Producer & Consumer Roles
This type of organism gets its energy directly from sunlight to make its own food.
What is a producer?
In a food chain diagram, these symbols represent the direction that energy is transferred from one organism to the next.
What are arrows?
The green pigment inside plant cells that absorbs sunlight energy.
What is Chlorophyll?
These two things are taken in to the cells to start cellular respiration.
What is glucose and oxygen?
Animals that eat both plants and other animals (such as humans, pigs, and raccoons).
What is a omnivore?
Organisms like turkey vultures and crows that get their energy from eating dead meat.
What is a scavenger?
In the food chain Grass ➔ Deer ➔ Wolf ➔ Vulture ➔ Bacteria, this organism acts as the secondary consumer.
What is the wolf?
The two main output products generated by plants during photosynthesis.
What are glucose and oxygen?
This is another name for the energy produced by cellular respiration.
What is ATP?
An example of a secondary consumer that is strictly a carnivore.
What is a ......?
Earthworms, bacteria, and fungi belong to this group known as "nature's recyclers."
What are decomposers?
In a marine food web containing seaweed, limpets, crabs, and gulls, seaweed and phytoplankton fulfill this role.
What are producers?
The gas that plants take in from the air to perform photosynthesis.
What is carbon dioxide?
These are the three things that are produced by cellular respiration.
Carbon dioxide, ATP, water
The original source of almost all energy flowing through terrestrial and aquatic ecosystems.
What is the sun (sunlight)?
A consumer that gets its energy directly from producers is called this type of consumer (e.g., grasshoppers, mice, deer).
What is a primary consumer (or herbivore)?
If a disease kills off a major predator (like crabs) in a food web, this immediately happens to the population of their primary prey (like mussels).
What is an increase in population (due to fewer predators)?
The primary chemical form of sugar that plants produce to store energy.
What is glucose?
This is another name for carbon dioxide.
CO2
These organisms consume dead organisms.
What are scavengers?
Bacteria and fungi are examples of this group.
What are decomposers?
This is organism is usually at the end of the food chain but is not a predator.
What is bacteria?
What is sunlight, water, carbon dioxide?
This is the name of the process organisms use to produce energy.
What is cellular respiration?
When a prey population increases after its main predator dies off, their numbers eventually level out due to environmental constraints known as these two factors.
What is carrying capacity and limiting factors?
