A network of interconnected food chains showing the flow of energy in an ecosystem.

What do arrows in a food web represent?

The direction of energy flow, from the source of food to the consumer.

What is a primary consumer in a food web?

An organism that feeds directly on producers.

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

A food chain is a single path of energy transfer, while a food web shows multiple interconnected chains.

How do decomposers contribute to a food web?

They break down dead organisms and recycle nutrients back into the ecosystem.

Why are predators important in a food web?

They help control the population of other organisms and maintain the balance of the ecosystem.

What happens to energy as it moves through a food web?

Energy is lost as heat at each trophic level, resulting in less energy available at higher levels.

Define a trophic level in a food web.

Each step in a food chain or web where energy is transferred between organisms.

How are food webs affected by changes in the ecosystem?

Changes in one population can affect many other species in the web, leading to a ripple effect.

Which of the following best describes a food web?

A single chain of energy transfer

A single food chain

A network of interconnected food chains

A chain of carnivores

What is the main role of decomposers in a food web?

Predators of the ecosystem

Primary consumers

Recycling nutrients back into the ecosystem

Energy producers

Which organism is typically found at the top of a food web?

Primary consumer

Producer

Apex predator

Decomposer

What do the arrows in a food web indicate?

Direction of energy flow

Predator-prey relationship

Competition among species

Migration patterns

Why are predators important in maintaining a balanced ecosystem?

They produce food for other organisms

They control population sizes

They provide energy for decomposers

They help in pollination

What happens to energy as it is transferred through a food web?

It is produced by decomposers

It is doubled at each trophic level

It is lost as heat

It is stored in predators

Which statement best describes a trophic level in a food web?

A specific habitat

A step in the energy transfer between organisms

A group of producers

A type of decomposer

How are food webs affected by changes in one population?

Many other species are impacted

Only the immediate predators are affected

The producers are unaffected

Decomposers become more active

What sets a food web apart from a food chain?

It has less energy flow

It includes only carnivores

It shows multiple interconnected chains

It consists of only two trophic levels

Why is understanding a food web important for ecosystem management?

It helps in predicting ecosystem responses to changes

It determines the color of producers

It controls the climate of the ecosystem

It provides shelter for consumers
