A

matter is neither created nor destroyed it just changes forms as it moves through the cycles.

Q

Describe the 5 abiotic factors and how they affect life.

A

Air- provides oxygen and other necessary gasses
water- provides hydration and places for animals to live
soil- provides nutrients and a growth medium
heat- provides needed warmth
light- needed for photosynthesis and life

Q

Explain how matter moves through ecosystems.

A

Matter is cycled by moving through the lithosphere/geosphere (earth), hydrosphere (water), biosphere (living things) and atmosphere (air).

Q

infiltration/percolation

Study These Flashcards
A

the way water moves into the ground

22
Q

True or false? The water cycle has many paths and no real starting or ending points.

23
Q

97% of water is…

Study These Flashcards
A

Salt water (oceans)

24
Q

3% of water is…

25
Majority of fresh water is…
1. Glaciers/ice 2. then ground water 3. very little in surface water
26
photosynthesis
the process where plants use carbon dioxide, sunlight and water to produce glucose C₆H₁₂O₆ and Oxygen)
27
What equation is this? 6CO2 + 6H20 + Energy = C6H12O6 + 6O2
Photosynthesis
28
Which equation is this C6H12O6 + 6O2 = 6CO2 + 6H2) + Energy
Respiration
29
Can Nitrogen in the atmosphere be used as it is
No, it needs to be fixed
30
where nitrogen fixing bacteria live
root nodules
31
breaking down of dead things- releasing nitrogen in the form of ammonia
decomposition
32
the process nitrogen goes through as it turns into a usable form from bacteria
ammonia/nitrites/nitrates
33
can turn atmospheric nitrogen into a solid
lightning
34
turns nitrogen compounds back into nitrogen gas
denitrifying bacteria
35
the solid lightning creates or nitrites, nitrates
nitrogen compound
36
N₂ in the atmosphere
nitrogen gas
37
live in the roots of legumes and fix nitrogen into a usable form
nitrogen fixing bacteria
38
cellular respiration
the opposite of photosynthesis
39
combustion
burning
40
decomposition
breaking down of dead organisms
41
CO₂
carbon dioxide- a byproduct of respiration- necessary for photosynthesis
42
fossil fuels
coal, oil found in ground- remains of decayed dead plants/animals
43
carbon compounds
any chemical made with carbon- coal, diamond, glucose etc
44
Describe the oxygen cycle
Oxygen is taken in by humans and during breathing we exhale carbon dioxide out, then plants use the carbon dioxide to make oxygen during photosynthesis.
45
Why is the oxygen cycle critical for life
Without it between plants and animals, we would have too much carbon dioxide and not enough oxygen
46
All the living things and nonliving things in a given area
ecosystem
47
Are sunlight and water biotic or abiotic?
abiotic
48
What is the source of almost all energy on earth?
the sun
49
Average weather conditions in an area over time
climate
50
Most organisms are made mostly of what
Water
51
Three processes of the water cycle
Evaporation, condensation and precipitation
