Answers
Answer:
red-eyed frog
Explanation:
Adaptations are any behavioral or physical characteristics of an animal that help it to survive in its environment...
Answer:
a/polar bear - it has thick layers of fat and fur - for insulation against the cold
b/penguins - Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather.
c/migratory birds - feathered wings and tail.
hollow bone structure that allows for buoyant flight.
efficient respiratory system made up of lungs and air sacs.amazing metabolic abilities (related to the conversion of food into energy)
d/red eyed frog - Red-eyed frog has developed sticky pads on its feet which help it to climb easily on the trees on which it lives. The sticky pads on feet also allow the red-eyed frog to attach itself to the branches and leaves of the trees. The big and bulging bright-red eyes of this frog are an adaptation for protection.
e/toucan bird - It has brightly coloured feathers. It spend most of the time in the holes of big trees. Toucan eats fruits of the trees. Long and large beak: The long and large beak helps a toucan to reach the fruits attached to the ends of even thin branches of trees which are too weak to support its weight.
f/tiger- The tiger's striped coat helps them blend in well with the sunlight filtering through the treetops to the jungle floor. The tiger's seamless camouflage to their surroundings is enhanced because the striping also helps break up their body shape, making them difficult to detect for unsuspecting prey.
g/beard ape - It uses its trunk as a nose because of which it has a strong sense of smell. The trunk is also used by it for picking up food.
h/elephant - They have a strong sense of smell and uses their trunk for smell.They also use their trunk to hold food.They have long ears which help them in keeping cool in a hot and humid climate.Long ears help them in hearing the very soft sounds.They have thickly padded feet which help them in moving silently
