What is a food chain?
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
True or False: A food chain always starts with a primary consumer.
False
Fill in the blank: The first trophic level in a food chain consists of ______.
producers
What are producers in a food chain?
Producers are organisms that can make their own food, typically through photosynthesis, such as plants.
What role do consumers play in a food chain?
Consumers are organisms that rely on other organisms for food.
Multiple Choice: Which of the following is an example of a primary consumer? A) Lion B) Grasshopper C) Oak Tree
B) Grasshopper
What is a secondary consumer?
A secondary consumer is an organism that eats primary consumers.
True or False: Decomposers are an essential part of a food chain.
True
Fill in the blank: ______ are organisms that break down dead material and recycle nutrients back into the ecosystem.
Decomposers
What is the correct order of a simple food chain?
Producer → Primary Consumer → Secondary Consumer → Tertiary Consumer
What is the difference between a food chain and a food web?
A food chain is a linear sequence, while a food web is a complex network of interconnected food chains.
True or False: All organisms in a food chain are equally important.
True
What is the primary source of energy for most food chains?
The sun
Multiple Choice: Which of the following is NOT a producer? A) Algae B) Rabbit C) Corn Plant
B) Rabbit
What happens to energy as it moves up the food chain?
Energy decreases as it moves up the food chain due to energy loss at each trophic level.

Multiple Choice: Which level of the food chain has the least energy available? A) Producers B) Primary Consumers C) Tertiary Consumers
C) Tertiary Consumers
What is the significance of decomposers in a food chain?
Decomposers recycle nutrients back into the ecosystem, allowing for new plant growth.
True or False: Food chains can be disrupted by environmental changes.
True
Fill in the blank: The ______ level includes organisms that eat primary producers.
