Answer:

1. Explain why predators need to eat more than primary consumers.  

Explanation:

Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.

Can someone please help me
Usimov [2.4K]

Answer:

1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers

1B - Skeletal = bones

1C - Muscular = muscles

1D - Digestive = stomach, large/small intestine

1E - Circulatory = heart, veins and arteries

2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive

3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.
