Question 1

Assimilation

Answer 1

Animals eat food to get nitrogen

Question 2

Invasive species

Answer 2

No natural predator therefore they can eat many species and take over ecosystems

Question 3

What is a decomposer

Answer 3

Organisms that absorb leftover or waste matter

Question 4

Answer 4

Plant like organisms found in ocean

Question 5

The water cycle

Answer 5

1. Evaporation.
2. Condensation.
3. Precipitation.
4. transpiration.
5. Runoff.

Question 6

Carbon cycle

Answer 6

1. Photosynthesis.
2. Nutrition
3. Animal respiration.
4. Decomposition.
5. Deposition.
6. CO2 gas exchange.
7. Human use.
8. Burning fossil fuels.

Question 7

Nitrogen cycle

Answer 7

1. Atmospheric nitrogen.
2. Assimilation.
3. Ammonification
4. Nitrification

Question 8

What is variation when it comes evolution?

Answer 8

Within the species, there will be variation ex: size of giraffe, long or short neck

Question 9

What is adaptation?

Answer 9

Adaptation refers to a trait or characteristic that enhances the ability of an organism to survive and reproduce in specific environment. These traits develop over generations to the process of evolution by natural selection.

Question 10

Pioneer species

Answer 10

The pioneer species is the initial species to appear during succession

Question 11

What is an invasive species?

Answer 11

Not native to environment and can be harmful

Question 12

Primary consumer

Answer 12

The organisms that eat the producers

Question 13

Secondary consumer

Answer 13

Organism that receive their energy from primary consumers by eating them

Question 14

Tertiary consumers

Answer 14

Organisms that mainly eat other carnivores

Question 15

Analogous structures

Answer 15

Structures which serve similar purposes that have evolved separately, a number of different times

Question 16

Homologous structures

Answer 16

Features with the same structure but different functions

Question 17

Mutualism

Answer 17

A symbiotic relationship in which both organisms benefit

Question 18

Parasitism

Answer 18

A symbiotic relationship in which one organism benefits at the other cost of another

Question 19

Commensalism

Answer 19

A symbiotic relationship in which one organism benefits, and the other receives, neither benefit nor harm

Question 20

Why is carbon important?

Answer 20

All living things on our planet are full of carbon. It is a building block of life molecules.

Carbon dioxide is required for plants to do photosynthesis

Question 21

Nitrogen fixation

Answer 21

Bacteria on plant roots or bacteria, the soil take nitrogen from the atmosphere and converted into ammonia

Question 22

Nitrification

Answer 22

Nitrifying bacteria in the soil convert NH3/NH4 into into NO2 nitrites and NO3 nitrates which plants can use

Question 23

Darwin’s theory

Answer 23

Darwin beliefs, species evolved overtime to adapt to their environment. Those with favorable traits would live to reproduce passing on the favorable trait.

Question 24

Lamarck theory

Answer 24

Lamarck believed that a species could acquire a trait in their lifetime and pass it on to their offspring

Question 25

Charles Darwin theory of natural selection

Answer 25

1. overproduction.(more offspring are produced than can live.) 2. struggle for existence.(limited resources not enough for all.) 3. Variation(within the species there will be variation size, color) 4. Survival of the fittest.(to live long enough to reproduce.) 5. Origin of new species.

Question 26

Why photosynthesis is important

Answer 26

Photosynthesis is important process not only because it is how plans make their food but also because it helps keep carbon dioxide out of the atmosphere

Question 27

Denitrification

Answer 27

The process in which bacteria convert dead matter back into N2 in the atmosphere

Question 28

Population size

Answer 28

Both natality and immigration occurred to increase the population size

Question 29

Endangered species

Answer 29

A species that is close to extinction

Question 30

Threatened species

Answer 30

Species that is not an immediate danger of extinction, but is at risk of low or declining numbers

Question 31

Carrying capacity

Answer 31

The maximum number of species that can be supported by the ecosystem

Question 32

Combustion

Answer 32

Carbon dioxide released to the atmosphere through burning a fossil fuel fuels

Question 33

Emigration

Answer 33

When members of a population leave to a new area

Question 34

Scavengers

Answer 34

Organisms that will eat mostly anything

Question 35

Herbivore/primary consumer

Answer 35

Eats only plants

Question 36

Biogeochemical cycles

Answer 36

The cycling of water, nitrogen, and oxygen that occurs on earth

Question 37

What is produced during photosynthesis?

Answer 37

During photosynthesis glucose is produced and oxygen, gas is released into the atmosphere

Question 38

Photosynthesis

Answer 38

Plants are producers take carbon dioxide from the atmosphere to use
