Food Chains

Food Webs and Food Chains

​Classifying Living Organisms

​ 1. Producers- can produce their own food and energy from the sun and water.

​

2. Consumers- gets its food and energy by consuming (eating) other living organisms from a different population.

   ​

3. Decomposers​- get their food and energy by consuming dead organisms.

Herbivore- a consumer that feeds on plants.

​

Carnivore- ​a consumer that feeds on meat.

​

Omnivore- ​a consumer that eats plants and animals.

​

Classifying Consumers

​

Food Chain- shows the flow of energy that gets transfered from one oragnism to another.

​

​

Food Chain​

Every food chain has a predatory prey relationship.

​

This is where one species is hunted as a food/energy source of another speices.​

A food web is made up of many food chains in one ecosystem.
