Vocabulary
This process allows plants to make their own food using sunlight, water, and carbon dioxide.
What is photosynthesis?
This type of organism makes its own food and starts most food chains.
What is a producer?
The arrows in a food chain show this.
What is the flow/transfer of energy?
A food web is more accurate than a food chain because it shows this.
What are many possible energy paths?
If the pond dried up, this producer would disappear.
What is algae?
This sugar is created by plants and used as energy.
What is glucose?
This type of organism must eat other organisms to get energy.
What is a consumer?
In a food chain, this type of organism always appears first.
What is a producer?
A food chain shows one path of energy, while a food web shows these.
What are complex interactions between many organisms?
This primary consumer would lose its food source if the algae disappeared.
What is the rabbit?
This term describes anything in the environment that causes an organism to react.
What are stimuli?
An organism that eats only plants is classified as this.
What is a herbivore?
Which organisms in this food chain are carnivores?
A plant → insect → frog → snake → eagle
The frog, snake, and eagle.
This is the main difference between a food chain and a food web.
What is: a food chain shows one energy path, while a food web shows many?
This secondary consumer would be affected because it eats the rabbit.
What is the fox?
This process releases water vapor from tiny pores in plant leaves.
What is transpiration?
An organism that eats other animals is classified as this.
What is a carnivore?
Arrange this food chain correctly: bird, small fish, flower, larger fish.
What is flower → small fish → larger fish → birds?
In a grassland food web, grass is eaten by grasshoppers, rabbits, and mice. Grasshoppers are eaten by frogs, mice are eaten by snakes, and snakes and frogs are eaten by hawks. If the grass population suddenly decreases, which organisms would most likely be affected first, and why?
What is: The grasshoppers, rabbits, and mice would be affected first due to being primary consumers of the grass.
When one part of an ecosystem changes and affects other parts, this occurs.
What is a ripple effect?
This method grows plants without soil by using nutrient‑rich water.
What is hydroponics?
A fox that eats a rabbit which eats grass is an example of this type of consumer.
What is a secondary consumer?
This is the final link in a food chain.
What is a consumer or top predator?
In a grassland food web, grass is eaten by grasshoppers, rabbits, and mice. Grasshoppers are eaten by frogs, mice are eaten by snakes, and snakes and frogs are eaten by hawks. Explain how the removal of hawks could cause a chain reaction affecting at least two other organisms in the food web.
Snake and frog populations would increase because they are no longer being eaten by hawks.
As snake populations increase, mice populations would decrease because more snakes are eating them.
As frog populations increase, grasshopper populations would decrease because frogs eat grasshoppers.
If mice and grasshoppers decrease, grass may increase because fewer primary consumers are eating it.
Explain why the fox would struggle if the pond dried up.
What is: the algae would die, the rabbit would lose its food, and the fox would have less to eat?
