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.
Keywords:

Slide 5 - Diapositive
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.
Slide 6 - Diapositive
Competition:
Organisms can compete for space, food, partners, light, etc. (biotic and abiotic factors).
Slide 7 - Diapositive
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
