Plants are NOT heterotrophs. Heterotrophs are organisms that cannot produce their own food; generally these are animals.
The primary consumer in a food chain that would receive 10% of the Sun's energy is the A. mouse.
The Elm tree would receive all 100% of the Sun's energy.
The mouse follows because it eats greens, then the snake eats mice.
The hawk as top in the food chain in terms of the energy from the Sun itself.
Answer;
-Atrial contraction;
Explanation:
-The cardiac cycle comprises all of the physiological events associated with a single heartbeat, including electrical events, mechanical events (pressures and volumes), and heart sounds.The atria and ventricles alternately contract in each cardiac cycle. The pressures in the chambers change greatly over the course of the cardiac cycle.
-During atrial contraction, blood flows from atria (high pressure) to ventricles (low pressure). Similarly, this same pressure gradient exists during ventricular filling.

Explanation: When waves crash, onshore they can make a significant impact on the landscape by shifting entire islands of sand and carving out rocky coastlines. Storm waves can even move boulders the size of cars above the high tide line, leaving massive boulder hundreds of feet inland. Wind is not the only cause of wild waves even tsunamis do, a tsunami is a wave created by a disturbance that displaces a large amount of water, like an earthquake or a landslide, and they often occur in clusters or sets.
