🌊 Exploring the Marine Ecosystem
The script introduces the marine ecosystem, a vast and diverse environment where plants and animals coexist in harmony. It discusses the ocean's role as the largest habitat on Earth, covering most of the planet's surface and hosting millions of species. The script delves into the unique characteristics of the ocean, including its five major divisions—the Arctic, Atlantic, Indian, Pacific, and Southern Oceans—and highlights the Mariana Trench as the ocean's deepest point. The marine ecosystem is divided into three main layers based on depth and sunlight penetration: the euphotic zone, where sunlight reaches and supports abundant life; the dysphotic zone, where sunlight is limited; and the aphotic zone, a dark, unexplored realm. The script also touches on marine plants like seaweed, algae, sea grasses, and mangroves, which play a crucial role in the ecosystem by absorbing carbon dioxide and releasing oxygen. Additionally, it mentions kelp's significance as a food source and its use in human products. Phytoplankton, tiny marine plants, are highlighted as the base of the ocean's food chain, supporting a wide range of sea creatures, from the smallest fish to the largest whales. The paragraph concludes by emphasizing the variety of marine animals, including the blue whale, the largest animal in the sea, and the unique adaptations of deep-sea creatures like the angler fish.
🛑 Human Impact on Marine Ecosystems
This paragraph addresses the impact of human activities on marine ecosystems, emphasizing both the benefits and the potential harm we cause. It starts by acknowledging the various ways humans utilize the ocean, such as for food, medicine, oil, and recreation. However, it also points out the destructive practices in fishing, such as the use of poisons and dynamite, which can harm marine life beyond the target species. Overfishing of popular and endangered species, despite legal protections, is highlighted as a significant threat. The script then shifts to discuss pollution, explaining how fertilizers, household products, and oil spills damage the ocean's beauty and health. It calls for individual actions to protect the marine environment, such as recycling and preventing chemicals from entering drains, and warns against littering in the ocean, which can poison marine life. The paragraph concludes by summarizing the importance of the ocean and encouraging continued learning about its ecosystems.

good day learners this is easy
engineering
for today's topic we're going to talk
about the marine ecosystem
have you ever dreamed about traveling
inside a submarine
diving from the sea level to the deep
ocean where you could no longer see the
shine of the sun
and you could only see what lies below
what do you think exists there
let's dive in and find out
there is a system in the ocean where
plants and animals live harmonically
in a place and that is called the marine
ecosystems
the marine ecosystem or the ocean is an
area of salty water
that covers most of the earth's surface
and there are millions of different
plants and animals living inside
there are five oceans around the world
the arctic
atlantic indian pacific
and southern oceans
fun fact learners did you know that the
mariana trench
is the deepest part of the ocean in fact
it is equivalent to how tall the mount
everest is
now there are small organisms and
bacteria found in the ocean
seas base and inlets that make a part of
the creatures that live in the marine
ecosystem
there are three main layers of the ocean
based on how deep it is
first is the euphotic or the surface
zone
in this zone sunlight can penetrate or
can be seen
throughout and the water is warm most
plants and
animals live here second
is the dysbotic or the twilight zone
this zone gets some sunlight but not
enough for plants
to survive and the third zone is the
apothic zone
where there is no sunlight at all the
darkest side of the ocean
where unknown creatures could be lurking
[Music]
plants serve a very important purpose in
the life of animals
but did you know that plants can also
grow underwater
some examples of marine plants are the
seaweeds
marine algae and sea grasses
on the other hand mangrove trees which
live on tropical shores are also part of
the ocean ecosystem
these plants absorb carbon dioxide in
exchange
they give up oxygen for animals to
breathe in
marine plants live in the top or
euphotic zone of the ocean
because they need sunlight to create
food through photosynthesis
kelp is a famous type of algae and it
provides food and shelter to ocean
animals
did you know that it is even used by
humans in things like
ice cream and toothpaste
phytoplankton are tiny plants in the
ocean that serve as the food for many
ocean creatures
like smallest fish and even the largest
of whales
speaking of animals what animals found
in the marine ecosystem
i'm sure there are lots and lots of them
that we couldn't even count
since the ocean is vastly wide the ocean
consists of a large variety of animal
life including fish
molochs dolphins seals
wall roses whales crustaceans bacteria
sea animals and many others
fun fact learners did you know that the
largest animal in the sea is the blue
whale
it averages up to 7.6 meters long at
birth
and weighs about 3 tons as an adult it
can easily stretch to the length of a
city bus
and weigh close to 200 tons
now back to the topic most marine
animals stay
in euphotic and dysphotic zones where
they have
access to plants and other ocean animals
to eat
but deep down below the layers there is
life too
and they might look weirdest animals on
earth
one example is the angler fish
fishes like this adapt to the darkest
side of the ocean
in fact the angler fish creates its own
light
to lure their prey and when it is closed
the angler fish just gobbles it up in a
blink of an eye
[Music]
we humans use the ocean a lot whether
it's for food
medicines oil other resources
or just for recreation like swimming and
parties either way
we love the things that the ocean gives
us but the demand for resources from the
ocean
can be destructive to the marine
ecosystems
around the world bad fishing practices
like poisoning and using dynamites to
catch fish
also kills other animals like corals and
small fishes
over fishing popular species and
endangered species are prohibited by law
but some people still do it
[Music]
pollution is also harming the marine
ecosystem
pollutants such as fertilizers and
household products
and even oil spills ruin the beauty of
the ocean
for us there are many simple things that
you can do to help protect the ocean
like recycling and making sure that
chemicals don't go down your household
drains is an
easy way to start don't throw your
garbage into the ocean because fishes
eat it and be poisoned with it
so learners now we've learned important
things about the ocean
and that's it that is all for now i hope
you learned something today
once again this is easy engineering
