What is a food chain?
A food chain is a method of cooking.
A food chain is a group of people eating together.
A food chain is a sequence of organisms each dependent on the next as a source of food.
A food chain is a type of plant.
How does a food web differ from a food chain?
A food web is a simple line of energy transfer, while a food chain is a complex network.
A food web is a complex network of interconnected food chains, while a food chain is a linear sequence of energy flow.
A food web only includes plants, while a food chain includes both plants and animals.
A food web shows only predator-prey relationships, while a food chain shows all organisms in an ecosystem.
What are producers in an ecosystem?
Producers are decomposers that break down organic matter.
Producers are typically plants and some microorganisms that convert sunlight or inorganic compounds into energy.
Producers are organisms that rely solely on other organisms for energy.
Producers are animals that consume plants for energy.
Define symbiosis and give an example.
The competition between two species for the same food source.
The interaction between a cat and a mouse.
The relationship between sharks and remora fish.
An example of symbiosis is the relationship between bees and flowering plants.
What type of relationship is mutualism?
A symbiotic relationship where both species benefit.
A parasitic relationship where one species benefits at the expense of another.
A commensal relationship where one species benefits and the other is unaffected.
A competitive relationship where both species struggle for the same resources.
Explain the role of decomposers in an ecosystem.
Decomposers recycle nutrients, enrich soil, and support plant growth in an ecosystem.
Decomposers are responsible for pollination.
Decomposers primarily consume sunlight.
Decomposers produce energy for animals.
What is the significance of biodiversity in ecosystems?
Biodiversity leads to increased competition among species.
Biodiversity has no impact on ecosystem health.
Biodiversity is only important for aesthetic purposes.
Biodiversity is crucial for ecosystem resilience, stability, and the provision of essential ecological services.
