Q

What is interdependence?

A

Refers to the mutual reliance between organisms within an ecosystem that effects one anothers survival

17
Q

What is Parasitism?

A

Relationship where one organism lives on or in another and feeds of it

18
Q

What is Commensalism?

A

where one organism benefits from the interaction while the other organism is neither helped nor harmed.

19
Q

What is mutualism?

A

A relationship where between organisms, both benefit from each other.

20
Q

What is a symbiotic relationship?

A

A close and long-term interaction between two different species, where at least one of the organisms benefits

21
Q

What is a non-symbiotic relationship?

A

interactions between species that are not close, long-term, or interdependent

22
Q

What are the 7 kinds of relationships, both non-symbiotic and symbiotic

Mutualism, Parasitism, Commensalism

24
Q

What are the three non-symbiotic relationships

A

Competition, Predation, collaboration

25
Q

What is competition?

A

where organisms try to use the same limited/scarce resource

26
Q

What is Predation?

A

When one organism eats another to survive

27
Q

What is collaboration?

A

interactions where species or individuals work together to achieve mutual benefits, improving their chances of survival or resource acquisition.

28

34
Q

What are ways that a fire can help some bush plants?

A

Some plants can be revitalised, and refreshed from burning old outer parts, some release seeds, etc..

Q

What is the purpose of the pyramid of biomass?

A

The pyramid of biomass visualises the amount of organic matter transferred at each trophic level in an ecosystem.

38
Q

Name at least one invasive species and explain how it was introduced into a new ecosystem
