Evolution, Ecology & Sustainability

Lesson 3 - the study of ecosystems

P. 314-321 

Keywords:

• ecology
• ecosystem
• habitat
• community
• population
• biosphere
• biotic factors
• abiotic factors
• ecological tolerance

Learning goals:

• I know how organisms interact with each other.
• I know what a ecosystem consists of.
• I know the difference between biotic and abiotic factors
• I can explain how biotic and abiotic factors influence population size
• I know the different organisation levels of biology
• 
  
• 
  

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 can identify & explain various types of symbiosis.

Keywords:

•  Adaptations
  
• Structural Adaptation
  
• Physiological Adaptation
  
• Behavioural Adaptation
  
• Competition
  
• Resources
  
• Territory
• 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

assignment :

Go to your assignment from lesson 3 on classroom:

1. Give an example of each type of adaptation for your favorite animal

2. Give an example of each type of symbiosis your favorite animal has. 

3. Give an explanation to the temperature tolerance. (why is the animal not capable of survivibg at higher and lower temperature)
