Q

What are the certain characteristics that all living things have?

A
  • Are made of cells
  • Need energy
  • Grow and develop
  • Reproduce
  • Have adaptations that suit the environment in which they live
17
Q

Define biotic and abiotic.

A

biotic = living
abiotic = nonliving

18
Q

What are some abiotic factors in an ecosystem?

A

Air, Water, Sunlight

(the non-living components of the ecosystem)

19
Q

What are some biotic factors in an ecosystem?

A

People, trees, birds, worms

Anything living

20
Q

What are the differences within a population called?

A

Variations

21
Q

Where is the greatest number of diversity on the planet? Why?

A

Near the equator since the climate is favourable to many different organisms.

For example, it doesnˋt get as cold as the north and south so animals donˋt need to have fancy adaptations to deal with lack of food from everything being covered in snow.

22
Q

Who came up with a system for naming and classifying chemicals?

A

Cardus Linnaeus

23
Q

What language are all organisms classified in? What are the organisms classified by?

A

Latin and based on their physical structure

24
Q

What is the first and second word when naming a species?

A

1: Genus
2: species

25
Q

Closely related species have the same ‘blank’

A

Genus

26
Q

What are the five animal kingdoms?

A

~~~
Animalia (animals)
Plantae (plants)
Fungi (yeasts, molds, mushrooms)
Protista (single-celled organisms)
Monera (Bacteria)

27
Q

What are the sub groups of a kingdom?

A

Kingdom
Phyla
Class
Order
Family
Genus
Species

28
Q

What is the Mnemonic device help remember the sub-kingdoms?

A

Kings Play Cards On Fine Green Silk

29
Q

Why can’t a species survive by itself?

A

Each species is dependent on each other, for example, animals need plants to get their energy.

30
Q

What are the two types of interdependence?

A
  1. symbiosis
  2. predator and prey
31
Q

What are the 3 types of symbiosis?

A

Commensalism, mutualism, parasitism

32
Q

Describe commensalism

A

Where one species benefit and the other is not harmed

33
Q

Describe mutualism

A

A relationship where both species benefit

34
Q

Describe parasitism

A

Where one species benefit and the other is harmed

35
Q

What is a niche?

A

The role of an organism within an ecosystem.

Includes:

  • what it eats
  • what eats it
  • its habitat
  • nesting sights
36
Q

What is interspecies competition?

A

When two or more species need a resource, and neither species benefits from this fight for resources.

37
Q

What is resource partitioning?

A

When two or more species share a resource

38
Q

Why is variation within a species important?

A

Because it increases the chances for an individual to survive if there is environmental change

39
Q

What is natural selection and how does it relate to a specific variation within a species?

A

Natural selection shows which variation is better suited for the environment and more likely to survive
