Biomes and ecosystems are both important concepts in ecology but differ in scale and scope. This video explores the differences between these terms and how they relate to the natural world.

understanding the concept of biomes a
0:02
biome is a large geographic area
0:05
characterized by specific climatic
0:07
conditions vegetation types and wildlife
0:10
examples include forests deserts
0:12
grasslands and Tundras biomes are
0:15
generally categorized based on
0:17
temperature precipitation and the
0:19
dominant plant species found in the area
0:21
and they can span across several
0:23
countries or continents defining
0:25
ecosystems and their scope an ecosystem
0:28
refers to a smaller localized community
0:31
of living organisms interacting with
0:32
their physical environment such as water
0:35
air and soil it includes both biotic
0:38
living components like plants animals
0:41
and microorganisms and abiotic
0:43
non-living components like climate
0:46
nutrients and energy flow ecosystems can
0:49
exist within biomes size and scale
0:52
biomes versus ecosystems the size of a
0:55
biome is much larger than that of an
0:57
ecosystem a biome can span vast areas
1:00
covering thousands of square kilometers
1:02
and even multiple continents ecosystems
1:06
however are much smaller and can be
1:08
found within biomes such as a forest
1:10
ecosystem within a temperate forest
1:12
biome or a freshwater ecosystem within a
1:14
lake biome the role of climate in biomes
1:18
climate plays a dominant role in shaping
1:20
biomes factors such as temperature
1:23
precipitation and seasonal variations
1:26
determine which plant species thrive in
1:28
a particular biome and conse consquently
1:30
the types of animals and other organisms
1:32
that can inhabit it biomes like deserts
1:35
rainforests and Tundras have distinct
1:37
climate patterns that influence their
1:39
ecological makeup the role of species in
1:43
ecosystems in an ecosystem species
1:45
interact with each other in their
1:47
environment to create a functioning unit
1:49
these interactions such as Predator prey
1:52
relationships symbiosis and competition
1:55
influence the biodiversity within an
1:57
ecosystem the specific species present
2:00
in an ecosystem help regulate energy
2:02
flow nutrient cycling and the overall
2:04
balance of the system spatial
2:07
distribution of biomes biomes are
2:09
distributed across the globe based on
2:11
latitude and elevation for example
2:14
tropical rainforests are typically found
2:16
near the equator while Tundras are
2:18
located closer to the poles the location
2:21
of a biome is determined by the global
2:23
climate system and is consistent over
2:25
large areas regardless of individual
2:27
ecosystems within it the functionality
2:30
of ecosystems ecosystems are Dynamic
2:33
systems where energy and nutrients flow
2:35
through food chains and webs from
2:37
producers plants to Consumers herbivores
2:41
carnivores and
2:42
decomposers they are critical for the
2:44
recycling of nutrients and maintaining
2:46
the balance of Life ecosystems are
2:49
constantly changing due to factors like
2:51
climate human activity and natural
2:54
disturbances examples of biomes and
2:56
their characteristics some common biomes
2:59
include the the tundra desert grassland
3:02
temperate forest and tropical rainforest
3:05
each biome has distinct features deserts
3:08
are dry and hot with minimal vegetation
3:10
tropical rainforests are humid and
3:12
support a wide variety of species
3:15
grasslands are open treeless areas
3:17
dominated by grasses each biome supports
3:20
ecosystems suited to its climate
3:23
examples of ecosystems and their
3:24
functions an ecosystem can be as small
3:27
as a pond or as large as a forest
3:30
for instance a coral reef ecosystem in
3:32
the ocean supports marine life like fish
3:35
corals and invertebrates while a forest
3:37
ecosystem supports a wide range of plant
3:40
and animal species each ecosystem
3:43
operates through energy transfer and
3:45
nutrient cycling that supports the
3:46
organisms within it how biomes and
3:49
ecosystems interact biomes and
3:52
ecosystems are interconnected with
3:54
ecosystems forming within the larger
3:56
biome framework a biome provides the
3:59
overall environmental conditions while
4:01
ecosystems function within those
4:03
conditions for example a forest biome
4:06
will host various ecosystems like
4:08
freshwater streams or forest floor
4:10
habitats where diverse organisms Thrive
4:13
