Carbon

Answer 1

Element that is a building block of life

Question 2

Atmosphere

Answer 2

gases around the earth

Question 3

Fossil Fuels

Answer 3

Oil, Coal, Natural Gas
Used to be ancient life
Take millions of years to form

Question 4

Carbon Dioxide

Answer 4

Gas found in our atmosphere

Question 5

Greenhouse gas

Answer 5

Carbon Dioxide, Methane and Nitrous Oxide
They keep infrared radiation from escaping the atmosphere. Warms the earth.

Question 6

Producer

Answer 6

Organism that makes its own food through photosynthesis

Question 7

Consumer

Answer 7

An organism that has to eat other organisms for food. It can not make its own food.

Question 8

Food Chain

Answer 8

A model that shows how energy moves from a single producer to a top predator

Question 9

Food Web

Answer 9

A model of energy transfer that shows how plants and animals, within an ecosystem, are interconnected.

Question 10

Trophic Level

Answer 10

Each step or level on the energy pyramid

Question 11

Energy Pyramid

Answer 11

A model that shows the amount of energy available at each trophic level

Question 12

Primary Producer

Answer 12

First Trophic Level
Organisms that made food from photosynthesis or chemical energy
Use light energy to make their own food

Question 13

Autotroph

Answer 13

An organism that makes its own food

Question 14

Primary Consumers

Answer 14

Second Trophic Level
Eat only Primary Producers
Herbivores

Question 15

Heterotroph

Answer 15

Must eat other organisms for food.
Can not make their own food.

Question 16

Secondary Consumer

Answer 16

Eat primary consumers and Primary Producers
Can be carnivores or omnivores

Question 17

Carnivore

Answer 17

Only eats other animals (consumers)

Question 18

Omnivore

Answer 18

Eats animals and plants (consumers and producers)

Question 19

Tertiary Consumer

Answer 19

Trophic Level 4
Eats secondary consumers
Usually a carnivore

Question 20

Quaternary Consumer (Apex Predator)

Answer 20

Eat Tertiary consumers
They are apex predators because they are not prey to other animals

Question 21

Decomposer

Answer 21

Feed on dead organisms
Break down dead plants and animals and return the chemicals to the ground.

Question 22

10% Rule

Answer 22

When energy is passed from one trophic level to the next, only 10% of the energy is passed on.

Question 23

Herbivore

Answer 23

Organisms that only eat plants (producers)

Question 24

Combustion

Answer 24

Burning organic material
Carbon can be released into the atmosphere by burning trees or fossil fuels

Question 25

Photosynthesis

Answer 25

The process that plants use to turn light energy, carbon dioxide, and water and make glucose and oxygen.
Plants take carbon dioxide out of the atmosphere and store carbon in themselves in the form of glucose.

Question 26

Animal and plant respiration

Answer 26

Animals and plants release carbon dioxide into the atmosphere through cellular respiration

Question 27

Carbon Sink

Answer 27

Anything that absorbs more carbon than it releases

Question 28

Carbon pools

Answer 28

Reservoirs of large amounts of carbon. Are able to release or take in carbon.

Question 29

Decomposition

Answer 29

Decomposers break down dead matter and carbon is returned to the soil, air, or water.

Question 30

Carbon Source

Answer 30

Anything that releases more carbon that it absorbs.
