Akoranga 11 Mahi Tuatahi

  1. Describe the role of the raccoon in the food web
  2. What are some resources that the raccoon will compete with other raccoons for?
  3. Discuss: Why can some racoons compete for resources better than other racoons?

Adaptations

  • An attribute of an organism that helps them compete so they can survive and reproduce
  • They come in three categories: structural/physical, physiological, behavioural

Structural/Physical

Physical features of an organism like the bill on a bird or the fur on a bear.

  • Humans evolved standing upright on two feet (bipedalism) which allowed us to do long distance running to catch food & migrate

Physiological

Metabolic or physiologic adjustment within the cell, or tissues, of an organism. Internal chemical processes.

  • The human metabolic system (conversion of sugar into energy/heat) increases when we are cold in order to keep us warmer

Behavioural

The things organisms do to survive. For example, bird calls and migration.

  • Humans learned to use tools to create warm clothes/indoor environments so that we can survive cold areas

Te Whāinga Ako

  1. Relate an organisms adaptations back to its niche.

“Fitness”

  • Not cardiovascular fitness, but evolutionary fitness
  • This means: how well you are adapted to your environment
  • How well you can compete for resources, survive and reproduce!
  • Better adaptations leads to greater ability to compete and reproduce!
