Producers and Consumers
Plants and primary producers are also known as...
What are autotrophs?
The biological process used by producers to create energy using sunlight.
What is photosynthesis?
What are producers?
The amount of living tissue in a trophic level is called this.
What is biomass?
Human activity is often responsible for increasing levels of this element in the atmosphere.
What is Carbon?
Organisms that acquire energy and nutrients from other organisms.
What are heterotrophs?
These organisms get their energy from decaying plant and animal matter.
What are decomposers?
A network of feeding interactions, through which both energy and matter move.
What is a food web?
This term means steps of a food chain or food web; producers always make up the first step.
What are trophic levels?
These are elements that an organism needs to sustain life.
This type of consumer eats decomposers and the organic matter that decomposers produce.
What are detrivores?
How many directions can energy flow through a food chain?
What is one way?
A predator that is at the top of its food chain is known as...
What is an apex predator (tertiary consumer)?
This type of animal is a primary consumer.
What is a herbivore?
This biogeochemical cycle is the only cycle that does not involve the atmosphere.
What is the phosphorus cycle?
This type of producers do not need light to produce energy.
What is Chemosynthetic?
Plants produce energy using sunlight. This produced energy is stored in the form of...
What are carbohydrates?
Secondary consumers may be carnivores or this type of consumer.
What are omnivores?
On average, this much energy is transferred from one trophic level to the next.
What is 10%?
Most of the nitrogen in the atmosphere is in the form of this gas.
What is Nitrogen gas?
Decomposers chemically breakdown organic matter and produce a substance called this, which is decaying plant and animal remains.
What is Detritus?
These organisms thrive in total darkness and use chemosynthesis to produce carbohydrates?
What are bacteria?
Ocean food chains can be very long and usually begin with this organism.
What is phytoplankton?
If there are 100,000 calories of energy available at the primary producer level, this much energy will be available at the secondary consumer level.
What is 1,000 calories?
This is the term used to describe the recycling of matter and nutrients; includes the water cycle, carbon cycle, nitrogen cycle, and phosphorus cycle.
What is Biogeochemical cycles?
