Heterotrophs
Herbivore, Carnivore, or Omnivore?
Autotrophs
100

All food trains begin with this

What is an autotroph?

or

producer, plant

100

This diagram shows the complex interactions between multiple food chains

100

Heterotrophs are organisms that cannot make their own food; they are also called this because they must consume other organisms for energy

What is a consumer?

100

The hawk in this food web


What is a carnivore?

100

Autotrophs are organisms that have the ability to use photosynthesis to produce their own food, therefore they are also called this

What are producers?

200

Each step in a food chain is called a this, which shows the organism's position in the energy flow of an ecosystem

What is a trophic level?

200

In this food web, the grasshopper is this level of consumer.

What is primary consumer?

200

These consumers only eat plants

What are herbivores?

200

The chipmunk in this food web


What is a herbivore?

200

This is the main source of energy for life on Earth

What is sunlight?

300

algae --> zooplankton --> minnow -->squid --> whale

In this food chain, this organism is the autotroph

What is algae?

300

This organism is a secondary consumer.

What is a lion (show)?

or

Vulture, bird, cheetah, bobcat (show)

300

These heterotrophs eat other animals for energy

What are carnivores?

300

The deer in this food web


What is a herbivore?

300

Photosynthesis allows autotrophs to make their own food, and it also removes this from the atmosphere and releases oxygen

What is carbon dioxide?

or

CO2

400

grass --> mouse --> snake --> hawk

In this food chain, the snake is at this trophic level.

What is a secondary consumer?

400

In this food web, the baboon is this level of consumer

What is secondary consumer (show web)?

or

tertiary consumer (show web)

400

These heterotrophs eat both plants and animals

What are omnivores?

400

The grouse in this food web


What is an omnivore?

400

Only 1% or less of this is used by organisms that use photosynthesis

What is the sun's energy?

500

This level of consumer eats secondary consumers

What is a tertiary consumer?

500

A producer from this food web


What is flowers, grasses, seeds?

500

This class of heterotrophs cause decay by breaking down dead matter and returning nutrients to the ecosystem. An example is mushrooms

What are decomposers?

500

The bear in this food web

What is an omnivore?

500

On land, green plants are the main autotrophs. In water, these organisms are the main autotrophs

What are algae?
