Energy Flow in Ecosystems Flashcard

Front

What is energy flow in ecosystems?

Back

Energy flow in ecosystems refers to the transfer of energy from one organism to another through food chains and food webs, starting from the sun to producers (plants) and then to consumers (animals).

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (sugar) and oxygen.

Front

Why do animals need to eat plants or other animals?

Back

Animals need to eat plants or other animals to obtain energy that originally came from the sun, as they cannot produce their own food.

Front

What is the primary source of energy for plants?

Back

The primary source of energy for plants is sunlight.

Front

How do plants obtain carbon for growth?

Back

Plants obtain carbon for growth from carbon dioxide in the air.

Front

What role do producers play in an ecosystem?

Back

Producers, like plants, convert sunlight into energy and form the base of the food chain, providing energy for consumers.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that eat other organisms (plants or animals) to obtain energy.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.

Front

What is a food web?

Back

A food web is a complex network of interconnected food chains in an ecosystem, showing how different organisms are related through energy flow.

Front

What is respiration in plants?

Back

Respiration in plants is the process of breaking down glucose to release energy for growth and other functions, using oxygen and producing carbon dioxide.
