Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian populations that apparently has affected about 30% of the amphibian species of the world.<span>[3]</span>
Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

<span>invasive
Invasive species can threaten an ecosystem and the biodiversity of the organism that exist in the present environment when the invasive species increase rapidly in number.
</span><span>Exotic species are a threat to biodiversity because they alter the ecosystem of that area. They share food and habitat resulting in unbalanced ecosystem. Also, habitat destruction destroys the habitat of all the life forms in that area. </span>
If there isn’t multiple choice I think it is the ones in the center ring (the closest ring to the center) of the atoms
Decomposers are necessary in the food chain because they return nutrients to the ecosystem (2)
