Both of these types of actions protect species from preditors.
Mimicry
Mimicry can help animals survive by allowing the animal to avoid being eaten. It can act like a predator and scare away its own predators. There are many such examples of animals acting like something else to survive.
By helping them look like a different animal, therefore the animals will not want to eat them.
It can help animals by giving the food water and shelter and some structures are adaptation
NOTHING!
how natural selection help some species to survive and few got extinct
yes
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
Three-toed sloths do not exhibit mimicry in the traditional sense, as they do not imitate other species for defense or survival. However, their slow movements and greenish fur, which hosts algae, help them blend into their surroundings, providing camouflage from predators. This adaptation allows them to remain inconspicuous in their natural habitat, effectively serving a similar purpose to mimicry.
Adaptation is how creatures respond to environmental changes, whether that be in their habitat, or in their predators or prey. Adapting will help them survive better.
Reproduction does not help a species to survive, it allows for a species to survive by replacing the ageing population. Without reproduction a species would cease to exist within 1 generation. By reproducing, the species adds to it's population, which helps the species to survive for a longer period of time, because they will not be killed off as easy and will not go extinct:)
Mimicry helps a robber fly survive by allowing it to closely resemble other insects, particularly those that are unpalatable or dangerous to predators, such as wasps and bees. This resemblance deters potential threats, as predators may avoid attacking what they perceive as a harmful insect. Additionally, the mimicry can aid in ambushing prey, as other insects may not recognize the robber fly as a predator. Overall, mimicry enhances both its protection and hunting efficiency.
