What is the source of energy in this ecosystem? What path does energy take to get to the hawk?

A Food Chain is a simple model that scientists use to show how matter and energy move through an ecosystem.

A Food Chain is drawn using arrows to indicate the direction in which energy is transferred from one organism to the next.

Each organism in a food chain represents a feeding step, or Tropic Level, in the passage of energy and materials

A food chain represents only one possible route for the transfer of matter and energy through an ecosystem. Many other routs may exist. A Food Web is made up of many interconnected food chains and shows all the possible feeding relationships within a community,

Use the diagram on the right to answer the following questions: Who is the producer in this food web? Algae

How many different food chains involve Squid? 4 What are they? algae  small animals  squid  elephant seal  killer whale & protists algae  squid  killer whale algae  squid  leopard seal  killer whale algae  small animals  squid  elephant seal  leopard seal  killer whale & protists

Using what we know about energy, how much energy would be available to the leopard seal using this food chain if algae begins with 250,000 units? ,000 25,000 2, What about the killer whale? 25 25
