Producers, Consumers, Decomposers - WordPress.com

Producers & Consumers, It all start with Plants! Types of consumers are

There are Three types of Consumers Carnivores. Herbivores. Omnivores.

Its all about what you eat! Vore = vorax = to swallow or to eat.

1-Herbivores: An animal that eats only plants & other producers.( first-level consumers).

Herbivores: ( herbi = plant or vegetation) 2-Carnivores: Is

an animal that eats mainly other animals. Its also called second-level consumer.

2-Carnivores: carni = meat 3-Omnivores: eat both meat (animals) and plants.

3-Omnivores: omni = all In an Ecosystem: When a grasshopper eats grass, then its

eaten by a snake, then the snake is eaten by a large carnivore such as hawk ( 3rd -level consumer). Each time something eats something else, food energy is transferred from 1 organism to the next.

We can arrange this story & energy transfer in what is called a food chain. How they relate .

What is a food chain ? A is the transfer of energy between organisms in an ecosystem.

It shows how each living thing gets its food. Some animals eat plants and some animals eat other animals. Who eats Who ( only one path).

What is in a food chain ? Producers. Consumers. Decomposers.

Decomposers: When animals & plants die, What happens to the food energy stored in their remains? The remains are broken down & food energy is used by decomposers. So, What is a decomposer??

De= to do the opposite or to undo. Compose= to put together. Decomposer ??

Decomposer is a consumer that gets its food energy by breaking down the remains of dead

organisms ( plants & animals). Decomposers

Decomposers use some of the nutrients as food. The

rest become mixed into the soil. Then plant roots can take up these nutrients. Examples: Earth Worms.

Fungi. Single celled organisms ( protist or bacteria). Decomposers: decomposers are

recyclers. How they relate?? .

Decomposers connect both ends of the food chain. Lets Look at a Food chain Food

Webs A food web is a diagram that shows the relationship

between different food chains in an ecosystem. Who eats who ?? ( many paths ). Food Webs

Because most animals eat more than 1 kind of food , a food web is a model that shows all the possible feeding relationships between organisms living in an ecosystem.

What are the differences between food webs and food chains? A food web is actually several food

chains joined together. Food Webs

A food web is also Who eats Who but showing many paths.
