Front

What is the primary source of energy for autotrophs?

Back

The sun.

Front

What is a trophic level?

Back

An organism's position in a food chain.

Front

What role do decomposers play in an ecosystem?

Back

They break down dead organisms and waste, returning nutrients to the soil.

Front

How do autotrophs and heterotrophs interact in an ecosystem?

Back

One consumes the other to use energy that originally came from the sun.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food using sunlight or inorganic substances, while heterotrophs consume other organisms for energy.

Front

What is an example of a decomposer?

Back

Earthworm.

Front

What is the significance of energy transfer in a food web?

Back

It illustrates how energy flows from producers to various consumers and decomposers.

Front

What is the role of producers in an ecosystem?

Back

Producers, like plants, convert solar energy into chemical energy through photosynthesis.

Front

What is a food chain?

Back

A linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the difference between a food chain and a food web?

Back

A food chain is a single pathway of energy flow, while a food web consists of multiple interconnected food chains.
