Homework 

I can... 

• explain how organisms interact through mutualism, commensalism, and parasitism.
• describe how mutualism, commensalism, and parasitism are similar and different.
• give examples of interactions between organisms through mutualism, commensalism, and parasitism.

keyterms: interdependent - symbiosis - mutualism - commensalism - parasitism 

Raise your hand if someone else made dinner for you last night

this means you were interdependent on someone else 

Plants, fungi, bacteria and animals also use or rely on others to benefit themselves.
For example, the impollination of an apple flower depends on honey bees. Give another example

Give an example of commensalism (you may describe it in Dutch)

I can... 

• explain explain the following keyterms: 

-> endemic, indigenous, non-indigenous, native, non-native, exotic, invasive

• give for each key term an example
• explain with 3 arguments how invasive species can harm an ecosystem.

Assignment 

put the words 'indigenous,  non-indigenous, native, non-native, exotic, invasive' in a concept map, starting with the word 'organism' 

An introduced species, alien species, exotic species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, either deliberate or accidental. So, an organism is considered non-native or exotic if it is found in an ecosystem where it did not evolve. A large percentage of the food we produce in this country comes from non-native species. 

Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered "naturalized". The majority of non-native species never causes a problem.

Unfortunately, the few that do cause problems more than make up for the rest of them. This small percentage of non-native species causes a tremendous amount of harm to our native habitats and the plants and animals that inhabit them; to natural areas such as forests, lakes, and rivers that we use for recreation; to agriculture; to our economy; and directly to humans. These harmful exotic or non-native species are called invasive.The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting.

Add 'endemic' in your concept map 

problems created by invasive species
