The image above shows the trophic (food) levels of the energy pyramid and the amount of biomass energy lost at each level traveling upward, resulting in the pyramid shape. Each level is the same height and the available energy is represented by the width of each level.
Answer:
A
Explanation:
Pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart. Before this, the heart pumps deoxygenated blood to the lungs through the pulmonary artery. In the lungs, this blood expels carbon IV oxide and takes up oxygen. Haemoglobin in the Red Blood Cells is responsible for this. In the heart, this oxygenated blood is pumped by the left ventricle to the rest of the body through the aorta artery. This oxygen is significant in cellular respiration in tissues.
Autotroph are producers. they produce their own light, water, and carbon dioxide. in the trophic levels, autotroph is considered the first level of the trophic levels otherwise known as producers. all food chains start with an autotroph. if there was an increase in autotroph, then there will be an increase in the animals that eat them. if there was a decrease in autotrophs, then the entire food chain will be affected. the animals depending on that certain type of autotroph will then have to find another food source, or they will eventually die of starvation
Answer:
H2O
Explanation:
The chemical formula of water is H2O . which means two hydrogen atoms and one oxygen atom in each molecule of water.
Equation:
The equation for H20 is H2O= H2+02.
