Ecology

Question 1

Condensation

Answer 1

The process by which water vapor in the air is changed into liquid water. This is crucial to the water cycle because it is responsible for forming clouds.

Question 2

Photosynthesis

Answer 2

Plants use the sun’s energy to convert water and carbon dioxide into food (glucose) for long term storage

Question 3

Cellular Respiration

Answer 3

The process of releasing energy by breaking down glucose and releasing H20 and CO2. All cells burn glucose to get energy

Question 4

Population

Answer 4

A group of individuals that belong to the same species and live in the same area

Question 5

Autorophs

Answer 5

Producers

Question 6

carbon cycle

Answer 6

the movement of carbon from the nonliving environment into living things and back

Question 7

cellular respiration

Answer 7

Process that releases energy by breaking down glucose and other food molecules by using oxygen

Question 8

Anmonium

Answer 8

nitrogen-containing nutrients for plant growth.

Question 9

Nitrogen

Answer 9

Essential for life are numerous organic compounds such as DNA, proteins, and chlorophyll uses this gas is prevalent in the atmosphere but plants and animals cannot use this form directly. It can only be consumed by other organisms or absorbed with the help of bacteria.

Question 10

Biomass

Answer 10

the total mass of organisms at the tropic level

Question 11

energy pyramid (10% rule)

Answer 11

for every trophic transfer after chemical energy, 10% of energy is lost with every trophic level; the other 90% is lost as waste heat

Question 12

glucose

Answer 12

Plants use the energy of the sun to change water and carbon dioxide into a sugar

Question 13

bacteria, phytoplankton, and algae

Answer 13

producers in the ocean

Question 14

Transpiration

Answer 14

the process where plants absorb water through the roots and release it into the atmosphere. This regulates the temperature of the plant and provides water for photosynthesis. It also serves to move nutrients and sugars through the plant’s vascular tissues.

Question 15

Biosphere

Answer 15

Consists of all life on Earth and all parts of the Earth in which life exists, including land, water, and the atmosphere.

Question 16

Community

Answer 16

assemblage of different populations that live together in a defined area

Question 17

Ecological Hierarchy

Answer 17

the order of biotic interactions and relationships in an ecosystem: organism, population, community, ecosystem

Question 18

nitrogen fixation bacteria

Answer 18

a type of bacteria that consumes nitrogen in the air and changes it into a form plants can use (ammonium)

Question 19

denitrifying bacteria

Answer 19

a group of bacteria that helps to convert nitrates or nitrites into nitrogen-containing gases. This conversion is crucial for the atmosphere. It completes the nitrogen cycle by recycling nitrogen into the atmosphere.

Question 20

nitrogen cycle

Answer 20

The transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere
