16
Q

Why is there more diversity closer to the equator?

A

Because the sun’s rays are more concentrated there because its flatter.

17
Q

Who created the system for classifying organisms?

A

Carolus Linnaeus.

18
Q

Whats the name of the system for classifying organisms?

A

Binomial Nomenclature.

19
Q

What language is the classifying system based off of?

A

Latin.

20
Q

How many words does the classifying system use?

A

2.

21
Q

What are the 2 words for the classifying system?

A

Genus and species.

22
Q

Define genus.

A
  • first word.
  • what… kind, or type, of organism.
  • CANIS Rufus
23
Q

Define species (classifying version).

A
  • second word.
  • what species the organism is.
  • Canis RUFUS
24
Q

What’s interdependence?

A

The dependence of 2 or more species on each other.

25
Q

Name 2 things plants provide, and give an example for each.

A
  1. Oxygen

Trees absorb the CO2 we excrete, and give us back oxygen that we use to breath.

26
Q

Give an example of a food chain.

A

Choose one. It’s just the energy transfer between things. Write it down if that helps.

27
Q

What’s symbiosis?

A

An association between members of different species.

28
Q

What are the 3 types of symbiosis?

A

Commensalism, mutualism, parasitism.

29
Q

What is commensalism? Give an example.

A

One benefits, other unaffected.
+/0
Ex. Barnacles on a whale.

30
Q

What is mutualism? Give an example.

A

Both benefit.
+/+
Ex. Bee and flower.

31
Q

What is parasitism? Give an example.

A

One benefits, the other is harmed.
+/-
Ex. Tapeworm and human.

32
Q

What 2 words does the word symbiosis come from? Give meanings.

A 
Sym = together
Bio = alive
33
Q

What is interspecies competition?

A

When different species compete for the same resource or niche.

34
Q

What is a niche?

A

How an organism interacts with its environment and what conditions are best suited to it.
Ex. What it eats, what eats it, where it sleeps, etc.

35
Q

What is a human’s niche?

A

My house, my food, etc.

36
Q

What is resource partitioning?

A

When species change their niche slightly to incorporate other species to avoid competition.
