The question assumes that wallabies all live in the grasslands. They don't. In fact, very few wallabies live in the grasslands. Wallabies are better adapted to rocky slopes and hillsides, or thick bushland where they can move agilely around and between trees to evade possible predators.
Wallabies are particularly agile, more able to hop up and down slopes than their larger relatives, the Red and Grey kangaroos. Wallabies have large, strong tendons in their hind legs which act as "springs", and they hide in bushland where they can quickly and easily escape from potential predators, dodging back and forth between trees and up and down slopes.
The mother wallaby spends most of her adult life pregnant, but in drought times in her habitat (again, not usually the grasslands), she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished. The mother can also produce two different types of milk to suit the needs of two different aged joeys. She might have a more mature joey that spends less time in the pouch, while a very young embryo has attached itself to a teat. Each joey has different milk requirements - which the mother is able to supply.
Wallabies have the ability to hear very well: they can twitch their ears independently around to determine the direction of specific sounds, much as a cat does.

The adaptations that euglena have helps it to survive in its habitant. One such feature is the flagellum which is similar to a tail and helps it in movement.

green alga grows on it and that makes it camouflage.
Traits that enable an organism to survive and reproduce are known as adaptations. Each organism has specific adaptations suitable for its environment.
Fish have many adaptations that help them survive their environment. Their gills are part of their adaptations that helps them in respiration. Fins also come in handy for purposes of mobility.
Girraffe's are tall, which means they can see predators from far.

The color of their coat helps them blend into the environment so that they can stalk prey.
Not necessarily. While adaptations can help an organism survive and reproduce in its environment, they may not always be beneficial in all situations or environments. Changes in the environment or interactions with other species can render an adaptation less useful or even harmful over time.
Camouflage is an adaptation because it helps the organisms to survive without being prey to other animals or organisms. Adaptations help an animal to survive so having camouflage helps the animal not to be eaten!
