Answer:
A matured community has balanced energy flow,organic structures are diverse with greater diversity
Explanation:
The ecological successions composed of plants like herbs and shrubs,grass.The herbivores survive by eating plants as their main food. An ecosystem with abundant species population finally becomes a community. A fully matured community has greater diversity of species,organic structures and a balanced energy flow.The levels and principles in ecological succession is very significant to human beings.
Answer:D
Explanation:
Cellular metabolism involves series of orderly sequences of controlled biochemical reactions, in which organisms convert biochemical energy from food nutrients into ATP energy currency of the cell and then release waste products.
Cellular respiration is a process where carbohydrates are broken down to release energy for cellular activities and CO2 is released as byproduct.
Animals breath in oxygen and exhale carbon dioxide a byproduct of cellular respiration.
Chemical equation 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Answer:
alarm reaction
Explanation:
In Selye's general adaptation syndrome theory of stress, the initial response of the autonomic nervous system to a stressor occurs in the alarm reaction phase.
The Alarm Reaction is subdivided into two states, the shock phase and the counter shock phase. The physiological changes in the shock phase, when the individual experiences the stressor stimulus, are very exuberant.
During the Alarm Reaction the so-called Autonomic Nervous System (ANS) actively participates in the set of physiological changes. The ANS is a complex neurological ensemble that autonomously controls the entire internal environment of the body through activation and inhibition of the various systems, viscera and glands.
Also during the moment of acute stress stimulation (Alarm Reaction Shock Phase), a part of the Central Nervous System called Hypothalamus promotes the release of a hormone, which in turn stimulates the pituitary gland (which makes part of the hypothalamus) to release another hormone, ACTH. The latter gains the bloodstream and stimulates the adrenal glands for cortisol secretion.
