understanding photosynthesis and
0:02
chemosynthesis photosynthesis and
0:04
chemosynthesis are two processes by
0:06
which organisms produce energy but they
0:09
differ in the energy sources they rely
0:10
on photosynthesis uses sunlight while
0:14
chemosynthesis uses chemical reactions
0:16
to generate energy both processes are
0:19
vital for sustaining life on Earth
0:21
especially in environments with no
0:23
sunlight the role of sunlight in
0:26
photosynthesis photosynthesis is the
0:28
process by which plants algae and some
0:31
bacteria convert sunlight into chemical
0:33
energy using chlorophyll plants absorb
0:36
sunlight and use it to convert carbon
0:38
dioxide and water into glucose and
0:41
oxygen this process is essential for
0:43
life on Earth as it provides the primary
0:46
energy source for most
0:47
ecosystems the energy source in
0:50
chemosynthesis chemosynthesis in
0:52
contrast occurs in environments without
0:55
sunlight such as deep ocean vents or
0:57
underground certain bacteria and ARA use
1:00
chemical reactions often involving
1:02
hydrogen sulfide or methane to produce
1:05
food these organisms convert chemicals
1:08
from their surroundings into energy
1:10
supporting ecosystems where sunlight
1:12
cannot reach photosynthesis in plants
1:15
and algae in photosynthesis plants and
1:18
algae absorb light through pigments like
1:20
chlorophyll converting light energy into
1:23
glucose this process releases oxygen as
1:26
a byproduct which is essential for life
1:28
on Earth photo synthesis is fundamental
1:31
to life in surface ecosystems supporting
1:33
both plant growth and animal life
1:36
chemosynthesis in extreme environments
1:39
chemosynthesis is crucial in extreme
1:41
environments such as hydrothermal vents
1:43
on the ocean floor organisms like tube
1:46
worms and bacteria Thrive here using
1:49
chemicals like hydrogen sulfide to
1:51
produce energy these ecosystems are
1:53
independent of sunlight relying on
1:55
chemosynthesis to sustain life the
1:58
chemical reaction in
2:00
photosynthesis the general equation for
2:02
photosynthesis is 6 Co plus 6 hydrogen
2:06
oxide plus light energy right pointing
2:08
AOC hydrogen oxide plus 6o this equation
2:13
shows how carbon dioxide and water with
2:15
the help of sunlight are converted into
2:17
glucose and oxygen this energy is stored
2:20
in glucose and used by plants for growth
2:22
and reproduction the chemical reaction
2:25
in
2:26
chemosynthesis in chemosynthesis the
2:28
process varies depending depending on
2:30
the chemicals involved a common example
2:32
is the use of hydrogen sulfide Co plus
2:36
plus4 hydrogen sulfide right pointing
2:38
AOC carbon dihydride o plus 4 S + 3
2:41
hydrogen oxide this reaction shows how
2:45
bacteria use hydrogen sulfide and carbon
2:47
dioxide to create organic compounds
2:49
without the need for sunlight the
2:52
ecological significance of both
2:54
processes both photosynthesis and
2:56
chemosynthesis are essential for their
2:58
respective ecosystem
3:00
photosynthesis supports most surface
3:02
dwelling life while chemosynthesis fuels
3:05
life in dark extreme environments both
3:08
processes highlight the adaptability of
3:10
life on Earth to diverse conditions
3:12
ensuring the survival of organisms in a
3:15
wide range of habitats
