Adaptation in Plants & Animals | Environmental Studies Grade 3 | Periwinkle
Summary
TLDRThe video script discusses how various plants and animals have adapted over millions of years to survive in their environments. It provides examples such as camels in deserts, cacti in deserts, pine trees in cold regions, yaks in cold regions, coconut trees in coastal areas, sea turtles near seashores, chameleons blending into their surroundings, gorillas in rainforests, spider monkeys adept at swinging through rainforests, and tall rainforest trees competing for sunlight. The adaptations help the organisms withstand the conditions, evade predators, access food, keep warm or cool, store water, shed snow, lay eggs, and more.

Q & A
How do camels adapt to survive in desert regions?
-Camels have long legs to keep their bodies away from the hot desert sand. They also have humps on their backs to store fat, which allows them to survive for long periods without food, which is scarce in deserts.
How do cactus plants adapt to desert regions?
-Cactus plants have flat green stems to prepare food and store water. Their leaves are reduced to thorns to prevent water evaporation.
How do pine trees adapt to cold regions?
-Pine trees have needle-shaped leaves with waxy surfaces and small surface areas to reduce water loss. Their conical shape and downward-sloping branches allow snow to easily fall off.
How do yaks adapt to living in cold mountain regions?
-Yaks have a thick, wooly covering over their bodies to keep warm. Their hair also helps shed water.
Where are coconut trees mainly grown and why?
-Coconut trees are mainly grown in warm coastal areas because they require high humidity, regular rainfall, and cannot tolerate cold weather.
Where are sea turtles found and why?
-Sea turtles are found swimming close to the surface near seashores where they come ashore to lay their eggs on the same beaches.
How does the chameleon protect itself?
-The chameleon can change its color to match its surroundings to hide from enemies.
Why are gorillas found mainly in rainforests?
-Gorillas are herbivores that feed on the abundant vegetation in rainforests, so they do not need to migrate for food.
How are spider monkeys adapted to get around rainforests?
-Spider monkeys have long, thin limbs and tails to swing easily between trees. They can also hang suspended from branches using their tails.
Why do rainforest trees grow very tall?
-Rainforest trees grow rapidly and very tall in order to compete for sunlight at the canopy level.
Outlines
๐ฒ How Plants and Animals Adapt to Their Environments
This paragraph provides examples of how various plants and animals have adapted over millions of years to survive in their natural habitats. It covers camels in deserts, cacti in deserts, pine trees in cold regions, yaks in cold mountain regions, coconut trees in coastal areas, sea turtles near seashores, and chameleons blending into their surroundings.
๐ต Gorillas and Spider Monkeys in Rainforests
This paragraph discusses two animals found in rainforests - gorillas and spider monkeys. Gorillas are herbivores well suited to rainforests with abundant vegetation. Spider monkeys have adapted with long limbs to swing easily through the trees and tall canopy of the rainforests.

Highlights
Plants and animals have evolved characteristics over millions of years to adapt to their environments
Camels are adapted to survive in hot, dry deserts with long legs to avoid heat and humps to store food and water
Cactus plants in deserts have stems for food production and storage, reduced leaves to thorns to prevent water loss
Pine trees in cold regions have needle-shaped leaves and downward sloping branches to shed snow
Yaks living in cold mountain regions have thick wooly coats to keep warm and shed water
Coconut trees require warm, humid, coastal climates to grow optimally
Sea turtles live mostly in the water but come ashore on the same beaches to lay eggs
Chameleons can change color to blend into their surroundings as protection from enemies
Gorillas in rainforests can thrive on abundant vegetation without migrating for food
Spider monkeys have adapted long limbs and tails to swing easily through rainforest trees
Rainforest trees grow very tall and rapidly to compete for sunlight
Some rainforest trees can reach heights of over 100 feet
Plants and animals adapt over long periods to thrive in their native environments
Specialized adaptations help species meet needs for food, temperature regulation, protection, etc.
Understanding adaptations shows interconnectedness of organisms and environments

plants and animals are adapted to live
in their surroundings
over millions of years they have evolved
certain characteristics to survive in
their environment
let us look at how some plants and
animals have adapted to their
surroundings
camels adapt to desert regions
camels live in desert regions
desert regions are hot
and dry
the long legs keep the camel's body away
from the heat of the hot desert sand
the hump on the camel's back allows the
camel to survive for an extremely long
time without food
in the deserts food is scarce for long
stretches
cactus plants adapt to desert regions
cactus plants are found in the desert
regions
the flat green parts
are its stem
which help it to prepare its food
and store water
the thorns are its leaves
since there is very little water in the
desert
the leaves are reduced to thorns
this helps the plant to reduce
evaporation of water through its leaves
pine trees adapt to cold regions
pine trees grow in cold regions
the leaves of these trees are needle
shaped
they have a small surface area
and a
waxy due to their conical shape
they can stand still
in heavy winds
the branches of pine trees slope
downwards
this natural adaptation makes it easy
for the snow to fall off the branches
so that they do not break due to heavy
snow accumulations
yaks adapt to cold regions
yaks live mainly on the mountains in the
cold regions
they have a thick wooly covering on
their body
this covering helps them to keep their
body warm
the hair
helps them to shed off the water from
their body
coconut trees adapt to coastal areas
coconut trees are grown in tropical
countries all over the world
they are mostly grown in coastal areas
because they require a warm climate
and are intolerant of cold weather
they need high humidity and regular
rainfall
for optimum growth
they grow in soil with rich saline
content
which is found mainly in the coastal
areas
turtles are found near the seashore
sea turtles spend most of their lives in
water
but they come ashore
to lay their eggs
they lay their eggs in only a few places
always on the same beaches
they swim fairly close to the surface of
the water
thus we find turtles near the seashore
chameleon protects itself
the chameleon can change its color to
match its surroundings
this helps it to protect itself from its
enemies
gorillas and spider monkeys are found in
rain forests
gorillas are herbivores that is
plant-eating animals
they are mainly found in rainforests
the rainforests have plenty of
vegetation thus the gorillas do not have
to migrate long distances in search of
food
spider monkeys have long and thin arms
legs and tails
these strong and long limbs help the
spider monkeys to swing effortlessly in
the rainforest
they can hang suspended from trees with
the help of their tails
spider monkeys are one of the best
equipped animals to get around the
rainforest
rainforest trees grow very tall
the trees in the rainforests grow
rapidly
and to great heights
they compete with each other so as to
receive
more sunlight and grow taller
the taller the tree
the more light its leaves will receive
some trees can reach a height of up to
feet
