Ecosystems Quiz

What is a food chain?

• A food chain is a circular sequence of organisms where each organism is the food source for the previous organism in the chain.

• A food chain is a linear sequence of organisms where each organism is the food source for the next organism in the chain.

• A food chain is a process where organisms convert sunlight into energy through photosynthesis.

• A food chain is a network of organisms where each organism consumes multiple food sources.

Name the three main components of a food chain.

• predators, prey, and scavengers

• herbivores, carnivores, and omnivores

• producers, consumers, and decomposers

• photosynthesis, respiration, and digestion

What is a producer in a food chain?

• An organism that decomposes dead organisms.

• An organism that consumes other organisms for food.

• An organism that can produce its own food through photosynthesis or chemosynthesis.

• An organism that relies on other organisms for food.

Give an example of a herbivore in a food chain.

• shark

• lion

• rabbit

• eagle

What is a biome?

• A biome is a large geographical area characterized by its distinctive climate, vegetation, and animal life.

• A biome is a man-made structure designed to house a specific type of vegetation and animal life.

• A biome is a term used to describe the study of animal behavior in their natural habitats.

• A biome is a small geographical area characterized by its distinctive climate, vegetation, and animal life.

Name three major biomes found on Earth.

• grassland

• taiga

• ocean

• tundra, desert, rainforest

What is energy flow in an ecosystem?

• Transfer of energy from one organism to another through food chains and food webs.

• The process of energy being released as heat during cellular respiration.

• The movement of energy from the sun to plants through photosynthesis.

• Conversion of energy from one form to another within an organism.

Explain the difference between a food chain and a food web.

• A food chain is a linear sequence of organisms, while a food web is a network of interconnected food chains.

• A food chain consists of only producers, while a food web includes both producers and consumers.

• A food chain represents a single feeding relationship, while a food web shows multiple feeding relationships.

• A food chain is simpler and less complex than a food web, which is more intricate and interconnected.

What is a primary consumer in an energy flow?

• An organism that feeds directly on decomposers.

• An organism that feeds directly on other consumers.

• An organism that feeds directly on producers (plants or algae)

• An organism that feeds directly on sunlight.

Give an example of a secondary consumer in an energy flow.

• shark

• eagle

• snake

• lion
