Ecosystems Quiz

What is a food chain?

• A food chain is a circular sequence of organisms where each organism eats the next organism in the sequence.

• A food chain is a sequence of organisms where each organism eats only plants.

• A food chain is a sequence of organisms where each organism eats only meat.

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

Name the different trophic levels in a food chain.

• predators, prey, scavengers, detritivores

• autotrophs, heterotrophs, saprophytes, parasites

• herbivores, carnivores, omnivores, decomposers

• producers, primary consumers, secondary consumers, and tertiary consumers

What is a biome?

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

• A biome is a term used to describe the study of animal behavior.

• A biome is a man-made ecosystem.

• A biome is a small geographical area with similar climate and vegetation.

Give an example of a terrestrial biome.

• Tropical rainforest

• Desert

• Coral reef

• Arctic tundra

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 is a visual representation, while a food web is a written description of the relationships between organisms.

• A food chain represents the flow of energy in an ecosystem, while a food web shows the interactions between different organisms.

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

What is the primary source of energy in most ecosystems?

• water

• wind

• sun

• soil

What happens to energy as it moves up the trophic levels in a food chain?

• Energy stays the same

• Energy decreases

• Energy fluctuates

• Energy increases

What are the three main types of ecological pyramids?

• energy pyramid, biomass pyramid, and pyramid of numbers

• food pyramid, population pyramid, and trophic pyramid

• carbon pyramid, oxygen pyramid, and nitrogen pyramid

• producer pyramid, consumer pyramid, and decomposer pyramid

How does energy flow through an ecosystem?

• Energy flows through an ecosystem through the process of photosynthesis.

• Energy flows through an ecosystem through the process of respiration.

• Energy flows through an ecosystem in a food chain or food web.

• Energy flows through an ecosystem through the process of decomposition.
