Principles of Ecology

Question 1

What is an atom? (1st level)

Answer 1

Atoms make up molecules (ex. carbon)

Question 2

What is a molecule? (2nd level)

Answer 2

The building blocks of life (ex. carbon dioxide)

Question 3

What is a macromolecule? (3rd level)

Answer 3

A large molecule (ex. proteins)

Question 4

What is an organelle? (4th level)

Answer 4

The organs of a cell (ex. hemoglobin)

Question 5

What is a cell? (5th level)

Answer 5

The smallest functional unit of an organism (ex. red blood cell)

Question 6

What is tissue? (6th level)

Answer 6

Many cells working together (ex. mussel tissue)

Question 7

What is an organ? (7th level)

Answer 7

Tissues organized and working together (ex. heart)

Question 8

What is an organ system? (8th level)

Answer 8

Organs that work together to perform certain functions (ex. circulatory system)

Question 9

What is an organism? (9th level)

Answer 9

Organ systems working together (ex. Nathanle)

Question 10

What is a population? (10th level)

Answer 10

All of a certain organism living in a certain area (ex. elk population)

Question 11

What is a community? (11th level)

Answer 11

Different populations interacting (ex. forest community)

Question 12

What is an ecosystem? (12th level)

Answer 12

A community with abiotic factors (Yellow Stone)

Question 13

What is a biome? (13th level)

Answer 13

An ecosystem with similar climates (ex. a desert)

Question 14

What is a biosphere? (14th level)

Answer 14

Wherever there is life/ worldwide sum of all ecosystems (ex. Earth)

Question 15

What are biotic factors?

Answer 15

The living organisms/ factors in an ecosystem (ex. Nathanel)

Question 16

What are abiotic factors?

Answer 16

The non-living factors in an ecosystem (ex. water)

Question 17

What is a heterotroph?

Answer 17

Organisms that get their energy/food from other organisms

Question 18

What is the difference between a food chain and a food web?

Answer 18

A food chain follows one path of energy while a food web is more complex and is a system of connected food chains

Question 19

What are the names of each trophic level?

Answer 19

Producers (level 1), Primary consumers (level 2), Secondary consumers (level 3), Tertiary consumers (level 4) (Bonus: Apex predators- have no other predators)

Question 20

What is the role of decomposers?

Answer 20

They break down dead organisms into nutrients for producers

Question 21

How much energy is passed on from level to level?

Answer 21

10%

Question 22

What are the three types of symbiotic relationships?

Answer 22

Parasitism +/-, Mutualism +/+, Commensalism +/0

Question 23

What is parasitism?

Answer 23

One organism lives on or inside an organism causing the host harm while the parasite benefits

Question 24

What is mutualism?

Answer 24

A relationship between two species where both benefit

Question 25

What is commensalism?

Answer 25

A relationship between two species where one species benefits while the other is neither harmed nor benefits

Question 26

What is competition?

Answer 26

The rivalry between/among living this for territory, resources, food, etc.

Question 27

What is predation?

Answer 27

The preying of one organism on another

Question 28

What is interspecific competition?

Answer 28

Competition between different species

Question 29

What is intraspecific competition

Answer 29

Competition within the same species

Question 30

What are adapatations?

Answer 30

A feature of an organism that gives it a benefit or advantage

Question 31

What are structural adaptations?

Answer 31

Physical features of the body that assist in some way with survival or reproduction

Question 32

What are behavioral adaptations?

Answer 32

Things that an organism does which gives it some sort of benefit, mostly innate behaviors

Question 33

What are physiological adaptations?

Answer 33

Things an organism’s body does without necessarily having to consciously tell it to do so
