Explanation:
The prairie community is dominated by the grass and vegetation cover. Thus the lower most trophic level in the prairie ecosystem are the short and tall grasses. They produce major source of biomass for the herbivores of the food chain. They consume the grasses can be designated as primary consumers of the food chain. Also the producers which are grasses which make up the large amount of biomass will provide a source of food for the consumers. They will receive 100 percent energy from the sun and they will utilize 90 percent of it to make their food by the process of photosynthesis. Only ten percent of energy is transferred to the next trophic level.
The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.
The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.
