Answer:
No
Explanation:
This is because oxygen will not be available for breathing and energy will not be released for cellular activities because photosynthesizing organisms have chlorophyll and trap light energy ffrom sunlight , using carbondioxide and water to produce glucose and oxygen. Oxygen is the by product which is the gas that is inhaled by living organisms during respiration and also break glucose to release ATP. Therefore without these organisms, respiration will be difficult.

Answer:
B is the answer...............
The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.
