plants. The host plant gets weak and may die.

  9. COMMENSALISM+ 0 • ONE BENEFITS THE OTHER HAS NO EFFECT Remora on a shark https://www.youtube.com/watch?v=yzDWWzDenZQ Remora gets extra food from the shark The shark gets nothing in return

  10. COMMENSALISM+ 0 • ONE BENEFITS THE OTHER HAS NO EFFECT Epiphyte on a tree branches https://www.youtube.com/watch?v=RYi6NjtJOas Epiphyte plant grows on tree branches Host tree is unaffected

  11. COMMENSALISM+ 0 • ONE BENEFITS THE OTHER HAS NO EFFECT Mites on human’s skin https://www.youtube.com/watch?v=Tbr3PMNrfbw Mites feed on human skin & oils Most humans have no effect

  12. COMPETITION- - • BOTH ORGANISMS LOSE Predators Predators have limited food to catch and use a lot of energy to catch and protect their prey from other predators https://www.youtube.com/watch?v=_t1cHIgYFWo

  13. COMPETITION- - BOTH ORGANISMS LOSE Cactus and Desert Plants https://www.youtube.com/watch?v=gw9zJM5jaSI Cactus and other desert plants share limited water and therefore grow slowly.

  14. COMPETITION- - BOTH ORGANISMS LOSE Grazing Animals In Africa Zebra & Wildebeest have limited food and water supplies and must search long distances to get enough https://www.youtube.com/watch?v=thJwM7oEBSo

  15. IN SUMMARY: THERE ARE FOUR TYPES OF SYMBIOTIC RELATIONSHIPS: MUTUALISM, PARASITISM, COMMENSALISM, COMPETITION THESE RELATIONSHIPS CAN BE BENEFICIAL OR HARMFUL SYMBIOTIC RELATIONSHIPS DEVELOP OVER TIME THROUGH EVOLUTION BETWEEN TWO SPECIES.
