The amount of energy available as one moves up the energy pyramid decreases substantially.
Explanation:
At each trophic level, energy is lost primarily through heat loss and respiration.
In the image below, 100% of the energy from the plant is not available to the deer. As we move further from the primary producer (in the image below, the green plant), less and less energy is transferred.

According to Selye (1956, 1974), which stage of reaction to stress stimulates the body to send messages from the hypothalamus to
Brums [2.3K]

Answer:

The alarm reaction stage

Explanation:

According to Selye, there are three stages of reaction to stress conditions. These are namely the alarm reaction stage, the resistance stage, and the exhaustion stage.

The alarm reaction stage is the first stage of stress reactions which includes perception of stress conditions. The hypothalamus sends signals to the associated glands and organs to prepare for the defensive responses.

The adrenal gland receives a signal to secrete the stress hormones while organs such as the liver are signaled to increase the glucose formation which in turn would serve as fuel during stress conditions.
