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.
Takeaways
- 😲 Plants and animals adapt over time to survive in their environments
- 🐫 Camels are well-adapted to hot, dry deserts with long legs, humps for water storage
- 🌵 Cacti reduce water loss with reduced leaves and stems for photosynthesis
- 🌲 Pine trees withstand cold and snow with waxy, needle-shaped leaves
- 🐮 Yaks have thick wool and coat to survive frigid mountain climates
- 🌴 Coconut trees require warm, humid, coastal climates to grow
- 🐢 Sea turtles live in oceans but lay eggs on coastal beaches
- 🦎 Chameleons camouflage themselves by changing color
- 🦍 Gorillas thrive in rainy forests with abundant vegetation
- 🐒 Spider monkeys have adapted limbs to swing through rainforest canopies
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.
