switching between sexual and asexual reproduction

Organisms can cause changes in their environment to ensure survival in various ways. This happens through the various processes that cause organisms in different trophic levels to interact from producers to consumers and to decomposers.
A organism with traits that are suited to a certain environment have a better chance of surviving than organisms who's traits are not suited for the environment.
That more organisms are born than the available resources can support leading to a struggle for existence. That all these organisms are variants and that some variants are better adapted to the immediate environment and will survive and reproduce better that the other organisms in that environment. That these beneficial traits that organisms posses are heritable, passed on to progeny and change the allele frequency in populations of organisms over time leading to evolution.
Adaptaion
If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.
Adaptations work by allowing an organism to adjust and change so that they can survive in a changing environment. This allows the organism to live longer.

An organisms fitness is it's ability to survive and reproduce. Adaptations help an organism do so. According to Darwin, natural selection plays a big part in the adaptations that help an animal survive. Natural selection is basically "the best qualities win and reproduce". Over time, the qualities that survived become adaptations, shaping themselves to the changing environment. Because the best qualities lead to successful adaptations, the "favorable" organism will survive and reproduce, increasing its fitness.
An organism highly adapted to its climate will continue to evolve over millenia as its environment is constantly changing
Lichen that is your answer!! :))
Adapting to a new environment means to changeto live. A Chameleon, for example, adapts to its desert environment by changing colors, so it can blend in to its surroundings so its predators wont see it.
they must breathe with lungs instead of gills
"Adaptations" is a noun. It refers to the process of changing or adjusting in order to suit a particular purpose or environment.
