Grade 6C
Lesson objectives

Know how food chains can be used to
represent feeding relationships in a habitat.

Know that food chains begin with a plant (the
producer), which uses energy from the sun.

Know and understand the terms ‘producer’,
‘consumer’, ‘predator’ and ‘prey’
Can you remember what we mean by the word
‘habitat’?
Habitat

A habitat is a place where living things live
and find their needs.
 Different
habitats on Earth:
1. Aquatic habitats: ocean, lake, pond, river..
2. Terrestrial habitats: prairie, forest, desert,
mountain….
Food chain

A food chain is a series of events in which
one organism eats another and obtains
energy.

A food chain shows one possible path
along which energy can move through an
ecosystem.
What is in a food chain?
 Producers
 Consumers
 decomposers
producers
Make their own food by photosynthesis.
 Green plants use energy from the sun to
make their own food.
 Producers are on the bottom of the food
chain.

Photosynthesis.
Consumers
Consumers hunt, gather, and store food
because they cannot make their own.
 consume= to eat or to feed

Three types of consumers:
1. Herbivores
2. Carnivores
3. Omnivores

Herbivores: animals that eat only plants
Carnivores: animals that eat only meat
Omnivores: animals that eat both meat and
plants
Consumers are also classified as:
•Primary
consumers: are consumers that feed off
producers.
•Secondary
consumers: are consumers that feed on
primary consumers and sometimes consume producers.
•Tertiary
consumers: are consumers that can feed off
secondary and primary consumers and sometimes
consume producers.
•Quaternary
consumers
Decomposers:

Organism that break down dead animals
and plants and return the nutrients to the
soil.
Predator and prey

Predator: an animal that captures and eats
other animals.

Prey: the animal that is captured and
eaten.
Run for your life!
Let’s look at a food chain
it is a simplified way to look at the energy that passes from
producers to consumers.
What is a food web?
A more realistic way of looking at the
relationship of plants and animals in an
environment.
 We use arrows to show feeding relationship.


Several food chains linked together.

A predator from food chain maybe linked to
the prey of another food chain.
