Energy Transfer

• Food Chains• Food Webs• Energy Pyramids

How energy (food, nutrients) move through an ecosystem


Energy Pyramid

Shows how energy moves through an ecosystem.

Each level has less than the level below.

called Trophic levels.


Trophic Levels


Trophic LevelsEnergy moves from one organisms to another when it is eaten



Each step in this transfer of energy is know as a trophic level



Each step in this transfer of energy is know as a trophic level

The main trophic levels are producers, consumers, and decomposers


Producers


• A groups of organisms that can use the energy in sunlight to convert water and carbon dioxide into Glucose (sugar/food)

Producers



• Called Producers because they produce all of the food that consumers use

Producers



• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planet

Producers



• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planet• not all producers have leaves but all use photosynthesis

Producers



• Called Producers because they produce all of the food that consumers use• Without producers, there would be no life on this planet• not all producers have leaves but all use photosynthesis

• Plants and Algae

Producers


Consumer


Consumer• Organisms that do not make their own food


Consumer• Organisms that do not make their own food• Must eat to survive


Consumer• Organisms that do not make their own food• Must eat to survive• Consumer because they consume other

organisms in order to live


– feed on the tissue of dead organisms (both plants and animals)

Vultures, Crows, and Shrimp

Scavengers


Consumers which eat ONLY plantshave flat teeth good for grinding food

Herbivores


CarnivoresConsumers which eat mostly meat

have sharp teeth good for ripping and tearing meat


Consumers which eat BOTH plants and animalshave both types of teeth

Omnivores


consumers which absorb any dead material and break it down into simple nutrients or fertilizers

Essential to making soil rich enough to support producers!

Decomposers
