Lesson 4 - adaptation and competition  

Learning goals:

•  I can explain what adaptations are.
  
• I know what types of adaptations are possible.
  
• I can name various examples of various types of adaptations.
• I can identify & explain these adaptations in new contexts
• I know what competition is and can explain various types/examples of this.
  
• I know what a predator-prey is and can interpret the graphs.
• I can identify & explain various types of symbiosis.

Types of adaptation:

Structural Adaptation: These are physical features or body parts that help an animal survive.

Example:

A giraffe’s long neck for reaching high leaves.

Camouflage, like a chameleon changing color to blend into surroundings.

Physiological Adaptation: This involves internal body processes or functions that improve survival.

Example:

A snake producing venom to catch prey.

Desert animals conserving water by producing concentrated urine.

Behavioural Adaptation: This refers to actions or behaviors animals have developed to survive in their environment.

Example:

Birds migrating to warmer climates during winter.

Nocturnal animals being active at night to avoid predators or heat.

Competition:

Organisms can compete for space, food, partners, light, etc. (biotic and abiotic factors).

relationships/symbiosis:

Mutualism: A type of symbiosis where both species benefit from the relationship.

Example: Bees and flowers – Bees get nectar from flowers (food), and in return, they help pollinate the flowers.

Commensalism: A relationship where one species benefits, and the other is neither helped nor harmed.

Example: Barnacles on whales – Barnacles get a place to live and access to food as the whale moves, while the whale is unaffected.

Parasitism: A relationship where one organism (the parasite) benefits at the expense of the other (the host).

Example: Ticks on dogs – Ticks feed on the dog’s blood, potentially causing harm, while the dog gets no benefit
