Chapter 1 and 2

Question 0

What is Dynamic Equilibrium?

Answer 0

A state of balance. A system in which changes are occurring but the components have the ability to adjust without disturbing the system.

Question 1

What are the three levels of the biosphere?

Answer 1

Lithosphere (Rock)
Hydrosphere (Water)
Atmosphere (Air)

Question 2

What is the Biosphere?

Answer 2

A narrow zone around the earth in which life is found.

Question 3

What is Biotic?

Answer 3

Living components of the Biosphere

Question 4

What is Abiotic?

Answer 4

Non-living components of the Biosphere

Question 5

Define Populations

Answer 5

A group of the same species

Question 6

What is an ecosystem?

Answer 6

It is where biotic and abiotic components interact

Question 7

What is a community?

Answer 7

When more than one population of species are in an area.

Question 8

Arrange the ecosystem, population, and community from smallest to
largest

Answer 8

Smallest - Population
Middle - Community
Largest - Ecosystem

Question 9

What does the term Detrius mean?

Answer 9

Waste left by a living organism. (Including dead remains)

Question 10

How can humans get rid of the population of a species?

Answer 10

Loss of habitat, pollution, UV Radiation, and getting rid of another species interrupting the food chain.

Question 11

What is a food web?

Answer 11

A food web is a food chain but with multiple species and lines.

Question 12

What are trophic levels?

Answer 12

Levels of species on a food chain going from producers, to primary consumers, and then to secondary consumers.

Question 13

What is an autotroph?

Answer 13

It is a producer.

Question 14

What is a heterotroph?

Answer 14

A species that can’t make their own food so they consumer other organisms for their energy.

Question 15

Chemical Equation of Photosynthesis

Answer 15

6CO2 + 6H20 = C6 + H12O6 + 6O2

Question 16

Equation of Cellular Respiration

Answer 16

C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy

Question 17

What are the first two laws of thermodynamics?

Answer 17

1. Energy can be transformed from one to another, it also cannot be created or destroyed.
2. During any energy transformation energy can be lost, nothing is 100% efficient.

Question 18

What is an Ecological Pyramid?

Answer 18

A graph that is used to present energy flow in food chains or webs or it can be used to show the populations of organisms in a food chain.

Question 19

Why are frogs sensitive?

Answer 19

Their skin is semi-permeable so many factors of the environment can harm them such as pollution or even heat.

Question 20

What do Invasive species do?

Answer 20

They are a foreign species that interferes with an ecosystems dynamic equilibrium by killing off native species or having no predators so their population booms.

Question 21

What are indicator species?

Answer 21

Species that are particularly sensitive to the ecosystem so they can be used to indicate something wrong with the health or well being of the environment.
