Category 1
This is an essential part of the ecosystem, as it creates food through photosynthesis that fuels the entire food chain.
Producer
This is a type of sugar that is produced by plants through photosynthesis and used as a source of energy.
Glucose
An animal that eats plants to meet its energy needs.
HERBIVORE
A carbohydrate that living things break down to get energy.
SUGAR
An animal that eats organisms that have already died.
SCAVENGER
This is the process by which producers use sunlight, water, and carbon dioxide to create energy in the form of glucose.
Photosynthesis
This is a method of growing plants without soil, using nutrient-rich water instead.
Hydroponics
A living thing that makes its own food.
PRODUCER
A living thing that gets energy by eating other organisms for food.
CONSUMER
A single living thing.
ORGANISM
This is the final link in the food chain, as it consumes other organisms for energy.
Consumer
This is what organisms respond to in their environment, such as changes in temperature or light.
Stimuli
A series of organisms listed in a way that shows which is a food source for another.
FOOD CHAIN
Multiple connected food chains in an ecosystem.
FOOD WEB
An organism that breaks down dead plant and animal matter and returns nutrients to the soil.
DECOMPOSER
This is a series of organisms in which each one is eaten by the next, starting with a producer and ending with a consumer.
Food chain
This is the process by which water is absorbed by plant roots and then released into the atmosphere through tiny pores in the leaves.
Transpiration
The process used by producers to make glucose and oxygen from sunlight, water, and carbon dioxide.
PHOTOSYNTHESIS
The action of clearing a wide area of trees.
DEFORESTATION
The continuing chemical reactions in living things that release and use energy.
METABOLISM
This is made up of living organisms and their physical environment, all of which interact with one another.
Ecosystem
What is the main difference between a food chain and a food web?
A food chain shows the flow of energy from one organism to another, while a food web shows the complex interactions between many organisms.
All living and nonliving things that interact in a given area.
ECOSYSTEM
The release of water vapor through tiny openings in plants’ leaves.
TRANSPORATION
A form of sugar made by plants through the process of photosynthesis.
