Explain how a school bus uses all of these energy types.

-Mechanical
-Chemical
-Electrical
-Thermal

Answers

Answer:

Mechanical

94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.

Chemical

school bus uses petroleum as chemical potential energy.

Electrical

An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again

Thermal

They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.

a. Draw a food chain that could exist in your ecosystem.
b. Draw a large arrow to show how the energy flows through your food chain

Answers

Answer:

Explanation:

This is an example

A. The following food chain in a simple terrestrial ecosystem:

Grass → Grasshopper → Frog → Snake → Hawk

B. The energy flow will be directed as follows:

grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)

Food Chain:

Consider the following food chain in a simple terrestrial ecosystem:

Grass → Grasshopper → Frog → Snake → Hawk

In this food chain, the grasshopper is the major producer, the frog is the secondary consumer, the snake is the tertiary consumer, and the hawk is the quaternary consumer.

B. Flow of Energy:

The giant arrow representing the flow of energy through the food chain would start with grasses and progress through each trophic level. Energy moves along the food chain in a way that passes from one organism to another when it is consumed.

The energy flow will be directed as follows:

grasshopper (primary consumer) frog (secondary consumer) snake (tertiary consumer) hawk (quaternary consumer)

The arrows indicate that the sun's energy is taken up by the grass through photosynthesis and then transferred to each successive level when the organism consumes it.
