Food webs, cycling of matter and flow of energy

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

Front

What is the flow of energy in a food web?

Back

Energy flows from producers to consumers and then to decomposers, with each level receiving less energy than the one before it.

Front

What are producers?

Back

Producers are organisms, like plants, that can make their own food through photosynthesis, using sunlight, carbon dioxide, and water.

Front

What are consumers?

Back

Consumers are organisms that cannot produce their own food and must eat other organisms for energy, including herbivores, carnivores, and omnivores.

Front

What are decomposers?

Back

Decomposers are organisms, such as bacteria and fungi, that break down dead organic matter, returning nutrients to the soil.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is a trophic level?

Back

A trophic level is a position in a food chain or food web, representing the flow of energy and nutrients from one level to the next.

Front

What is the role of chloroplasts in plants?

Back

Chloroplasts capture light energy from the sun and convert it into chemical energy through photosynthesis.

Front

What are molecules?

Back

Molecules are substances made up of two or more atoms held together by chemical bonds.
