I/GCSE Biology - Surviving the presence of others

Surviving the presence of others

· igcse biology,gcse biology,surviving,animal,competition

In this blog post, we will talk about the special adaptations and competition of organisms in I/GCSE Biology. Let's get started! 🐒

Keeping others away

  • For organism to grow, mature, produce offspring = avoid being eaten by other microorganisms
  • It's commonly asked in I/GCSE Biology!

Special adaptations – avoid being eaten

  • Physical deterrents e.g. cacti🌵 = thick spines
  • Chemical deterrents e.g. ragwort (plant) = poisons (taste bad or kill)
  • Advertise poisons with bright colours
  • Camouflage – hide from predators (colours + patterns on body = difficult to see)
Can you see the animal in the following picture? 😆

Competing for resources

In I/GCSE Biology, you should be familiar with the competition among organisms!

Reasons for competition among organisms:

  1. Enough resources for all organisms  ➡️  rare
  2. Limited resources ➡️ organisms compete
  • most successful ➡️ grow better + more offspring produced

Please remember to study competition of plants and animals separately in I/GCSE Biology XD!

Plants

  • compete for water, light, nutrients (if grown close together)
  1. Bluebells ➡️  grow, flower + seed before tree fully grown (no sun blocked)

Animals

  • compete for food
  1. Leopards ➡️ takes kill to trees (keeps other animals away from stealing their food)
  • compete for mates
  1. Male peacocks display feathers when females around – best display ➡️ mate with the most females
  2. Birds 🐦 ➡️ territories when breeding
  3. Robins ➡️ large territory to feed young
  4. Birds 🐦 away from nest site e.g. penguins / gannets ➡️ small nesting territory (out of pecking distance of other adults)
