Answer:
about the Trilobites is =Trilobites ( /ˈtraɪləˌbaɪt, ˈtrɪ-, -loʊ-/;[4][5] meaning "three lobes") are a group of extinct marine artiopodan arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 300 million years.[6] . and about the algae is =Algae (/ˈældʒi, ˈælɡi/; singular alga /ˈælɡə/) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as Chlorella and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to 50 metres (160 ft) in length. Most are aquatic and autotrophic and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem, which are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the Charophyta, a division of green algae which includes, for example, Spirogyra and stoneworts.

Answer:
The correct answer is exhaustion stage.
Explanation:
The general adaptation syndrome refers to a three-stage procedure, which illustrates the physiological modifications that the body goes through at the time of stress. The three stages of the syndrome are alarm reaction stage, resistance stage and exhaustion stage.
The exhaustion stage is the outcome of chronic or prolonged stress. Fight with stress for a long duration can drain the emotional, physical, and mental resources to the point where the body no longer exhibit strengths to fight against the stress. Some of the signs of exhaustion are anxiety, fatigue, depression, decreased stress tolerance, and burnout.
The physical consequences of this stage also weaken the immune system and put one at the threat of stress-associated illnesses and even death. As when is in the exhaustion stage, the long-duration of stress elevates the threat of stroke, chronic high blood pressure, depression, and heart disease.
