Exploring Food Chains and Their Dynamics

What is primarily eaten by small animals like shrimp in a lake ecosystem?

• Plant plankton

• Fish

• Insects

• Bears

What would likely happen if all the shrimp in a lake were removed?

• Fish populations increase

• Fish populations decrease

• Shrimp populations increase

• No change to the ecosystem

What could be a consequence if bears stopped preying on fish?

• Decrease in fish population

• Increase in fish population

• Fish change their diet

• Shrimp population decreases

• Producers

• Consumers

What process do producers primarily use to create their food?

• Digestion

• Respiration

• Fermentation

• Photosynthesis

Which type of consumer directly eats plants?

• Primary consumers

• Secondary consumers

• Tertiary consumers

• Decomposers

What do secondary consumers primarily eat?

• Meat

• Plants

• Fungi

• Sunlight

Which type of consumer are humans classified as?

• Decomposers

• Omnivores

• Carnivores

• Herbivores

What role do decomposers play in an ecosystem?

• Prey on other animals

• Hunt weaker animals

• Break down dead matter

• Produce food through photosynthesis

What could be the impact of a species going extinct?

• Improved ecosystem stability

• Increased food production

• Potential ecosystem collapse

• No impact on the ecosystem
