Parasitism

Mutualism

Symbios

The long-term living together of organisms of different species

Influences from the non-living environment

The guest benefits and the host is neither helped nor harmed

The struggle for food, a mate or a safe place between individuals

Overpopulation


Environmental problems










  • Depletion

  • Pollution

  • Climate change

raw materials for example

machines, devices, houses

Fossil fuels

gas, petrol, diesel

depletion

pollution


  • Air

  • Water

  • Soil

nitrogen -stikstof


  • Fertiliser and traffic → nitrogen in soil/water/air

  • → lots of nettles and grasses, little biodiversity

  • Air pollution = smog/fine particulates (fijnstof) 








soil pollution










toxic waste → roots → food chains










water pollution


Wastewater (agriculture, industry, households, ships)

→ toxic substances in the water


Harmful to organisms + humans!









worksheet



Versterkt broeikaseffect


  • Broeikasgassen (zoals CO₂) houden warmte vast 


  • Door meer CO₂-uitstoot is het broeikaseffect sterker geworden.


  • Gevolg: opwarming van de aarde

gevolgen klimaatverandering

  • Zeespiegel stijgt → laaggelegen gebieden (zoals Nederland) kunnen overstromen.

  • Meer blauwalg in water → giftig, zwemmen soms verboden.

  • Meer droogte en verzilting → landbouw moeilijker.

  • Sommige mensen moeten verhuizen door stijgend water of voedseltekorten.
