What is the main purpose of the energy pyramid in ecosystem?
To show the flow of energy from producers to consumers.
What’s an autotroph?
Produce own food 
What’s a heterotroph?
Cannot produce its own nutrients.relies on others for nutrients.
What’s a producer?

All other organisms. 
What a decomposer?

What’s a scavenger?
Organisms that feed on the dead animals.
How does the first traffic level supply energy to other consumers?
Their energies relied on to survive in this energy is passed on through the small animals to the big animals which they rely on each other gain that energy.
Photosynthesis is the process by which?
Plants use water and carbon dioxide to produce glucose. 
During respiration?
Organisms convert the energy and glucose into the energy carrying molecule ATP.
 The food web is…
A diagram that shows the transfer of energy from one organism to another in a ecosystem.
The intertidal zone is… 
A rocky shore which is only submerged during high tide
