Feeding Relationships

Producers vs. Consumers

Producers

Make their own food via photosynthesis

Consumers

Get energy by eating producers or consumers

Identify if the following examples are a producer or

consumer

1) Flowering plants

2) Turtles

3) Ants

4) Moss

5) Antelope

Page 4: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Types of ConsumersHerbivoreeats plants

Carnivore eats animals

Omnivoreeats plants and animals

ScavengerFeeds on the remains of another animal

Decomposer eats breaking down dead organisms

Page 5: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Decomposition

Organisms die at ALL LEVELS of the food chain

As organisms die they decompose into organic material. This organic material produces nutrients that producers need

to grow.

Page 6: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Identify if the following examples are a herbivore,

carnivore, omnivore, scavenger or decomposer

1) Bacteria

2) Sharks

3) Deer

4) Raccoons

5) Vulture

nivores

Ex: plants

Herbivores Ex: grasshopper

Carnivores Ex: rat

Carnivores Ex: Snake

Ex: bear

Food Chain

Definition:

One way flow of energy

Example:Grass → Grasshopper → Mouse → Snake

Page 9: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Label the Primary Producer, Primary Consumer, Secondary Consumer, and

Tertiary Consumer in the food chain below.

Grass → Grasshopper → Mouse → Snake

Food Web

Definition:

Network of interconnecting food chains

Represents ALL the possible feeding relationships in an ecosystem

Page 11: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Page 12: Feeding Relationships. Producers vs. Consumers Producers Make their own food via photosynthesis Consumers Get energy by eating producers or consumers

Identify two food chains found in the food web above.

ROLES OF ORGANISMS IN AN ECOSYSTEM Producers and Consumers: Decomposers, Carnivores and Herbivores Producers Consumers (Carnivores) (Herbivores) (Decomposers)

Economics CRCT Review. Producers Producers make things. People, businesses, and governments can all be producers. Consumers Consumers buy the things producers

Photosynthesis An overview 1. Objectives SWBAT describe the process of photosynthesis SWBAT relate producers to photosynthesis 2

Producers, Consumers, and Decomposers

Autotrophs= producers: organisms that use photosynthesis to make food Heterotrophs= consumers: organisms that must eat other organisms to get their energy

Ecosystems. Primary producers Sun Ecosystems Primary consumers Secondary consumers Primary producers Sun

Chapter 8 Photosynthesis. Trophic Roles Autotrophs produce organic molecules from CO 2 & inorganic raw materials producers plants Heterotrophs consumers

Producers, Consumers, Decomposers

The Producers PhotosynthesisThe Producers Ecological classification • Produce the food (photosynthesis) • Condition the environment • Create shelter and habitat Photosynthesis

Producers and Consumers

The Working Cell: Energy from Food Chapter 7 Sunlight Powers Life Autotrophs: self-feeders –Photosynthesis –Producers Heterotrophs: other eaters –Consumers

Autotroph Autotroph (Producers) Make their own food Photosynthesis Chemosynthesis - Plants - Some bacteria & protistsHeterotroph (Consumers) Energy obtained

Ecosystems. Feeding level vocab Producers are the autotrophs of an environment Mostly by photosynthesis Consumers are the heterotrophs of the environment
